Description
本新型是有關於一種天線，特別是指一種可切換強波功能的切換式天線。The present invention relates to an antenna, and more particularly to a switched antenna capable of switching strong waves.
2012年，政府大力推廣無線電視數位化，不僅將無線電視的類比信號關閉，而全面地轉換成數位化信號。民眾只需完成接收天線的安裝，即可透過影音裝置播放15至20台免付收視費的高畫質電視節目。直至今日，目前能收看無線電視數位節目的收視戶，約已超過350萬戶。In 2012, the government vigorously promoted the digitalization of wireless TVs, which not only turned off analog signals of wireless TVs, but also fully converted them into digital signals. The public only needs to complete the installation of the receiving antenna, and can broadcast 15 to 20 high-definition TV programs without paying the viewing fee through the audio-visual device. Up to now, there are more than 3.5 million viewers who can watch digital TV programs.
然而，部分地區因與數位信號發射站相距過遠，或是信號的傳輸路徑受到阻擋，致使接收品質不佳，而造成播放時產生影像破格、停頓、斷訊等問題。此時，使用者常以強波器(Booster)作為信號加強的手段，期能改善收訊品質，但往往改善的效果有限。這是因為強波器必須在信號強度足夠的情況下才能有效地對信號增強，而使電視收訊品質提升。若來源的信號強度不足，或是信雜比(Signal Noise Ratio，SNR)過低。此時，利用強波器進行信號振幅增益，也跟著把雜訊跟干擾的振幅放大，使得 接收到的信號與雜訊同時播放到電視上，收訊品質依然無法獲得改善。另外，在信號強度已經足夠的地區使用強波器也會造成收訊品質的下降，因為透過強波器進行信號振幅增益後，可能會產生信號過載(Overload)，而讓電視顯現出影像失真的問題。However, in some areas, the distance from the digital signal transmitting station is too far, or the transmission path of the signal is blocked, resulting in poor reception quality, which causes problems such as image breakage, pause, and disconnection during playback. At this time, users often use Booster as a means of signal enhancement, which can improve the quality of reception, but often the effect of improvement is limited. This is because the strong wave must be able to effectively enhance the signal when the signal strength is sufficient, and the TV reception quality is improved. If the source signal strength is insufficient, or the Signal Noise Ratio (SNR) is too low. At this time, the signal amplitude gain is performed by the strong wave device, and the amplitude of the noise and the interference is also amplified, so that The received signal and the noise are simultaneously played on the TV, and the quality of the reception still cannot be improved. In addition, the use of a strong wave filter in a region where the signal strength is sufficient will also cause a drop in the quality of the reception. Because the signal amplitude gain is transmitted through the strong wave device, an over-load may occur, and the television may exhibit image distortion. problem.
因此，本新型之目的，即在提供一種能根據接收信號的品質，而自動或手動地開關信號振幅增益功能，以適當地提高收訊品質的切換式天線。Therefore, an object of the present invention is to provide a switched antenna that can automatically or manually switch the signal amplitude gain function according to the quality of the received signal to appropriately improve the reception quality.
於是，本新型切換式天線，包含一天線單元，及一增益切換單元。Thus, the novel switched antenna includes an antenna unit and a gain switching unit.
該天線單元用以接收一無線信號，並輸出一相關於該無線信號的天線信號。The antenna unit is configured to receive a wireless signal and output an antenna signal related to the wireless signal.
該增益切換單元電連接該天線單元，並包括一功率放大模組。該功率放大模組接收該天線信號，並輸出一相關於該天線信號的增益信號。其中，該功率放大模組受一切換信號控制，而在一強波模式與一非強波模式之間切換。在該強波模式下，該功率放大模組使該增益信號振幅的增益為正值；在該非強波模式下，該功率放大模組使該增益信號振幅的增益不為正值。The gain switching unit is electrically connected to the antenna unit and includes a power amplifying module. The power amplification module receives the antenna signal and outputs a gain signal related to the antenna signal. Wherein, the power amplification module is controlled by a switching signal, and switches between a strong wave mode and a non-strong wave mode. In the strong wave mode, the power amplification module makes the gain of the gain signal amplitude a positive value; in the non-strong wave mode, the power amplification module makes the gain of the gain signal amplitude not a positive value.
