Design of Butterfly modeled patch in Hexagonal Conformal Array Antenna for SAR Applications

Abstract

In this work, a novel approach for the simulation of hexagonal conformal array (HCA) antenna design is produced and presented for X band applications. The array elements are embedded on FR-4 substrate with low profile having dimensions of $65\times 65\text{mm}$. The proposed conformal antenna is designed to resonate at 10 GHz with an impedance bandwidth of 300MHz (9.88GHz to 10.18GHz). This antenna array resonates at the same frequency as the single element but with increased gain and having omni-directional radiation pattern. This omni directional nature of the array is advantageous to receive signals equally from all directions. This antenna array can be utilized for SAR applications.
