The antenna has a compact size of 0.5λ0 × 0.5λ0 at 30 GHz. It consists of a circular shaped radiating patch fed by a 50-Ω microstrip line via proximity-feed technique. An elliptically shaped slot is etched in the ground plane to enhance the antenna bandwidth. A stub has been added to the microstrip line feed to achieve better impedance matching bandwidth of the antenna. Simulated results indicate that the proposed 5G antenna yields a broadband impedance bandwidth larger than 67% (from 20 GHz to beyond 40 GHz) for S11 less than -10 dB. The achieved bandwidth covers both future 5G bands (28/38 GHz). The proposed antenna provides almost omni-directional patterns, relatively flat gain, and high radiation efficiency through the frequency band excluding the rejected band.","PeriodicalId":447985,"journal":{"name":"2016 17th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128780134","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}

Recent technologies enable electronic and RF circuits in radar and communication devices to be miniaturized and become physically smaller in size. Antenna design has been one of the key limiting constraints to the development of small communication terminals, next generation wireless communication and radar requirements of multi-band and multi-function operation. In this paper, design of miniaturized multifunction two elements microstrip array with single-pole double-throw (SPDT) transmitter/receiver (T/R) switch has been introduced and investigated. The entire proposed array antenna has been evaluated using a commercial software. The final proposed design has been fabricated and the radiation characteristics have been illustrated using network analyzer to meet the requirements for multifunction applications.","PeriodicalId":447985,"journal":{"name":"2016 17th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127640448","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}

However, they are unable to be used at frequencies beyond 500 MHz due to their high loss. The main idea of this paper is to reproduce the magnetic behavior using metallic inclusions for low-loss microwave applications. In this paper, an artificial magneto-dielectric resonator antenna (AMDRA), operating at 3.857 GHz, based on split ring resonator (SRR) is presented. The simulation results are compared to those of the conventional dielectric resonator antenna (DRA) with high permittivity. It is shown that the size of the proposed antenna is 1.8 times smaller than that of the conventional DRA, with an efficiency of 88% and a gain of 5.8 dBi. This demonstrates that the artificially induced permeability can be effectively used in dielectric antenna miniaturization.","PeriodicalId":447985,"journal":{"name":"2016 17th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133800199","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}

It is found that the DDM of sea ice differs from the one of seawater in the aspect of delay and Doppler spreading. This enables to distinguish sea ice from seawater through studying the number of high-value (greater than 50% of the peak power) DDM pixels. The area associated with a DDM with a number of high-value pixels less and greater than an empirical threshold (12) will be classified as covered by sea ice and seawater, respectively. The proposed method is validated by comparing the DDM-based detection results with ground-truth sea ice data and a detection accuracy of 100% is achieved.","PeriodicalId":447985,"journal":{"name":"2016 17th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121928402","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}
