This was achieved by varying the geometry of frequency selective surface so as to make the total surface reactance of cloak equal to that of the reactance produced by the scattering property of the conducting object. The modulated meta-surface structure designed using CST microwave studio suite can cloak the conducting object from two different frequencies of 4 GHz and 5 GHz. The simulated result of the electric field distribution and the lower Radar Cross Section value verifies the cloaking effect at these dual frequencies.","PeriodicalId":259227,"journal":{"name":"2017 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131693382","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 mobile communication systems, such as a LTE system, employs MIMO techniques, carrier aggregation, mutli-band frequencies, etc. The transmitter on a mobile base station transmits broadband, high power, and multi-frequency signals. The receiver on the base station employs high performance frequency selective filters to avoid the interference from the transmitter. This paper investigated the relationship between the LNA performances, linearity and noise figure, and the receiver performances. The investigation also indicated the high linearity LNA enables to decrease the required filter performances on the receiver, resulting in low cost and compact base station.

Direct Conversion Receiver is attractive due to low power, small size and highly monolithic integratable structure, but distortions affect its performance. Second order Intermodulation distortion is the one of the major distortion which is responsible for performance degradation. In this paper, a novel method for Direct Conversion Receiver is suggested, which makes it insensitive to the Second order Intermodulation distortion. Results demonstrate that proposed method is able to remove Second-Order Intermodulation distortion effectively and improve adjacent channel rejection by 10dB. Here the classical homodyne architecture is modified to nullify effect of Second order Intermodulation distortion. The proposed method can be implemented in the Digital Signal Processing (DSP) back-end section also. This feature makes it acceptable in the already designed/functioning classical homodyne architecture based receiver.","PeriodicalId":259227,"journal":{"name":"2017 IEEE MTT-S International Microwave and RF Conference (IMaRC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130448644","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}
