Abstract

Double rectangular patch with 4-bridges is investigated for solution of IEEE 802.11b/g (2.4 GHz) and 802.11a (5.5 GHz). Rectangular patch for 5.5 GHz frequency band is printed on the PCB substrate and connected to another rectangular patch for 2.4 GHz frequency band with 4-bridges to obtain dual band operation in an antenna element. 4-bridges can modify the desired frequency band from its original frequency band by changing its width. Gain of 2.4 GHz patch is 5 dBi and 5.5 GHz patch is 3.7 dBi at ${\theta}=0^{\circ}$.

본 논문에서는 WLAN 11 a/b/g 대역(2.4 GHz/5.5 GHz)용 4개의 브릿지(bridge)를 가진 이중 사각 패치(double rectangular patch) 안테나를 소개 하였다. 5.5 GHz 주파수 대역용 평면형 사각 패치는 이중 대역동작을 위해 2.4 GHz에서 동작하는 외부 사각 패치와 4개의 인덕티브 브릿지(inductive bridge)를 통해 연결되어 있다. 제안된 안테나는 4개의 인덕티브 브릿지의 넓이를 가변 하여 사용 주파수 대역을 튜닝 할 수 있으며, 안테나의 최대 이득은 5.5 GHz 주파수 대역에서 3.7 dBi 이고 2.4 GHz 주파수 대역에서는 5 dBi이다.
