Description

天線選擇裝置Antenna selection device

本發明是有關於一種通信裝置，且特別是有關於一種天線選擇裝置。The present invention relates to a communication device, and more particularly, to an antenna selection device.

隨著通信技術的快速發展，人們能透過相關的消費性電子商品或3C產品進行溝通，從而縮短彼此之間的距離。With the rapid development of communication technology, people can communicate through related consumer electronic goods or 3C products, thereby shortening the distance between them.

對於一般的消費者而言，多半希望能夠享受到更為快速的通信體驗。為因應此需求，廠商們須做好提升通信裝置信號品質的準備，例如，通信裝置的接收信號強度指示（Received Signal Strength Indication，RSSI）、傳輸速率，信號品質相關指標參數要好。For the average consumer, most hope to enjoy a faster communication experience. To meet this demand, manufacturers must be prepared to improve the signal quality of communication devices. For example, the Received Signal Strength Indication (RSSI), transmission rate, and signal quality-related index parameters of the communication device should be better.

然而，在現有的通信裝置中，雖可能設置有數組天線，但由於通信裝置自身在選擇天線時未能考慮信號品質，因此可能無法讓通信裝置在良好信號品質的情況下運作。舉例而言，對於具有Wifi通信功能的筆記型電腦而言，其可能設置有分別對應於Wifi 2.4GHz及5GHz等頻段的兩組天線，而此筆記型電腦將因應於所連接的Wifi存取點（access point，AP）所要求使用的頻段而直接在未考慮信號品質的情況下採用上述兩組天線的其中之一，進而導致不佳的收訊效果。However, in the existing communication device, although an array of antennas may be provided, since the communication device itself does not consider the signal quality when selecting the antenna, the communication device may not be able to operate with good signal quality. For example, for a notebook computer with Wifi communication function, it may be provided with two sets of antennas corresponding to Wifi 2.4GHz and 5GHz frequency bands respectively, and the notebook computer will respond to the connected Wifi access point. One of the above-mentioned two sets of antennas is directly used without considering the signal quality according to the frequency band required by the access point (AP), resulting in a poor reception effect.

由上可知，若能設計一種提高通信裝置信號品質的機制，應能讓通信裝置在進行傳輸時得到較佳的傳輸效能。It can be seen from the above that if a mechanism for improving the signal quality of the communication device can be designed, the communication device should be able to obtain better transmission performance during transmission.

有鑑於此，本發明提供一種天線選擇裝置，其可用於解決上述技術問題。In view of this, the present invention provides an antenna selection device, which can be used to solve the above technical problems.

為便於說明，以下略以「第一天線選擇操作」代稱天線選擇裝置100依序將來自各第一天線單元A11~A1N的天線信號S11~S1N個別轉傳至通信模組199的操作，但本發明可不限於此。For the convenience of description, the operation of the antenna selection device 100 to sequentially transfer the antenna signals S11 to S1N from the first antenna units A11 to A1N to the communication module 199 is abbreviated as “the first antenna selection operation” below. But the present invention may not be limited to this.

在一實施例中，天線選擇裝置100可週期性地在不同的時間週期中執行上述第一天線選擇操作，以協助通信模組199在各時間週期中選擇所需的第一天線單元。In one embodiment, the antenna selection apparatus 100 may periodically perform the above-mentioned first antenna selection operation in different time periods, so as to assist the communication module 199 to select the required first antenna unit in each time period.

在第一實施例中，微控制單元102可在一第一時間週期（其長度例如是1800秒）中控制第一切換單元103a依序切換導通第一天線單元A11~A1N，以將來自各第一天線單元A11~A1N的第一天線信號S11~S1N轉傳至通信模組199。相應地，通信模組199可測量各第一天線單元A11~A1N的第一天線信號S11~S1N的信號品質（例如RSSI），並據以從第一天線單元A11~A1N中選擇欲在第一時間週期中使用的第一特定天線單元，其中所述第一特定天線單元在第一天線單元中A11~A1N可具有最佳信號品質。In the first embodiment, the micro-control unit 102 can control the first switching unit 103a to switch on the first antenna units A11-A1N sequentially in a first time period (the length of which is, for example, 1800 seconds), so that the The first antenna signals S11 ˜ S1N of the first antenna units A11 ˜ A1N are forwarded to the communication module 199 . Correspondingly, the communication module 199 can measure the signal quality (eg, RSSI) of the first antenna signals S11 ˜ S1N of the first antenna units A11 ˜ A1N, and select the desired antenna from the first antenna units A11 ˜ A1N accordingly.

