This antenna has beam switching capability at different angles. Progressive phase shift is provided through 3dB branch line coupler.

To increase the bandwidth of microstrip patch antenna different feeding mechanism are used one is aperture coupled feeding. This antenna has aperture in ground plane and patch is coupled through this aperture to the feed.
Aperture Coupled Microstrip Antenna

Generally, patch antennas are narrow band so there are many techniques and methods to enhance the bandwidth of patch antennas like using thicker substrate, wideband feeding mechanism or use artificial magnetic conductor (AMC), frequency selective surfaces and metamaterials etc. One way is to use different feeding techniques like edge feed patch antenna is narrow band, to enhance its bandwidth one can use feeding techniques like proximity coupled feeding or aperture coupled feeding whereas design challenges are multilayer structure and optimization of slots and feeds dimensions for impedance matching. This antenna design has improved better fractional bandwidth of 29%. Antenna is Designed and simulated on HFSS and CST.
