Design and study of a CPW fed truncated circular patch switchable band-notched UWB antenna

Abstract

A reconfigurable Ultra Wideband antenna is developed and presented in this paper. The proposed antenna has the dimension of 32x36x1.6mm3and shows its compactness. In this design, a pair of J-shaped slots combined together in the radiator of the antenna. The proposed antenna has the UWB range from 3.1-10.6GHz and extends up to 13GHz. Later, a study is conducted to apprehend the switching behavior of the antenna when the switching elements are incorporated in the combined J-shaped slot in parallel mode. The switching elements we used in this paper are PIN diodes (BAR64-02V). The switching conditions of the proposed antenna yields the frequency reconfigurable for notch band nature among the spectrum that covers WLAN and UWB which shows the compatible use in IoT devices.
