A U-Shaped Slot UWB Antenna with Flexible and Wide Tunable Dual Notch Band

Blog Article

A coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna Calendula with flexible and wide tunable dual bandnotched characteristics is proposed in this paper.The dual band-notched function is achieved by using an U-shaped slot inserted into the ellipse radiation patch and by using an elliptic parasitic slit placed near the ground plane.The wide tunable band-notched characteristic is implemented by adjusting the length of U-shaped slot and by adjusting the length of ellipse parasitic slit.

The design aims to achieve wide reconfigurable band-notched features on the UWB antenna.The simulated results indicate Pre-Workout that the proposed antenna has a wide bandwidth (VSWR under 2) from 2.9GHz to 12.

6GHz with fractional bandwidth of 125%, and has a wide tunable notch band center frequency from 4.5GHz to 12.4GHz.
