Printed Angled Dipole Linear Array Antenna with 1:32 Un-Equal Power Combiner for X-Band Phased Array Radar Application

A 32-element printed Angled dipole array antenna with unequal power division feed network for X-band phased array application presented. A printed angled dipole antenna (PADA) as a radiating element designed with a modified parasitic cap in front of the dipole aperture to control the beam width over the operating frequency range. The 32-element array is designed along with a 1:32-way power divider. The power divider employed corporate feed with an un-equal power division based on Taylor distribution to achieve 30dB side lobe level. The proposed linear array antenna achieved a peak gain of 19dB. The Antenna Array simulated using Ansys High-Frequency Structure Simulator (HFSS), a Finite Element Method (FEM) solver. Stripline to microstrip transition incorporated at the Power divider input port for easy fabrication. The proposed model is validated through measurements.
