A rectangular patch antenna is designed as reference. Then shaping is used on the antenna. The radiating edges of the patch antenna are designed as V shape rather than straight line, and the ground plane is shifted up to the same plane of the patch. This mitigates the discontinuity on the surface of the low RCS platform caused by antenna and thus decreases RCS at grazing incidence. The radiation performance does not change too much except some bandwidth reduction. To study the stealth performance of the two antennas at grazing incidence, a platform with relatively low RCS is designed. The reference antenna and the proposed antenna are then mounted on the low RCS platform to study their stealth performance. Results show that the shaping technique is useful for RCS reduction especially for vertical polarization plane wave.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122768340","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}

By etching interdigital slots as capacitive components on the HMSIW surface, a balanced composite right/left-handed (CRLH) structure is realized. This CRLH HMSIW leaky-wave antenna has a continuous beam-steering capability from -20° in the left-handed region to +15° in the right-handed region. With the cutoff frequency of 22.5GHz, the backfire/endfire radiation is obtained when the antenna works below/above its characteristic cutoff frequency and the broadside radiation is achieved at this balancing frequency point. The S-parameters and radiation parameters are presented. Measured results are closely consistent with the simulation. The proposed LW antenna shows some desirable merits, such as the simplicity in design, low-cost fabrication, and beam-steering capability which provides flexibility for the real application.","PeriodicalId":438795,"journal":{"name":"2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127100961","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 LNA is implemented through TSMC 0.18-μm 1P6M CMOS process. Simulation results show that the proposed LNA can get 18.4 dB voltage gain, 4.5 dB NF at 24 GHz with 11.8 mA current consumption.
