Abstract

A wideband and low-profile magneto-electric (ME) dipole antenna loaded with a metasurface is proposed. First, broadband operation is achieved by combining the resonances of the ME dipole and the metasurface. Then, to address the issue of gain degradation at high frequency, I-shaped slots are introduced on the electric dipole to adjust the current distribution for suppressing the undesired common-mode resonance. The antenna is fabricated by two substrates with a low-profile of only 0.063λ_center (λ_center denotes the wavelength at the center frequency). Both simulation and measurement results confirm that the proposed antenna operates over a frequency range of 10.65 GHz to 16.45 GHz, achieving a bandwidth of 42.8% and a peak gain of 8.7 dBi, covering the majority of X/Ku band. These features make the proposed antenna attractive for conformal antenna and array antenna designs in satellite communication system.

一种带开槽电偶极子的宽带低轮廓磁电偶极子天线

提出了一种加载超表面的宽带低轮廓磁电偶极子天线。首先，通过结合ME偶极子和超表面的共振实现宽带操作。然后，为了解决高频增益退化的问题，在电偶极子上引入i形槽来调节电流分布以抑制不希望的共模谐振。该天线由两个低轮廓仅为0.063λ中心（λ中心表示中心频率处的波长）的衬底制成。仿真和测量结果证实，该天线工作在10.65 GHz ~ 16.45 GHz的频率范围内，带宽为42.8%，峰值增益为8.7 dBi，覆盖了大部分X/Ku频段。这些特点使该天线在卫星通信系统的共形天线和阵列天线设计中具有吸引力。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
