Abstract
This paper focuses on comparison between coplanar Vivaldi antenna, Antipodal Vivaldi Antenna (AVA) and Balance Antipodal Vivaldi Antenna (BAVA) on FR4 substrate, in the same size and type of substrate and the same opening rate of the exponential taper. The proposed antenna has overall size 1.1λ × λ × 0.016λ and works in 2-4 GHz. The best return loss has been obtained for BAVA of -47 dB at 2.374 GHz from simulated result. For overall of frequency, coplanar vivaldi antenna gets higher gain than AVA and BAVA. Directivity of coplanar Vivaldi is 7.859 dBi at 4 GHz. AVA has more asymmetric radiation pattern than BAVA. Side lobe level for coplanar Vivaldi antenna has better performance than AVA and BAVA.
