技術說明

本發明係有關於一種無線收發器之接收與發射裝置，係針對多輸入多輸出的WLAN 2.45GHz頻帶之高隔離度天線進行開發；該天線採用雙饋入之耦合式單極天線，其具有一介質基板及一多輸入多輸出天線組。該介質基板具有一接地面；接地面上端設有供兩信號源饋入之信號端，而兩信號端之間由接地面延伸出一T字型金屬片，且此金屬片上設有一倒C字型寄生元件，以產生兩者之間距並可以調整隔離度。本發明之天線為對稱模式，可提高隔離度，且適用於適配器(USB Dongle)或小型化之無線行動裝置上。 The present invention relates to a receiving and transmitting device for a wireless transceiver, particularly developed in light of a multi-output multi-input (MIMO) antenna with a high isolation at a WLAN 2.45GHz band. The antenna is a dual port-fed coupling monopole antenna, and provided with a dielectric substrate and a MIMO antenna set. The dielectric substrate has a grounding surface, on the upper end of which two signal ends are provided for feeding of two signal sources. A T-shaped metal sheet extending from the grounding surface between the two signal ends is provided with a parasitic component in an inverted C configuration for generation of a distance therebetween and adjustment of isolation thereof. As a result, this invention is made in a symmetric pattern to increase the isolation and adapted for an USB dongle or a compact wireless mobile device.
