Abstract:
A method of manufacturing a phased array antenna used to transmit/receive an RF signal having a beam direction adjustable by controlling a phase of the RF signal transmitted/received by each radiation element, comprising the steps of:patterning, by photolithography and etching, a phase control layer with plural phase shifting units, each phase shifting unit connected to a control signal line connecting to a signal driver, a control scanning line connecting to a scanning line selector, a first strip line connecting to a distribution/synthesis unit, and a second strip line connecting to a radiating element, the first strip line being connected to the second strip line via the phase shifting unit; and patterning, by photolithography and etching, a radiating element layer, the radiating element layer comprising plural radiation elements operatively connected via the second strip lines to corresponding ones of the phase shifting units for controlling the phase of the RF signal transmitted/received to/from each radiation element, the phase control layer and the radiating element layer forming stacked layers; and bonding the stacked layers to each other, wherein all of the phase shifting units are simultaneously formed.