本新型之功效在於：藉由該天線信號的強弱，而能自動或手動地調整該切換信號，以開關該功率放大模組對該天線信號振幅增益的功能，而適當地提高收訊品質。The function of the present invention is that the switching signal can be automatically or manually adjusted by the strength of the antenna signal to switch the power amplification module to the amplitude gain of the antenna signal, and the receiving quality is appropriately improved.

本新型之其他的特徵及功效，將於參照圖式的實施方式中清楚地呈現，其中：圖1是一信號流程圖，說明本新型切換式天線的一第一實施例；圖2是一信號流程圖，說明本新型切換式天線的一第二實施例；及圖3是一信號流程圖，說明本新型切換式天線的一第三實施例。Other features and effects of the present invention will be apparent from the following description of the drawings.

在本新型被詳細描述之前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.
參閱圖1，本新型切換式天線的一第一實施例，包含一天線單元1、一增益切換單元2，及一傳輸單元3。Referring to FIG. 1, a first embodiment of the switched antenna of the present invention includes an antenna unit 1, a gain switching unit 2, and a transmission unit 3.
該天線單元1用以接收一無線信號，並輸出一相關於該無線信號的天線信號。The antenna unit 1 is configured to receive a wireless signal and output an antenna signal related to the wireless signal.
該增益切換單元2電連接該天線單元1，並包括一功率放大模組21，及一具有一信號偵測模組221的回授切換電路22。該功率放大模組21具有一放大器211、一介於該天線單元1與該放大器211之間的開關212，及一邏輯閘213。該邏輯閘213輸出一相關於一切換信號的邏輯準位，使該開關212依據該邏輯準位，而呈一短路狀態或一斷路狀態。該開關212在該斷路狀態下，能引導該天線信號輸入該放大器211，而讓該放大器211輸出一增益信號。 其中，該增益信號振幅的增益為正值，使得該功率放大模組21呈一強波模式。另外，該開關212在該短路狀態下，使該天線信號不輸入該放大器211，而直接輸出成該增益信號。所以，該增益信號振幅的增益不為正值，讓該功率放大模組21呈一非強波模式。The gain switching unit 2 is electrically connected to the antenna unit 1 and includes a power amplifying module 21 and a feedback switching circuit 22 having a signal detecting module 221. The power amplifying module 21 has an amplifier 211, a switch 212 between the antenna unit 1 and the amplifier 211, and a logic gate 213. The logic gate 213 outputs a logic level associated with a switching signal to cause the switch 212 to assume a short circuit condition or an open circuit state according to the logic level. In the open state, the switch 212 can guide the antenna signal to the amplifier 211, and the amplifier 211 outputs a gain signal. The gain of the gain signal amplitude is a positive value, so that the power amplification module 21 exhibits a strong wave mode. In addition, in the short-circuit state, the switch 212 causes the antenna signal not to be input to the amplifier 211, but directly outputs the gain signal. Therefore, the gain of the gain signal amplitude is not positive, and the power amplifying module 21 is in a non-strong wave mode.
該傳輸單元3包括一電源模組31，及一帶通濾波器(Band Pass Filter，BPF)32。該電源模組31具有一電力源311，及一電源***器(Power Inserter)312。該電力源311的電能經由該電源***器312，而傳輸至該放大器211，並形成一供電迴路。同時，該帶通濾波器32接收該增益信號，並截取一特定頻段的信號，而輸出一相關於該截取結果的濾波信號。最後，該電源***器312接收該濾波信號，並輸出一相關於該濾波信號的終端信號。The transmission unit 3 includes a power module 31 and a Band Pass Filter (BPF) 32. The power module 31 has a power source 311 and a power inserter 312. The power of the power source 311 is transmitted to the amplifier 211 via the power inserter 312 and forms a power supply loop. At the same time, the band pass filter 32 receives the gain signal and intercepts a signal of a specific frequency band, and outputs a filtered signal related to the interception result. Finally, the power inserter 312 receives the filtered signal and outputs a terminal signal associated with the filtered signal.
