A novel band-notched ultra wide-band antenna with a coplanar parasitic elliptical patch in an elliptical ring is presented in this paper. Printed on a dielectric substrate of FR4 with relative permittivity of 4.4 and fed by a 50 Omega microstrip line, the proposed monopole antenna demonstrate a 10 dB return loss bandwidth of 2.91-11.91 GHz, with a band-notched at 5.15-5.98 GHz band and good radiation patterns. The proposed antenna is utilize the coplanar parasitic elliptical patch to reject the frequency band (5.15-5.85 GHz) limited by IEEE802.11a and HIPERLAN/2. The parameters which affect the performance of the antenna in terms of its frequency domain characteristics are investigated in this paper.
