A Low Profile UWB Antenna with Triple Band Suppression Characteristics
The proposed triple band notch antenna is a coplanar waveguide fed radiator with incorporated notching resonators etched for achieving the desired band rejection. Sequential design of UWB antenna is presented for different frequency band rejections. Three different notch antennas are proposed having single band rejection for each antenna. The optimized antenna is achieved by accumulating the three stop band resonators in a single design. The mutual coupling effect of the proposed resonators are investigated in details. Proposed antenna operates from 2.4 to 11GHz. The introduction of C-shape slot at main radiator, CSRR at ground plane and inverted U-shape slot at the center of the patch results in narrow band rejection of WiMax (3.5GHz), WLAN (5.8GHz) and satellite service band (8.2GHz), respectively. The antenna prototype measures \(31 \times 30\,\hbox {mm}^2\). Measured and simulated results fulfil the performance criteria for the proposed antenna.
