Abstract
In this paper, a multi-layer antenna with high gain and wide bandwidth for 60 GHz Millimeter wave (MMW) applications is presented. The proposed antenna is a combination of aperture coupled microstrip patch antenna with an integrated Horn mounted on FR-4 substrate. The maximum size of the proposed antenna is 7.14mm x 7.14mm x 4mm. The design is optimized by means of parametric-variation. Investigations are made on the physical parameters of the proposed design by optimization, in order to achieve wide band and high gain millimeter wave antenna structure. The S11 bandwidth of the optimized antenna is 8.3% (57.4 - 62.4 GHz). The maximum gain and directivity of the proposed antenna is 11.65 dBi and 12.51 dBi respectively. The estimated efficiency is 82%. The proposed antenna finds application in V-band communication systems.
