First, a circularly polarized antenna is designed to obtain a high gain of 9.82 dB at 868 MHz.

The overall dimension of the structure is about (1.73 λ<sub>0</sub> * 1.5 λ<sub>0</sub> * 0.53 λ<sub>0</sub>), where λ<sub>0</sub> is the free-space operating wavelength. The simulation results yield a 13.12 dB realized gain, 1.61 % 3 dB gain bandwidth and an axial ratio less than 3 dB with a ±33° beamwidth at 868 MHz.

The PMC/PEC parallel plates are mainly used to reduce the mutual coupling between two aperture coupled cylindrical DRAs excited in their fundamental modes HEM11δ. The DRAs are separated by 0.5 λ and operated at millimeter-waves. The PMC/PEC plates are composed of a PEC layer and a PMC layer. Using this approach, a minimum mutual coupling reduction of 15.5 dB is achieved at 64 GHz. Furthermore, a superstrate is also used to increase the gain for compensating the path losses and oxygen absorption at 60 GHz. Simulations of S parameters and gain are obtained using HFSS and confirmed the principle of mutual coupling reduction by the proposed PMC/PEC parallel plates. This approach can be used in DRA arrays for millimeter-waves MIMO applications.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126396669","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}

Mixers are one of the fundamental components of many receivers and transmitters, especially in the microwave range. Any mixer-based receiving or transmitting system requires that each mixer has well-known amplitude, group delay and phase responses. A linear phase and constant group delay in particular are essential for low bit error rates (BER) during data transmission in wireless and satellite communications systems and for high target resolution for phased array antenna modules in surveillance systems. Some techniques will be introduced and discussed to address the challenging determination of mixer group delay. In particular, several cases will be included: differential and I&Q mixers, as well as mixers with an embedded LO with no common reference frequency signal accessible. Finally, the procedure to measure the group delay of a satellite in orbit will be presented.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130383287","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}

Higher order broadside modes are studied in this paper. Radiation pattern shaping of these modes has been attempted here to make them useful for various applications. The evolution of designs is inspired by the concept of metascreens. Significant sidelobe reduction is achieved in TM12 and TM13 modes which ultimately lead to novel antenna configurations. The principal idea here is to tailor the current distribution on patch surface via using array subwavelength slots and making it behave as a low impedance surface to get the desired pattern.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117127085","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}

After simplification, the power received by the radar is calculated using the electric field equation.
