摘　　要：提出了一种应用于无线局域网的小型化定向辐射天线,该天线由辐射单元和反射面组成。辐射单元为共面波导馈电的缝隙天线。反射面为在常规的金属平面上开两同心方环形槽,通过开槽可使得反射面尺寸仅需略大于辐射单元尺寸即可实现天线较好的定向辐射。测试结果表明:天线总电尺寸为0.31λg×0.31λg×0.038λg(其中为频率2.45 GHz时介质基片中的波长),在工作频率内天线的最大增益为5.1 dBi。A compact antenna composed of a radiator and a reflector is presented for wireless local area net applications. The radiator is a slot antenna with coplanar waveguide feed and the reflector is a ring shaped slotted conducting plane. The novelty is the introduction of two ring slots in the reflector and results in small dimension of the reflector and low profile of the proposed antenna. The test results show that the overall size of the proposed antenna is 0.31λg ×0.31λg ×0.038λg(λg is the guide wavelength at the frequency of 2.45 GHz), and the measured peak gain is 5.1 dBi in the operating band.