舉例而言，假設通信模組199在依序接收第一天線信號S11~S1N之後測得第一天線信號S11具有最高的RSSI，則通信模組199可相應地將第一天線單元A11視為上述第一特定天線單元。之後，微控制單元102可控制第一切換單元103a切換導通第一天線單元A11，以在第一時間週期中轉傳來自第一天線單元A11的第一特定天線信號至通信模組199，以讓通信模組199使用第一天線單元A11進行第一時間週期內的傳輸。For example, if the communication module 199 measures that the first antenna signal S11 has the highest RSSI after receiving the first antenna signals S11 to S1N in sequence, the communication module 199 can correspondingly assign the first antenna unit A11 Considered the above-mentioned first specific antenna element. After that, the micro-control unit 102 can control the first switching unit 103a to switch on the first antenna unit A11, so as to transmit the first specific antenna signal from the first antenna unit A11 to the communication module 199 in the first time period, So that the communication module 199 uses the first antenna unit A11 to perform transmission within the first time period.

舉另一例而言，假設通信模組199在依序接收第一天線信號S11~S1N之後測得第一天線信號S1N具有最高的RSSI，則通信模組199可相應地將第一天線單元A1N視為上述第一特定天線單元。之後，微控制單元102可控制第一切換單元103a切換導通第一天線單元A1N，以在第一時間週期中轉傳來自第一天線單元A1N的第一特定天線信號至通信模組199，以讓通信模組199使用第一天線單元A1N進行第一時間週期內的傳輸。For another example, if the communication module 199 measures that the first antenna signal S1N has the highest RSSI after receiving the first antenna signals S11 to S1N in sequence, the communication module 199 can correspondingly connect the first antenna signal S1N to the first antenna signal S1N. The element A1N is regarded as the above-mentioned first specific antenna element. After that, the micro-control unit 102 can control the first switching unit 103a to switch on the first antenna unit A1N, so as to transmit the first specific antenna signal from the first antenna unit A1N to the communication module 199 in the first time period, So that the communication module 199 uses the first antenna unit A1N to perform transmission within the first time period.

由上可知，本發明的天線選擇裝置100可讓通信模組199得以在第一時間週期內以較佳的RSSI進行傳輸，從而提升通信模組199於第一時間週期內的傳輸表現。As can be seen from the above, the antenna selection device 100 of the present invention enables the communication module 199 to transmit with a better RSSI in the first time period, thereby improving the transmission performance of the communication module 199 in the first time period.

此外，在第一時間週期後的其他時間週期中，天線選擇裝置100皆可執行上述第一天線選擇操作，以協助通信模組199於各個時間週期中選擇具較佳信號品質的第一特定天線單元進行傳輸，但可不限於此。In addition, in other time periods after the first time period, the antenna selection device 100 can perform the above-mentioned first antenna selection operation to assist the communication module 199 to select the first specific antenna with better signal quality in each time period The antenna unit transmits, but may not be limited thereto.

此外，在第二實施例中，在通信模組199決定欲在第一時間週期中使用的第一特定天線單元之後，通信模組199可持續監控第一特定天線信號的信號品質。在第一時間週期中，若通信模組199判定第一特定天線信號的信號品質的變化幅度超過一閾值，則天線選擇裝置100可於第一時間週期中再次執行上述第一天線選擇操作，以協助通信模組199重新決定欲使用的第一特定天線單元。Furthermore, in the second embodiment, after the communication module 199 determines the first specific antenna unit to be used in the first time period, the communication module 199 may continuously monitor the signal quality of the first specific antenna signal. In the first time period, if the communication module 199 determines that the variation range of the signal quality of the first specific antenna signal exceeds a threshold, the antenna selection apparatus 100 may perform the above-mentioned first antenna selection operation again in the first time period, In order to assist the communication module 199 to re-determine the first specific antenna unit to be used.

