Abstract

This letter introduces a novel dual-band decoupling concept using capacitor-loaded shorting posts as modal tuners to align the resonances of

$\text{TM}_{02}$

and

$\text{TM}_{12}$

with

$\text{TM}_{01}$

and

$\text{TM}_{11}$

, respectively. Leveraging the modal superposition of two pairs of anti-phase current modes, a dual-band, dual-port single-patch antenna is developed, operating in the 3.5 GHz and 5.5 GHz frequency bands. Measurements confirm the design's effectiveness, improving the isolation from 3.5 dBi to over 12 dB, with peak gains of 6.5 dBi and 7.1 dBi in the respective bands.

电容负载短柱（clsp）作为模态调谐器的双带单patch MIMO天线

本文介绍了一种新颖的双频去耦概念，使用负载电容的短柱作为模态调谐器，将$\text{TM}_{02}$和$\text{TM}_{12}$的共振分别与$\text{TM}_{01}$和$\text{TM}_{11}$对齐。利用两对反相电流模式的模态叠加，开发了一种工作在3.5 GHz和5.5 GHz频段的双频双端口单贴片天线。测量结果证实了该设计的有效性，将隔离度从3.5 dBi提高到12 dB以上，在相应频段内的峰值增益为6.5 dBi和7.1 dBi。

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.
