Abstract :
Super Wideband (SWB) printed antenna with enhanced gain covering the impedance bandwidth ranging from 3-20GHz is presented. Gain enhancement of the antenna is achieved using appropriately designed frequency selective structure (FSS) acting as a band stop filter i.e. reflector, while keeping the bandwidth of antenna unchanged. The FSS used effectively reflects the in-phase radiations with a very low transmission coefficient over the entire bandwidth which is key requirement for providing antenna gain enhancement for wide frequency range. Hence significant improvement in antenna gain has been achieved using low profile and without compromising the impedance bandwidth. Results show a significant improvement in gain (i.e. 4-5dB) over the whole frequency range.
