In this paper, an active metamaterial antenna with tunable zero-order resonance(ZOR) is proposed with utilizing Mushroom structure to realize the narrow band. Particularly, varactor diodes are utilized in each unit cell, thus, by supplying different voltages, the capacitance of varactor diodes is changed, resulting in tunable ZORs.

In this study, the magnetostatic spin-wave modes excited as a result of the coupling between the 2D microwave resonator and the YIG sphere have been investigated computationally. The simulations have been performed using commercial finite element method software (CST Studio Suite). The 2D microwave resonator is realized on the ground plane of the broadband microstrip structure by using a low-loss printed circuit board. The calculations reveal the Q factor to be about 300 by optimizing the resonance frequency to 7 GHz. The most interesting result of simulations is the observation that the magneto-static spin-wave modes of the YIG sphere may be excited depending on the geometry of the hybrid structure. A strong interaction between the YIG and the microwave resonator observed in the dispersion curves of these modes reveals the realization of the strong coupling regime, which is a prerequisite of their use in quantum hybrid devices.","PeriodicalId":422383,"journal":{"name":"2022 Photonics & Electromagnetics Research Symposium (PIERS)","volume":"59 Pt A 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114114032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed antenna has a structure based on a microstrip line loaded with X-shaped slots. To generate circularly polarized waves, the feeding position of the microstrip line is shifted from the center of the X-slot to the edge. Then the straight feed line can form the phase difference between two arms of the X-slot without a meandering line, increasing the radiation efficiency. When the phase difference is 90degrees, the two arms radiate orthogonal field within required phases, thus synthesizing circular polarization. The arms of the X-slot have no spatial phase difference which makes the radiating element have a wide CP bandwidth. The simulated results show that the proposed antenna realizes available impedance bandwidth of 45.01% (2.72GHz–4.30GHz) and CP bandwidth of 13.01% (3GHz–3.42GHz). The radiation efficiency of the leaky-wave antenna is from 82.1% to 95.4% and the gain is from 2.48dBi to 3.6dBi with bi-directional radiation in the operating bandwidth. The overall size of the proposed antenna is $0. 356 lambda_{0}, times 0. 356 lambda_{0}$, where $lambda _{0}$ is the free-space wavelength at the center frequency of the operating bandwidth. According to the phase transmission characteristic, it is convenient to extend a backward to forward scanning array with the proposed antenna. With the wide bandwidth and high scanning rate, the array has the potential to realize large-angle frequency scanning with circular polarization. The proposed leaky-wave antenna could be a good choice for radar applications and microwave imaging.","PeriodicalId":422383,"journal":{"name":"2022 Photonics & Electromagnetics Research Symposium (PIERS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128200585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
