Abstract

ABSTRACT The paper addresses the design of microstrip fed slot antenna with bandwidth enhancement and minimization of cross-polarization in planar printed configuration. The reference radiating slot antenna resonates at 2.86 GHz having 5.95% – 10 dB bandwidth. Next, the reference slot antenna is loaded with two rectangular loops and four rectangular loops resulting 13.22% and 33.03% −10 dB bandwidth respectively but with poor cross-polarization. To overcome the problem of poor cross-polarization, we have introduced the split ring in one of our antenna design and metallic rings on the bottom of the substrate in another antenna design. These two designs introduce the oppositely directed phi-component of electric field along the radiating slot which cancels out phi-component of electric field, the root cause of increased cross-polarization.

平面印刷结构下宽带缝隙天线的交叉极化抑制

本文讨论了平面印刷结构中具有带宽增强和交叉极化最小化的微带馈电缝隙天线的设计。参考辐射缝隙天线谐振频率为2.86 GHz，带宽为5.95%–10 dB。接下来，参考缝隙天线加载有两个矩形环路和四个矩形环路，分别得到13.22%和33.03%-10dB带宽，但交叉极化较差。为了克服交叉极化差的问题，我们在一个天线设计中引入了开口环，在另一个天线的设计中在基底底部引入了金属环。这两种设计沿辐射槽引入了方向相反的电场phi分量，抵消了电场的phi分量——交叉极化增加的根本原因。

期刊介绍： Publishing eight times per year, Electromagnetics offers refereed papers that span the entire broad field of electromagnetics and serves as an exceptional reference source of permanent archival value. Included in this wide ranging scope of materials are developments in electromagnetic theory, high frequency techniques, antennas and randomes, arrays, numerical techniques, scattering and diffraction, materials, and printed circuits. The journal also serves as a forum for deliberations on innovations in the field. Additionally, special issues give more in-depth coverage to topics of immediate importance. All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. Submissions can be made via email or postal mail.
