Gain enhancement of microstrip antenna using a novel dielectric loading technique

In this paper, gain enhancement of Microstrip Antenna (MSA) using dielectric loading and array of metallic rods is presented. The substrate and dielectric load are made up of silicone rubber which has measured dielectric constant of 5.01 at 1GHz. The designed dielectric loaded antenna with an array of metallic rods shows significant gain improvement of around 6dB, as compared to simple patch antenna. The designed antenna structure provides gain of around lOdB. VSWR is less than 2 in desired frequency band and radiation pattern is directive. The resonant frequency is 24.35GHz. The proposed antenna can be used in point to point wireless systems.
