Abstract

In this communication, a new compact UWB monopole antenna with dual band rejection is presented. The antenna is designed using FR4 substrate with dielectric constant 4.4, loss tangent 0.02 and a height of 1.59 mm. Initially the UWB antenna is designed to obtain a 153% fractional bandwidth from 2.4 GHz-21.7 GHz. The ground plane beneath the patch is etched out and a rectangular slot is introduced to obtain a broadband matching over the operating frequency range. Later the antenna is modified to get a frequency notch in the IEEE802.11a and HIPERLAN/2 WLAN operating band (5.15 GHz-5.825 GHz) to avoid potential interference. A U shaped slot is optimally introduced in the patch to get the desired performance. Finally an L shaped slot is cut from the radiating patch to filter the frequency band 3.3 GHz-3.6 GHz, which is WiMAX service band. The antenna parameters are optimized and the effects of parametric variation on antennas performance are studied and the summary is presented. The antenna is fabricated and measured results are presented. The measured results are in well agreement with the simulated results.
