A Low Profile, UWB Circular Patch Antenna with Monopole Like Radiation Characteristics
a simple ultra wideband antenna with monopolelike radiation pattern is presented in this paper. The structure of this low profile antenna with height of the 7 mm (0.65 ;min) is based on annular ring circular patch. To improve the antenna's bandwidth, the main annular ring circular patch is loaded with two concentric rings and two rectangular slots. The result shows the antenna achieves a 10 dB return loss bandwidth from 2.85 GHz to 8.6 GHz. The monopole like radiation pattern is maintained throughout the frequency bands by combining four propagation modes of TM01, TM02, and TM03.
