Description
本發明係有關於一種無線收發器之接收與發射的多頻段天線，尤其是指一種具有小尺寸、結構簡單、容易製作，而適用於USB dongle或其他小型無線通訊行動裝置上之多頻段天線。 The present invention relates to a multi-band antenna for receiving and transmitting a wireless transceiver, and more particularly to a multi-band antenna that is small in size, simple in structure, and easy to manufacture, and is suitable for use on a USB dongle or other small wireless communication mobile device.
隨著行動通訊裝置的盛行，通訊時賴以接收、發射訊號的天線設計即格外受到重視，其中單極天線的應用十分普遍，一般單極天線為達良好的輻射效能，必須在無線通訊產品的基板上保留天線淨空區；且近年來不論是筆記型電腦或手機等無線通訊產品外觀的趨勢是輕巧、小型化、高效率，然而淨空區愈大表示佔用空間愈大，在輕巧、小型化的前提下，淨空區勢必必須縮小，甚至無法保有淨空區，有業者為改善此一狀況下於是增加天線的高度，來確保天線的特性，但此將增加天線的體積，因此，如何讓天線的體積變得更 小，而且不會失去效能，並能涵蓋多頻段的天線，將是值得研究的課題。 With the prevalence of mobile communication devices, the antenna design that relies on receiving and transmitting signals is particularly valued. The application of monopole antennas is very common. Generally, monopole antennas have good radiation performance and must be used in wireless communication products. The antenna clearance area is reserved on the substrate; and in recent years, the trend of the appearance of wireless communication products such as notebook computers or mobile phones is light, compact, and high-efficiency. However, the larger the clearance area, the larger the occupied space, and the lighter and smaller. Under the premise, the clearance area must be reduced, and even the clearance area cannot be preserved. In order to improve the height of the antenna, the operator can ensure the antenna characteristics, but this will increase the size of the antenna. Therefore, how to make the size of the antenna Become more Small, and will not lose performance, and can cover multi-band antennas, it will be a topic worth studying.
現今多頻段單極天線，通常在設計之時係以增加多彎折或浮接金屬架構的方式，來增加天線上的電流路徑，並滿足多頻段的需求。 Today's multi-band monopole antennas are often designed to increase the current path on the antenna and increase the multi-band requirements by adding multiple bends or floating metal structures.
請參看我國證書號第M358419號之改善HAC特性之多頻段單極天線新型專利案。該案即係透過增加多彎折的方式增加天線上的電流路徑，以滿足多頻段的需求；即該多頻段單極天線是在第一金屬輻射體之饋入端與第二金屬輻射體之連接端之間連接一曲折繞線部，使該曲折繞線部位在該第一及第二金屬輻射體之同側，且激勵出低頻段。 Please refer to China's certificate number No. M358419 for a new multi-band monopole antenna patent for improving HAC characteristics. In this case, the current path on the antenna is increased by increasing the number of bends to meet the requirements of the multi-band; that is, the multi-band monopole antenna is at the feed end of the first metal radiator and the second metal radiator A zigzag winding portion is connected between the connecting ends, so that the meandering winding portion is on the same side of the first and second metal radiators, and the low frequency band is excited.
然而，天線使用多彎折的技術雖然可以增加電流路徑，亦可達到小型化的設計，但對天線的增益與輻射場型會造成很大的影響，即天線的輻射場型、增益會因天線彎折數增加而變差，其中在輻射場型的部分，將無法產生出較佳的全向性輻射場型，而在增益的部分，則會使增益下降。 However, the technique of using multiple bends in the antenna can increase the current path and achieve a miniaturized design, but it has a great influence on the gain and radiation pattern of the antenna, that is, the radiation field type and gain of the antenna are caused by the antenna. The number of bends increases and becomes worse, in which part of the radiation pattern will not produce a better omnidirectional radiation pattern, while in the gain portion, the gain will decrease.
本發明之主要目的，係因隨著科技時代的進步，無線通訊也發展的迅速，天線尺寸要求越來越小，整體架構也越來越簡單；而現有技術多為了使天線整體尺寸變小，使得天線的輻射場型、增益因此而變差，多無法將天線有效且簡單的設計在天線架構上，故 本發明提出一種架構簡單，並有良好的增益、輻射場型，同時符合時代進步多頻的需求的無線收發器之接收與發射的多頻段天線。該天線係為一小型化並符合WLAN2.45GHz、5.2GHz、5.8GHz多頻帶以及涵蓋於WiMAX(3.4GHz~3.5GHz)之天線，且具有小尺寸、結構簡單、容易製作之特色，故非常適用於USB dongle或其他小型無線通訊行動裝置上。 The main purpose of the present invention is that with the advancement of the technological era, wireless communication has also developed rapidly, the antenna size requirements have become smaller and smaller, and the overall architecture has become more and more simple; and the prior art mostly aims to make the overall size of the antenna smaller. Therefore, the radiation field type and gain of the antenna are deteriorated, and the antenna cannot be effectively and simply designed on the antenna structure. The present invention proposes a multi-band antenna that is simple in architecture, has good gain, radiation field type, and meets the needs of the advanced multi-frequency of the era of receiving and transmitting wireless transceivers. The antenna is a miniaturized and compliant WLAN 2.45 GHz, 5.2 GHz, 5.8 GHz multi-band and WiMAX (3.4 GHz to 3.5 GHz) antenna, and has a small size, simple structure, and easy to manufacture. On a USB dongle or other small wireless mobile device.
