Abstract |
The evolution of phased-array technology to its present sophisticated form is strongly based on the development of electronically variable phase shifters. In this paper, Six bit digital phase shifter for transmit-receive (TR) module associated with each antenna in a circular array of 576 Yagi-Uda antennas for the Stratospheric Tropospheric (ST) Radar has been designed using Tee networks. It is designed to achieve the beamsteering capability of 360° azimuthal and ±15° elevation. The proposed design had been mathematically modeled, and further verified computationallyin MATLAB. This complete design has been simulated in Advanced Design System (ADS) software using the synthesized lumped component values. The phase shifter has been designed to work at the operating frequency of 212MHz and the results for phase shifts, phase error, insertion loss, return loss for the designed phase shifter has been obtained for all the 64 control signals over a range of frequency. | |||||||||
