This paper introduces a compact dual notched UWB antenna with an independently controllable WLAN notched band integrated with fixed WiMAX band-notch. The proposed antenna utilizes a slot resonator placed in the main radiator of the antenna for fixed WiMAX band notch, while an inverted L-shaped resonator in the partial ground plane for achieving frequency agility within WLAN notched band. The inverted L-shaped resonator is also loaded with fixed and variable capacitors to control and adjust the WLAN notch. The WLAN notched band can be controlled independently with a wide range of tunability without disturbing the WiMAX band-notch performance. Step by step design approach of the proposed antenna is discussed and the corresponding mathematical analysis of the proposed resonators are provided in both cases. Simulation of the proposed antenna is performed utilizing commercially available 3D-EM simulator, Ansoft High Frequency Structure Simulator (HFSS). The proposed antenna has high selectivity with experimental validation in terms of reflection coefficient, radiation characteristics, antenna gain, and percentage radiation efficiency. The corresponding measured frequency response of the input port corresponds quite well with the calculations and simulations in both cases. The proposed antenna is advantageous and can adjust according to the device requirements and be one of the attractive candidates for overlay cognitive radio UWB applications and URLLC service in 5G tactile internet. The proposed multi-functional antenna can also be used for wireless vital signs monitoring, sensing applications, and microwave imaging techniques.
