Abstract

This paper proposes the design of 4-element microstrip phased array antenna integrated with reflection
type phase shifter loaded with the varactor diode. Steering of the main lobe is done by changing the bias voltage which
leads to progressive phase-shift of phase shifter. The structure of phase shifter is based on 900
branch line coupler
loaded with the varactor diodes used to provide the phase shifting. Feeding the quadrature hybrid reflection type
phase shifter a wilkinson power divider is used. This approach of fabrication of various component can be used for
large phased array for use in radar and space communication application.
