摘要

本文介绍了一种采用共面波导馈电技术的多根平面圆极化槽天线。在接平面上引入矩形槽，在矩形槽中插入进料短根，当主短根修改为作为正交进给的结构时，短根结束于正交进给励磁。在该结构中还包括两个矩形接地环以及嵌入在地面中的矩形导电短根，两者均放置在主短根的两侧。在3ghz ~ 4.25 GHz的频率范围内，产生了S11< - 10db，轴比< 3dB的圆极化辐射，激发的谐振带位于ISM波段。

Circular Polarized Coplanar Waveguide Fed Slot Antenna For ISM Band Application

A planar circular polarized slot antenna with multiple stubs using coplanar waveguide feed (CPW) technique is introduced in this letter. A rectangular slot is introduced in the ground plane and a feeding stub is inserted in the rectangular slot with stub ending into a quadrature feed excitation as the primary stub modifies into a configuration which works as quadrature feed. Two rectangular grounded rings are also incorporated in the structure along with a rectangular conducting stub embedded in the ground with both placed on either side of primary stub. This results in generation of circular polarized radiations for a frequency range of 3 GHz to 4.25 GHz for which S11< ‒ 10 dB and Axial ratio < 3dB and the excited resonating band lies in the ISM band.
