| Abstract | ||
| A coplanar waveguide (CPW) fed printed monopole ultra-wideband antenna with E-shaped notched band slot is presented. This antenna is fed by a 50 ohm CPW line and it is fabricated on the FR-4 substrate with a thickness of 1.5 mm and relative dielectric constant of 4.4. Two modifications are introduced on this antenna to improve its operating bandwidth. The first one is to remove a 90o angles from the two upper corners of the ground plane by blending them in a radius of 10mm. The second modification is to chamfer the feed edges at the patch. All simulations in this work were carried out by using CST Microwave StudioTM package. Compared with the recently proposed antennas, the proposed antenna has wide bandwidth with acceptable returned losses, compact in size and easy design, easy controllable band-notch characteristics and good gain characteristics over the entire desired bandwidth. | ||