與此同時，該信號偵測模組221也接收該濾波信號，並與一信號標準值比較，而輸出相關於該比較結果的該切換信號。要說明的是，該第一實施例是透過回授該濾波信號給該信號偵測模組221，以作為判斷該天線信號的品質優劣。若是該信號偵測模組221依據該濾波信號與該信號標準值之間的比較關係，判斷可以使用該放大器211進行信號增強，則輸出能使該開關212呈該斷路狀態的該切換信號給該邏輯閘213，以將該天線信號的振幅進行正值增益。然而，若是該信號偵測模組221判斷該濾波信號已經達到標準強度，或是偵測到雜訊過多，而不適合使用該放大器211進行信號增強，則輸出能使該開關212呈該短 路狀態的該切換信號給該邏輯閘213，而不對該天線信號的振幅進行正值增益。如此，便能適當地提高收訊品質，而不隨意地使用放大器211進行信號振幅增益。值得一提的是，該第一實施例也可回授該增益信號給該信號偵測模組221，以進行該天線信號的品質判斷，但是為了避免造成與收訊頻道無關的頻率影響到該信號偵測模組221的判斷，故以回授該濾波信號為佳。At the same time, the signal detection module 221 also receives the filtered signal and compares it with a signal standard value to output the switching signal related to the comparison result. It should be noted that the first embodiment is to feedback the filtered signal to the signal detecting module 221 to determine the quality of the antenna signal. If the signal detecting module 221 determines that the amplifier 211 can be used for signal enhancement according to the comparison between the filtered signal and the standard value of the signal, the switching signal that enables the switch 212 to be in the open state is output to the signal. Logic gate 213 to positively gain the amplitude of the antenna signal. However, if the signal detection module 221 determines that the filtered signal has reached the standard intensity or detects too much noise and is not suitable for signal enhancement using the amplifier 211, the output enables the switch 212 to be short. The switching signal of the path state is applied to the logic gate 213 without positive gain of the amplitude of the antenna signal. In this way, the reception quality can be appropriately improved without using the amplifier 211 to perform signal amplitude gain arbitrarily. It is to be noted that the first embodiment can also feedback the gain signal to the signal detection module 221 to perform quality judgment of the antenna signal, but to avoid causing the frequency unrelated to the received channel to affect the The signal detection module 221 determines the feedback signal, so it is preferable to feedback the filtered signal.
藉此，該第一實施例利用該信號偵測模組221接收所回授的該濾波信號來判斷該天線信號的品質，而能自動地開關該功率放大模組21對該天線信號振幅增益的功能，以適當地提高收訊品質。Therefore, the first embodiment uses the signal detection module 221 to receive the filtered signal to determine the quality of the antenna signal, and automatically switches the power amplification module 21 to the antenna signal amplitude gain. Features to properly improve the quality of the reception.
此外，該切換信號也可藉由手動來調整。因此，如圖2所示，本新型切換式天線的一第二實施例，包含一天線單元1、一增益切換單元4，及一傳輸單元3。In addition, the switching signal can also be adjusted manually. Therefore, as shown in FIG. 2, a second embodiment of the switched antenna of the present invention includes an antenna unit 1, a gain switching unit 4, and a transmission unit 3.
其中，該天線單元1和該傳輸單元3，與該第一實施例相同。因此，有關該天線單元1與該傳輸單元3的相關結構將不再贅述。The antenna unit 1 and the transmission unit 3 are the same as the first embodiment. Therefore, the related structure of the antenna unit 1 and the transmission unit 3 will not be described again.
該增益切換單元4電連接該天線單元1，並包括一功率放大模組21，及一切換器23。該功率放大模組21具有一放大器211、一介於該天線單元1與該放大器211之間的開關212，及一邏輯閘213。該切換器23可選擇地在一高電位與一低電位之間切換，並輸出一相關於該切換結果的切換信號。該邏輯閘213根據該切換信號，而輸出一邏輯準位，使該開關212依據該邏輯準位，而呈一短路狀 態或一斷路狀態。該開關212在該斷路狀態下，能引導該天線信號輸入該放大器211，而讓該放大器211輸出一增益信號。其中，該增益信號振幅的增益為正值，使得該功率放大模組21呈一強波模式。另外，該開關212在該短路狀態下，使該天線信號不輸入該放大器211，而直接輸出成該增益信號，所以，該增益信號振幅的增益不為正值，讓該功率放大模組21呈一非強波模式。The gain switching unit 4 is electrically connected to the antenna unit 1 and includes a power amplifying module 21 and a switch 23. The power amplifying module 21 has an amplifier 211, a switch 212 between the antenna unit 1 and the amplifier 211, and a logic gate 213. The switch 23 is selectively switchable between a high potential and a low potential and outputs a switching signal associated with the switching result. The logic gate 213 outputs a logic level according to the switching signal, so that the switch 212 is short-circuited according to the logic level. State or a disconnected state. In the open state, the switch 212 can guide the antenna signal to the amplifier 211, and the amplifier 211 outputs a gain signal. The gain of the gain signal amplitude is a positive value, so that the power amplification module 21 exhibits a strong wave mode. In addition, in the short-circuit state, the switch 212 does not input the antenna signal into the amplifier 211, but directly outputs the gain signal. Therefore, the gain of the gain signal amplitude is not positive, and the power amplification module 21 is presented. A non-strong wave mode.
