Dual-Band Single-Patch MIMO Antenna With Capacitor-Loaded Shorting Posts (CLSPs) as Modal Tuners
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.
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.
