Aperture Coupled Beamforming Antenna Array

An aperture coupled micro strip patch antenna for V-band is designed in this paper. It consists of two substrates with slot cut ground in the between two substrates with patch at the top and feed line at the bottom of other substrate. Power is coupled from feed line through slotted ground to the patch. This antenna gives good matched results for 59 GHz to 63 GHz below -10dB and gain of maximum 14–15 dBi in for single antenna and more than 24 dBi for 16 array elements beamforming array. The beam forming of ±45 ○ is shown for channel 2 and channel 3 of IEEE 802.11ad.
