The frequency agility is obtained by the integration of a crystal liquid material between the upper face and the substrate of the proposed SIW antenna, this material maintains the proprieties of changing the permittivity and the permeability by applying a DC voltage. This is leads to the variation of the resonance frequency. Simulated results obtained by CST simulator show that the first band is tuned from 27 GHz to 28 GHz, the second one is varied from 27.85 to 29 GHz. and the frequency in the third band is changing from 29.45 GHz to 30.89 GHz. Those results are obtained when the permittivity of the CL is varying from 2.7 to 3.4. The maximum gain is around 7.92 dB and a high radiation efficiency is obtained. The proposed antenna is required for wireless applications.","PeriodicalId":373813,"journal":{"name":"2019 IEEE 19th Mediterranean Microwave Symposium (MMS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133457283","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}

Such approach allows a more efficient resolution of boundary conditions.

Due to the loaded varactors, the operating frequency of the antenna can be tuned in a wide frequency range by changing electric bias. Two samples of frequency reconfigurable SIW cavity backed antennas are presented. They are designed, fabricated and measured. The antenna radiating from a circular slot is designed for low frequency band (2.28 GHz). The antenna radiating from a rectangular slot is designed to radiate at higher frequencies (11 GHz). The experimental results demonstrate the frequency tunability of the antennas.
