Abstract

This paper mainly deals with simulation and fabrication of liquid crystal phased array. The final design comprises of a 8×8 array, which is able to scan in one plane. Liquid crystal polymers play a major role in present research areas, which provides very reliable high performance circuits at low cost. These are flexible, recyclable and are stable up to its high melting temperature making an ideal choice for circuits operating all kinds of environments. As it is phased array antenna, it combines number of radiation patterns and so it reinforces the radiation pattern in a desired direction and suppresses in undesired direction. This antenna is a narrow band antenna and specifically designed to work for a particular frequency. The antenna is simulated using HFSS software for measuring directivity, high gain and scattering coefficients.
