High Gain V-Antenna Array for 60 GHz WiGig Network

Abstract

: This paper provides an efficient but simple designed V-Shaped microstrip array antenna on a RT duroid substrate of dimension 50 mm× 40 mm × 1.6 mm . By considering the ratio of the length of one leg of the V-element and wavelength of the desired frequency , the angle between two legs of V-Patch has been determined . For a more efficient outcomes , an array design of 4-elements is made and its comparison with single element is done .A simple line feed technique has been used , with feedline width of 3mm .The proposed structure is simulated by using Ansys HFSS software and S-Parameter , antenna gain , directivity, Standing wave ratio and surface current distribution have been determined .Unlike conventional patches, the array contains a separation between two consecutive V-Elements in the shape of a rectangular patch termed as element separation band (ESB ) and it plays an important role in modifying the antenna gain and directivity. This antenna produces a return loss of -39.387 dB at 60.58 GHz frequency to cater the present demand of 60 GHz Wi-Gig and WPAN.
