Abstract
In this paper, a smart beam steering technique is investigated with a miniaturized patch antenna at 2.45 GHz. The antenna is miniaturized with an asymmetrically placed slot on the patch that reduces the frequency of operation significantly. It radiates with $23 \%$ area $(0.15 \lambda X 0.11 \lambda, \lambda$ is the freespace wavelength at 2.45 GHz) of a conventional patch at the operating frequency with the same dielectric properties. A $1 \times 8$ antenna array is also designed with a power divider and phase shifter circuit to demonstrate a beam steering operation. With numerical investigation, a maximum of 220 steering angle is observed in the azimuthal plane.