藉此，當一使用者想用該放大器211對該天線信號的振幅進行增益，則使該切換器23輸出呈該高電位的該切換信號給該邏輯閘213。該邏輯閘213用以將該切換信號轉換成能使該開關212呈該斷路狀態的邏輯準位，以將該天線信號的振幅進行正值增益。然而，若是該使用者不想透過該放大器211對該天線信號的振幅進行增益，則使該切換器23輸出呈該低電位的該切換信號給該邏輯閘213。該邏輯閘213用以將該切換信號轉換成能使該開關212呈該短路狀態的邏輯準位，而不對該天線信號的振幅進行正值增益。因此，該第二實施例是由該使用者判斷，並手動地開關該功率放大模組21對該天線信號振幅增益的功能。Thereby, when a user wants to use the amplifier 211 to gain the amplitude of the antenna signal, the switch 23 outputs the switching signal having the high potential to the logic gate 213. The logic gate 213 is configured to convert the switching signal into a logic level that enables the switch 212 to assume the open state to perform a positive gain on the amplitude of the antenna signal. However, if the user does not want to gain the amplitude of the antenna signal through the amplifier 211, the switch 23 outputs the switching signal having the low potential to the logic gate 213. The logic gate 213 is configured to convert the switching signal into a logic level that enables the switch 212 to assume the short-circuit state without performing a positive gain on the amplitude of the antenna signal. Therefore, the second embodiment is a function of the user to manually switch the power amplification module 21 to the antenna signal amplitude gain.
另外，該切換信號也能直接由該天線信號進行調整。因此，如圖3所示，本新型切換式天線的一第三實施例，包含一天線單元1、一增益切換單元5，及一傳輸單元3。In addition, the switching signal can also be directly adjusted by the antenna signal. Therefore, as shown in FIG. 3, a third embodiment of the switched antenna of the present invention includes an antenna unit 1, a gain switching unit 5, and a transmission unit 3.
其中，該天線單元1和該傳輸單元3，與該第一 實施例相同，因此，有關該天線單元1與該傳輸單元3的相關結構將不再贅述。Wherein the antenna unit 1 and the transmission unit 3, and the first The embodiment is the same, and therefore, the related structure of the antenna unit 1 and the transmission unit 3 will not be described again.
該增益切換單元5電連接該天線單元1，並包括一功率放大模組21，及一切換電路24。該功率放大模組21具有一放大器211、一介於該天線單元1與該放大器211之間的開關212，及一邏輯閘213。該切換電路24具有一整波器241，及一信號偵測模組242。該整波器241接收且調整該天線信號，以輸出一相關於該調整結果的檢測信號。該信號偵測模組242接收該檢測信號，並與一信號標準值比較，而輸出一相關於該比較結果的切換信號。該邏輯閘213輸出一相關於該切換信號的邏輯準位，使該開關212依據該邏輯準位，而呈一短路狀態或一斷路狀態。該開關212在該斷路狀態下，能引導該天線信號輸入該放大器211，而讓該放大器211輸出一增益信號。其中，該增益信號振幅的增益為正值，使得該功率放大模組21呈一強波模式。另外，該開關212在該短路狀態下，使該天線信號不輸入該放大器211，而直接輸出成該增益信號。所以，該增益信號振幅的增益不為正值，讓該功率放大模組21呈一非強波模式。The gain switching unit 5 is electrically connected to the antenna unit 1 and includes a power amplifying module 21 and a switching circuit 24. The power amplifying module 21 has an amplifier 211, a switch 212 between the antenna unit 1 and the amplifier 211, and a logic gate 213. The switching circuit 24 has a whole wave 241 and a signal detecting module 242. The wave modulator 241 receives and adjusts the antenna signal to output a detection signal related to the adjustment result. The signal detection module 242 receives the detection signal and compares it with a signal standard value to output a switching signal related to the comparison result. The logic gate 213 outputs a logic level associated with the switching signal, so that the switch 212 assumes a short circuit state or an open state according to the logic level. In the open state, the switch 212 can guide the antenna signal to the amplifier 211, and the amplifier 211 outputs a gain signal. The gain of the gain signal amplitude is a positive value, so that the power amplification module 21 exhibits a strong wave mode. In addition, in the short-circuit state, the switch 212 causes the antenna signal not to be input to the amplifier 211, but directly outputs the gain signal. Therefore, the gain of the gain signal amplitude is not positive, and the power amplifying module 21 is in a non-strong wave mode.
