Abstract: A four element 2×2 antenna array has been designed and investigated for the radiolocation applications at the X-band frequency of 10GHz. Two different antenna array are been designed with two different radiating element shapes. One antenna array is having rectangular radiating element and the other antenna array is having circular radiating element. Performance comparison has been performed between the two antenna arrays in terms of various antenna parameters like return loss, VSWR, gain, radiation pattern, directivity, mutual coupling etc. Both the antennas are been designed on a low cost easily available FR4 glass epoxy substrate which is having a thickness of 1.6mm Coaxial feed has been used to excite the antenna elements and each element of the antenna array is fed by a independent coaxial feed. Commercial available 3D model simulator tool Ansys HFSS has been used to simulate the antenna array.
Keywords: Antenna Array, X-Band, Coax Feed, Mutual Coupling.
