Radiation properties of air gap Hexagonal Patch Microstripantenna (HPMA)

Sandhya Mann


The microstrip antenna with an air gap was introduced by Lee and Dahele and has been investigated for HPMA. The antenna consists of a hexagonal patch where an air gap also exists between the ground plane and the substrate below the hexagonal patch radiator. The recent years have seen a huge development in low cost compact antennas for communications purpose. This is where the microstrip antenna shines due to its light weight and compact size and capable of giving good radiation characteristics over a wide range of frequencies. We have investigated HPMA for various radiation characteristics at two operating frequencies in S and X band range.
