In this paper the design of a multimode corrugated feed at centre frequency of 7.25 GHz is presented, which reduces very high level of cross polarization in an offset parabolic reflector antenna system. The higher order modes TE21 and TM11 are generated in proper phase and magnitude in addition to the dominant, TE11 mode, which are passed through the corrugated structure to generate HE11 and HE21...
The author has simulated micro strip patch antenna with prime focus of increasing bandwidth using various techniques of probe feed, parasitic patch around the main patch and two layer of substrate. The simulation process has been done using HFSS (High Frequency Structural Simulator). In this paper, authors cover five aspects of micro strip antenna designs. The first is the analysis of single element...
