Design of a compact band notched antenna for ultrawideband communication /
This research work focuses on analysis and design of a compact printed band-notched antenna for UWB communications. The proposed antenna is designed to cover the FCC bandwidth for UWB applications (3.1–10.6GHz) with band-notched at frequency band (5.15–5.825GHz). The proposed antenna is fed by micro...

| 520 | |a This research work focuses on analysis and design of a compact printed band-notched antenna for UWB communications. The proposed antenna is designed to cover the FCC bandwidth for UWB applications (3.1–10.6GHz) with band-notched at frequency band (5.15–5.825GHz). The proposed antenna is fed by microstrip line, and it consists of square radiating patch with three steps and a W-shaped slot on the top layer with a slotted-parasitic patch on the bottom layer of the antenna. The slotted-parasitic patch acts as a notch filtering element to reject the frequency band (5.15–5.825GHz) which is used by IEEE 802.11a and HIPERLAN/2. The proposed antenna structure is simulated in order to obtain the return loss, the gain, and the radiation efficiency of the antenna, using the commercial electromagnetic (EM) simulators; CST Microwave Studio and HFSS. Furthermore, parametric studies on the return loss have been carried out in order to obtain the optimal dimensions for the proposed antenna. The performances of the proposed antenna are investigated in both frequency domain and time domain. Moreover, the pulse distortions of different input pulses are investigated based on S21 parameters for two different orientations (face to face and side by side). There is a small acceptable influence on the matching between the input and the output pulses and it is found that the pulse distortion is low. The studies also show that high signal fidelity is achieved for all input signals. In order to verify the simulated results, the proposed antenna had been fabricated. The measured result for the return loss of the proposed antenna shows that the antenna has operating frequency bandwidth from 2.92–10.75GHz and notched frequency at 5.16–5.95GHz. Therefore, it is demonstrated numerically and experimentally that the antenna is a good candidate for UWB applications. | ||
