Abstract
Aims: 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. Objective: 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. Methods: 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. Results: 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. Conclusion: 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.
