Microstrip Patch Antenna for Wi-Fi Application

The book describes the different feeding techniques for wireless microstrip antennas, which are microstrip line feed, coaxial plane feed, proximity coupled feed, and aperture coupled feed. Microstrip line and coaxial probe feeds are contacting scheme, in which RF power directly to the radiating patch using a connecting element such as a microstrip line where proximity and aperture coupled feeds are non-contacting schemes, in which electromagnetic field coupling is done to transfer power between the microstrip line and the radiating patch and gives a better understanding of design parameters of an antenna and their effect on return losses, bandwidth, VSWR and resonant frequency.
