Crossing of λ/4 long micro strip line between both slots at an angle is generating the nature of circular polarization near the 9.5GHz frequency range. Axial Ratio bandwidth (AR ≤ 3 dB) of 9% (825MHz) and impedance bandwidth (S11 ≤ -10 dB) of 37% (3.5GHz) has been shown by the antenna which can be considered large axial ratio bandwidth for single and simple feed CDRA.

The antenna is miniaturized from its natural operating frequency of 3.2 GHz (0.08A0) to 1.85 GHz (0.03A0) which is more than 60% of size reduction. The high selectivity nature of the miniaturized antenna is utilized in receiving front-end design to achieve out-of-band attenuation more than 20 dB which is highly desirable. Moreover, the low noise amplifier (LNA) is designed for noise matching considering the antenna impedance characteristics which ensures optimum noise performance of the overall system. The in-band noise figure and small signal transducer gain of the system is less than 2 dB and more than 10 dB, respectively. The output power and third- order output intercept point (OIP3) of the receiving front-end are found to be more than 20 dBm and 30 dBm, respectively. Such compact radio frequency (RF) front-end with multiple functions like antenna miniaturization, filtering and noise matching is highly appreciated.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122075694","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 effect of both conductor loss and dielectric loss is studied by computing the gain of the antenna at different frequencies.

It is observed that both dielectric loss and conductor loss are inversely proportional to substrate thickness. The analysis shows that dielectric loss is independent of antenna geometry.","PeriodicalId":396210,"journal":{"name":"2017 IEEE International Conference on Antenna Innovations & Modern Technologies for Ground, Aircraft and Satellite Applications (iAIM)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117267363","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}
