Abstract

Abstract A stacked dielectric magnetoelectric antenna with embedded ceramics (SDMEA-EC) is proposed. The antenna consists of a stacked dielectric resonator antenna with embedded ceramics and a leaf-shaped electric dipole (LSE-Dipole). To improve the performance of the magnetoelectric dipole antenna, a novel verification method is proposed by analyzing equivalent magnetic currents to meet the Huygens element principle. The stacked structure with embedded ceramics is helpful for expanding the impedance bandwidth. The electric dipole not only participates in the radiation but also is a part of the feed network, which simplifies the overall structure. The prototype of the proposed stacked dielectric resonator magnetoelectric antenna achieves an impedance bandwidth of 20.2 % in the high frequency band (5.35 GHz–6.55 GHz) and 13.4 % in the low frequency band (4.54 GHz–5.19 GHz), an over 6.7 dBi gain, and a cross-polarization discrimination (XPD) of greater than 30 dB.

嵌入陶瓷的堆叠介质磁电偶极子天线

摘要提出了一种嵌入陶瓷的堆叠介质磁电天线(SDMEA-EC)。该天线由嵌入陶瓷的堆叠介质谐振器天线和叶状电偶极子(LSE-Dipole)组成。为了提高磁电偶极子天线的性能，提出了一种基于惠更斯元素原理的等效磁流验证方法。嵌入陶瓷的叠层结构有助于扩大阻抗带宽。电偶极子不仅参与辐射，而且作为馈电网络的一部分，简化了馈电网络的整体结构。所提出的叠层介质谐振器磁电天线原型在高频(5.35 GHz - 6.55 GHz)和低频(4.54 GHz - 5.19 GHz)的阻抗带宽分别为20.2 %和13.4 %，增益超过6.7 dBi，交叉极化辨别(XPD)大于30 dB。

期刊介绍： Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