舉例而言，假設通信模組199在天線選擇裝置100執行上述第一天線選擇操作之後決定以第一天線單元A11作為欲在第一時間週期中使用的第一特定天線單元，則微控制單元102可相應地轉傳來自第一天線單元A11的第一特定天線信號（例如第一天線信號S11）至通信模組199。之後，在第一時間週期的剩餘時間區間中，通信模組199可持續監控第一天線信號S11的信號品質。For example, if the communication module 199 decides to use the first antenna unit A11 as the first specific antenna unit to be used in the first time period after the antenna selection device 100 performs the above-mentioned first antenna selection operation, the micro-control The unit 102 can correspondingly transmit the first specific antenna signal (eg, the first antenna signal S11 ) from the first antenna unit A11 to the communication module 199 . After that, in the remaining time interval of the first time period, the communication module 199 can continuously monitor the signal quality of the first antenna signal S11.

在此情況下，若第一天線信號S11的信號品質的變化幅度超過一閾值（例如30%），則天線選擇單元100可再次執行上述第一天線選擇操作。In this case, if the variation range of the signal quality of the first antenna signal S11 exceeds a threshold (eg, 30%), the antenna selection unit 100 may perform the above-mentioned first antenna selection operation again.

具體而言，微控制單元102可相應地控制第一切換單元103a依序切換導通第一天線單元A11~A1N，以將來自各第一天線單元A11~A1N的第一天線信號S11~S1N轉傳至通信模組199。之後，通信模組199可再次測量各第一天線單元A11~A1N的第一天線信號S11~S1N的信號品質，並據以再次從第一天線單元A11~A1N中選擇欲使用的另一特定天線單元，其中所述另一特定天線單元在第一天線單元A11~A1N中具有最佳信號品質。相應地，微控制單元102可控制第一切換單元103a切換導通所述另一特定天線單元，以轉傳來自所述另一特定天線單元的另一特定天線信號至通信模組199。Specifically, the micro-control unit 102 can correspondingly control the first switching unit 103a to switch on the first antenna units A11 - A1N in sequence, so as to convert the first antenna signals S11 - A1N from the first antenna units A11 - A1N. The S1N is forwarded to the communication module 199 . After that, the communication module 199 can measure the signal quality of the first antenna signals S11 ˜ S1N of the first antenna units A11 ˜ A1N again, and select another one to be used from the first antenna units A11 ˜ A1N accordingly.

Correspondingly, the micro-control unit 102 can control the first switching unit 103 a to switch on the other specific antenna unit to transmit another specific antenna signal from the other specific antenna unit to the communication module 199 .

舉例而言，假設通信模組199經再次測量各第一天線信號S11~S1N之後判定第一天線信號S1N具有最高的RSSI，則通通模組199可據以另選擇第一天線單元A1N作為欲在第一時間週期的剩餘時間區間內使用的另一特定天線單元。相應地，微控制單元102可控制第一切換單元103a切換導通第一天線單元A1N，以轉傳來自第一天線單元A1N的第一天線信號S1N至通信模組199。For example, if the communication module 199 determines that the first antenna signal S1N has the highest RSSI after measuring the first antenna signals S11 to S1N again, the communication module 199 can select the first antenna unit A1N accordingly.

此外，在第三實施例中，在通信模組199決定欲在第一時間週期中使用的第一特定天線單元之後，天線選擇裝置100可在第一時間週期中的一特定時間點（例如第一時間週期的50%）再次執行上述第一天線選擇操作，以協助通信模組199重新決定欲使用的第一特定天線單元。In addition, in the third embodiment, after the communication module 199 determines the first specific antenna unit to be used in the first time period, the antenna selection device 100 may select a specific time point in the first time period (for example, the first specific antenna unit 50% of a time period) to perform the above-mentioned first antenna selection operation again to assist the communication module 199 to re-determine the first specific antenna unit to be used.

舉例而言，假設天線選擇裝置100已於第一時間週期的一起始時間點執行第一次第一天線選擇操作以協助通信模組199選擇第一天線單元A11作為上述第一特定天線單元。在此情況下，天線選擇裝置100還可在第一時間週期中的特定時間點執行第二次第一天線選擇操作。For example, it is assumed that the antenna selection apparatus 100 has performed the first antenna selection operation for the first time at a starting time point of the first time period to assist the communication module 199 to select the first antenna unit A11 as the above-mentioned first specific antenna unit . In this case, the antenna selection apparatus 100 may also perform the second first antenna selection operation at a specific time point in the first time period.
