Microstrip Antenna Array for Beamforming Systems

A dual and quad element antenna array resonating at 2.4 GHz with narrow beam is proposed in this paper. An intention to put forward this work is to make use of microstrip patch antennas in beamforming to form directional beams in analog and digital domains; reducing co-channel / multipath interferences and improving Quality of Service (QoS) for senor arrays and 3G wireless networks. The size of dual and quad element antenna array is 60 x 130 mm2 and 60 x 240 mm2 respectively. Simulations in HFSS (High Frequency Structure Simulator) showed least mutual coupling among adjacent elements and prototypes have been fabricated using FR4 to verify the efficiency of the presented work for IEEE 802.11b/g WLAN standards.
