Abstract
The design of a planar phased array composing of 12 linear subarrays in the vertical plane has been investigated in this paper. Each linear in-phase subarray consists of 24 compact stripline-fed antennas in the horizontal plane. The proposed linear subarray is fed by a 24-port parallel feeding network where amplitudes at the output ports are controlled by a Taylor distribution with sidelobe level of -36 dB. The planar array has been fabricated and measured in the frequency band from 3.2 – 3.6 GHz. The simulation and measurement results show a good agreement and the planar phased array is adapted to the requirements for 3D radar application.
