摘要

摘要本文提出了一种尺寸紧凑的宽带介质谐振天线。所提出的天线由四种电介质形成。非相邻电介质具有相同的介电常数。50欧姆微带馈线用于通过耦合槽激励天线。通过优化天线的尺寸和结构，阻抗带宽为3.25至4.4 获得GHz。与以前的电介质天线相比，所提出的天线的阻抗带宽是非常宽的带宽。天线增益约为9.6 dB。

A novel wideband dielectric resonator antenna with compact size

ABSTRACT In this paper, a wideband dielectric resonator antenna with compact size is presented. The proposed antenna is formed by four dielectrics. Non-adjacent dielectrics have same permittivity constant. A 50-ohm micro strip feed line is used to exciting the antenna through the coupling slot. By optimizing the dimensions and structure of the antenna, impedance bandwidth of 3.25 to 4.4 GHz is obtained. Impedance bandwidth of the proposed antenna is a very wide bandwidth compared to the previous dielectric antennas. The antenna gain is about 9.6 dB.

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.
