Dual frequency microstrip phased array with hybrid phase shifter

A phased array antenna is mainly designed with numbers of radiating elements each with a phase shifter. Radiation Beams are formed by shifting the phase of the signals emitted from all radiating elements to provide constructive or destructive interference so as to steer the beams in the desired direction. The antenna is the basic element in the field of wireless communication and finds its uses in various applications. For the satellite communications, at the microwave frequencies of the C band perform better under adverse weather conditions in comparison with Ku band (11.2 GHz to 14.5 GHz) microwave frequencies. The adverse weather conditions, can be referred to as rain fade, all have to do with moisture in the air, including rain and snow. This dual frequency Microsrip antenna array is designed on IE3D and Phase shifter is designed with HFSS software's. The phase shifter designed using UWB power divider with branch line coupler. This research provides a detailed insight of design and fabrication process of a phased array antenna with hybrid phase shifter using HFSS software and study the effect of phase shifter and antenna dimensions on the Radiation parameters of Bandwidth and return loss which are very effective parameters for design of antennas.
