Design of a Compact UWB Planar Antenna with Band-Notch Characterization

In this paper, a slot loaded ultra wideband monopole patch antenna with triple band‐notched characteristic has been presented. The antenna consists of rectangular patch with three modified inverted U‐shaped slots to create three notches at Wi‐MAX (3.3–3.6 GHz), C‐band (3.7–4.2 GHz), and WLAN (5.15–5.85 GHz) frequencies. Lumped‐element equivalent circuit model and current distribution curves have been used to explain the triple band‐rejection characteristics of the designed antenna. The proposed triple notch structure has been fabricated and tested against simulated data. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:138–142, 2017

“…The lengths of the slots at the center frequency of the notched bands have been calculated by following equation .

L_{eff} = \frac{0.45 C}{f_{notch} \sqrt{\frac{(ε_{r} + 1)}{2}}}

This article presents the design of a compact, low‐profile planar antenna with a circular radiator. With careful design of the radiator and ground plane, the antenna's low‐frequency range extends to 1.5 GHz, in addition to operating as an ultrawideband (UWB) antenna across the entire Federal Communications Commission allocated UWB range. © 2016 Wiley Periodicals, Inc.

“…Notwithstanding the advantages of UWB their transmitters should not cause any electromagnetic interference to nearby communication system such as the wireless local area network (WLAN) applications due to this cause, avoid interfering with nearby communication systems such as IEEE 802.11a in the U.S. (5.15–5.35 GHz, 5.725–5.825 GHz) UWB antennas with band‐notched characteristics in the WLAN frequency band are mandatory. Some papers studied effect of coupling between the feed line and the aperture by using different shape of radiating patch (i.e., circular, elliptical, hat‐shaped, arc‐shaped slot) and their feed lines . A CPW‐fed monopole antenna with a band‐botch function was presented in with square slot and sharp edge structure for UWB applications.…”

A circular slot CPW‐fed monopole antenna for ultrawideband (UWB) applications, with a size of (22 × 22 mm2) is presented in this article. The antenna is mounted on FR4 substrate. This antenna is designed for operation across the entire UWB from 3 to 16 GHz. The proposed antenna has a reflection coefficient below −10 dB through the frequency band. Details of the proposed antenna and experimental results are discussed and parametric study is presented. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1773–1776, 2014
