Abstract

A simple method for designing of a compact planar antenna featuring ultra wideband performance and simultaneous signal rejection over a narrow sub-band is presented. This design is demonstrated when substrate is assumed in the form of low temperature cofired ceramic (LTCC). Results of simulations show that the designed antenna of 30 mmtimes 24 mm dimensions supported by DuPont951 ground plane of 1 mm thickness has a 10-dB return loss bandwidth from 2.6 GHz to more than 10 GHz excluding the 4.9-5.9 GHz rejection sub-band assigned for IEEE 802.11a and HIPERLAN/2. This sub-band rejection is obtained using a tuning slot. The antenna has near omnidirectional characteristics. Its radiation efficiency is higher than 91% over the whole pass-band
