摘要

摘要在这项工作中，介质谐振器天线元件以特定的方式形成波纹，从而增加了其半功率波束宽度（HPBW）。对不同波纹深度值的天线的HPBW进行了研究，得出的结论是，可以通过增加波纹深度来增加HPBW。通过在DRA壁中嵌入周期性凹槽，可以调节上壁与侧壁的辐射强度比。通过增大该比率，可以增大天线的HPBW。为了验证光束加宽方法的概念，制作并测量了波纹DRA的原型。测量结果显示阻抗带宽为23%（3.8–4.8 GHz）。4.1时测得的E和H平面HPBWs GHz分别为137°和123°。实测结果与模拟结果吻合较好。

Novel corrugated rectangular dielectric resonator antenna with wide half power beam width

ABSTRACT In this work, a dielectric resonator antenna element is corrugated in a specific way, which led to increase its half power beam width (HPBW). The HPBW of the antenna is investigated for different values of corrugation depth and it has been concluded that HPBW can be increased by increasing this depth. By embedding periodic grooves in the DRA walls, it is possible to adjust the radiation intensity ratio of the upper wall to the side walls. By increasing this ratio, the HPBW of the antenna can be increased. To confirm the concept of beam widening method, a prototype of the corrugated DRA is fabricated and measured. Measured results show an impedance bandwidth of 23% (3.8–4.8 GHz). The measured E- and H-plane HPBWs at 4.1 GHz are 137° and 123°, respectively. Measured and simulated results are in a good agreement.

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.
