Abstract—This paper presents a circular ring antenna fed by two perpendicular probes, both of which are placed above the square reflector. The antenna is employed to radiate unidirectional beam for polarization diversity reception. A linear isolator is added to improve the isolation between the two probes. The antenna is proposed for the point-to-point(More)
The objective of this paper is to propose a unidirectional antenna using circular disc monopole excited circular ring above cylindrical reflector to cover the frequency of 3.1-10.6 GHz for ultra-wideband (UWB) applications. The simulated results are presented ultra-wideband performance of this antenna by using Computer Simulation Technology (CSTreg). The(More)
