Design of Reflectarray Vertical Stubs Antenna with Beamforming for WiGig Applications

High data rates and fast transmission are indispensable for wireless telecommunications. IEEE 802.11 allocates frequency bands of 57 - 64 GHz for the Wireless Gigabit (WiGig) applications. Antennas with high gain that support high frequency are urgently needed. Reflectarray antenna is considered to fulfill the requirements due to each element of the array scatters the incident waves with a certain phase shift to compensate for the different spatial lengths of the feed to create coherent radiation in the desired direction. Moreover, the beamforming technique is counted to obtain a directional signal transmission. This paper proposes a reflectarray antenna operating at 60 GHz. The reflector antenna unit cell model consists of a square patch and a cross patch with the addition of stubs. A complete reflectarray consists of 7 × 7-unit cells in a square of 35 mm array form. The simulation results show a gain of 15.88 dBi with a beamforming of 60°.
