Phased Array Antenna, RCS, SATCOM, VSWR


The present paper discusses the design, analysis, and development of a low profile, low RCS, diagonally polarized and wide beam
radiating element at Ku-Band for Electronically Steered Phased Array Antenna (ESPAA) for airborne applications. Radar Cross Section (RCS) of the antenna has been minimized by proper selection of substrate and eliminating the diffraction and scattering of the incident wave through the antenna. Finite element method (FEM) based full wave ANSYS's HFSS EM Simulation software was used for simulation and optimization of the antenna. The measured half power beam width of the antenna element is 90 degree and RCS better than -30 dBsm over the wide angular coverage of radiating element.
