摘要:
提出一种小型方向图可重构天线.该天线是由4个缝隙单元组成的平面阵列,单一的缝隙单元能产生定向辐射方向图,且最大辐射方向是接近缝隙的开口端.将4个PIN二极管集成在4个缝隙单元上,通过4个二极管开关的导通与断开组合成不同的模式,使天线在xoy平面上获得8个定向和多个全向的辐射方向图.仿真结果表明:该天线的定向最大增益为2.90 dBi,全向最大增益为1.38 dBi,半功率波束宽度平均值为136°.该天线是半径为31 mm的圆,体积小,制造成本低,且满足无线通信频段2.40~2.50 GHz,适用于无线局域网(WLAN)等无线通信领域,可以降低多径衰落的影响,提高数据的传输速率.
Abstract:
A small pattern reconfigurable antenna is proposed. The antenna is a planar array composed of four slot elements. A single slot element can produce a directional radiation pattern, and the maximum radiation direction is close to the opening end of the slot. Four PIN diodes are integrated into four slot elements, and different modes are formed by the ON-OFF combination of four diode switches. This method is able to generate eight directional and multiple omnidirectional radiation patterns in xoy plane. The simulation results show that the maximum directional gain of the antenna is 2.90 dBi and the maximum omnidirectional gain is 1.38 dBi and that the average value of half power beam width is 136 °. The antenna is a circle with a radius of 31 mm. It is small in size and low in manufacturing cost. It satisfies the wireless communication frequency band 2.40-2.50 GHz. It is suitable for wireless communication fields such as wireless local area network(WLAN). It can reduce the influence of multipath fading and improve data transmission rate.
