Abstract

This paper proposes a compact planar ultra wideband (UWB) antenna is proposed which is applicable in the field of communication, radar and medical. The proposed antenna has a low profile structure, consisting of a modified radiating patch in Asscher shape with an octagonal slot. The optimized antenna is capable of being operated in frequency range of 2-14GHz band having good omnidirectional radiation pattern and high gain, which almost satisfies the requirements of UWB applications. The antenna system has a compact size of 30×28.5×1.6mm3. These features make the proposed UWB antenna a good candidate for communication, radar and medical applications.
