Design of Passive Phase Shifter for Beam Steering Applications

Praveen Kumar Kancherla, Habib Ulla Khan

Abstract


The role of phase shifters in the field of beam steerable antennas is vital. The paper presents a navel technique in designing of phase shifters. This technique is facilitating many advantages along with phase shifting, such as reducing mutual coupling between array antenna elements results reduction in overall antenna size and miniaturize the radiating antenna aperture. This structure also shields the components behind the antenna. This method helps in eliminating the use of active elements in architecture and tuning of its reactance with external control circuitry. This proposal is producing an inbuilt tunable capacitive reactance, which helps to steer the beam. For analysis, numerical technique of Finite Element Method is used. The results obtained in HFSS simulation software are presented.