藉此，該天線信號同時輸入該功率放大模組21與該切換電路24，而由該切換電路24的整波器241進行濾波或振幅調整，並輸出該檢測信號，以作為該信號偵測模組242判斷該天線信號是否適合使用該放大器211進行振幅增益的依據。若是該信號偵測模組242判斷該天線信號 可以使用該放大器211進行信號增強，則輸出能使該開關212呈該斷路狀態的該切換信號給該邏輯閘213，以將該天線信號的振幅進行正值增益。然而，若是該信號偵測模組242判斷該天線信號已經達到標準強度，或是偵測到雜訊過多，而不適合使用該放大器211進行信號增強，則輸出能使該開關212呈該短路狀態的該切換信號給該邏輯閘213，而不對該天線信號的振幅進行正值增益。如此，便能自動地提高收訊品質。Thereby, the antenna signal is simultaneously input to the power amplifying module 21 and the switching circuit 24, and the filtering or amplitude adjustment is performed by the whole waver 241 of the switching circuit 24, and the detection signal is output as the signal detecting mode. Group 242 determines if the antenna signal is suitable for use in the amplifier 211 for the basis of amplitude gain. If the signal detection module 242 determines the antenna signal The amplifier 211 can be used for signal enhancement, and the switching signal that enables the switch 212 to assume the open state is output to the logic gate 213 to positively gain the amplitude of the antenna signal. However, if the signal detecting module 242 determines that the antenna signal has reached the standard intensity or detects too much noise and is not suitable for signal enhancement using the amplifier 211, the output enables the switch 212 to be in the short circuit state. The switching signal is applied to the logic gate 213 without a positive gain on the amplitude of the antenna signal. In this way, the quality of the reception can be automatically improved.
值得一提的是，上述該等實施例是利用不同的方式產生該切換信號，以進行信號振幅增益的開關。其中，該等方式可以藉由一多工器(Multiplexer)來進行判斷整合，並依一邏輯運算，而輸出一相關於該運算結果的切換信號，不僅能使該放大器211的使用時機更加準確，並且可因時制宜地選擇自動或手動開關對該天線信號振幅增益的功能。It is worth mentioning that the above embodiments are switches that generate the switching signal in different ways to perform signal amplitude gain. Wherein, the method can be judged and integrated by a multiplexer, and a switching signal related to the operation result is output according to a logic operation, so that the timing of using the amplifier 211 can be more accurate. And the function of automatically or manually switching the amplitude gain of the antenna signal can be selected according to the time.
綜上所述，本新型切換式天線能根據該天線信號的品質優劣，而自動地開關信號振幅增益的功能，以適當地提高收訊品質。另外，也可以由該使用者手動地開關信號振幅增益的功能，使用上兼具彈性，故確實能達成本新型之目的。In summary, the novel switched antenna can automatically switch the function of the signal amplitude gain according to the quality of the antenna signal to appropriately improve the receiving quality. In addition, the user can manually switch the function of the signal amplitude gain, and the use is both elastic, so that the object of the present invention can be achieved.
惟以上所述者，僅為本新型之較佳實施例而已，當不能以此限定本新型實施之範圍，凡是依本新型申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本新型專利涵蓋之範圍內。However, the above is only a preferred embodiment of the present invention, and when it is not possible to limit the scope of the present invention, any simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification are It is still within the scope of this new patent.
