“…In the proposed design, based on electromagnetic coupling theory (ECT), by using an inverted protruded T‐shaped strip and also by adding a pair of T‐shaped conductor‐backed plane at gap distance in the ground plane, much wider impedance bandwidth can be produced . Also by converting a square radiating to the pair of coupled U‐ring structure, a good dual frequency band‐notched function can be achieved .…”

“…There are many narrowband communication systems which severely interfere with the UWB communication system, such as the wireless local area network (WLAN) for IEEE 802.11a operating in 5.15–5.35 and 5.725–5.825 GHz bands, WiMAX (3.3–3.7 GHz) and C‐band (3.7–4.2 GHz) or downlink of X‐band satellite communication (7.25–7.75 GHz). Therefore, UWB antennas with band‐notched characteristics to filter the potential interference are desirable .…”

In this manuscript, a new design of ultra-wideband (UWB) monopole antenna with dual band-stop performance is proposed. The configuration of the antenna consists of a pair of coupled U-ring structures as a radiating patch, and a modified ground plane with inverted T-shaped strip and a pair of T-shaped conductor-backed plane. In the presented structure, by using an inverted T-shaped strip and also by embedding a pair of T-shaped parasitic structures in the ground plane, additional resonances at the higher band are excited which provides a wide usable fractional bandwidth of more than 135%. In order to generate single and dual band-notched characteristics, we convert the square radiating to the pair of coupled U-ring structures. The measured results reveal that the presented dual band-notched monopole antenna design exhibits an operating bandwidth (VSWR < 2) form 2.81 GHz to 15.12 GHz with two notched bands, covering the 5.2/5.8 GHz, 3.5/5.5 GHz, 4 GHz to suppress interferences from wireless local area network (WLAN), worldwide interoperability microwave access (WiMAX), and C-band systems, respectively. Good return loss, antenna gain, and radiation pattern characteristics are obtained in the frequency band of interest. The configuration of the proposed monopole antenna is simple, easy to fabricate, and can be integrated into any UWB system.

This article presents a new design of ultrawideband (UWB) microstrip slot antenna with band‐notched function around 5–6 GHz to avoid any interference from the wireless local area network (WLAN) systems. The proposed antenna consists of a square radiating stub with a rotated C‐ring slot, a feed‐line and a slotted ground plane with an S‐shaped parasitic structure inside an extra rectangular slot. By cutting a rectangular slot on top of the ground plane and also by embedding an S‐shaped parasitic structure inside the slot, a new resonance at the higher frequencies is excited and hence much wider impedance bandwidth can be produced, which provides a wide usable fractional bandwidth of more than 135%. In the proposed design, to generate the WLAN band‐stop property, the rotated C‐ring slot was inserted at the radiating stub. Simulated and measured results are presented to validate the usefulness of the proposed antenna structure for UWB applications. The proposed monopole antenna configuration is simple, easy to fabricate and has a small size of 20 × 20 × 0.8 m3. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1744–1747, 2014

Ultra‐wideband technology has experienced a rapid growth over the last decade for its contribution in different sectors of human society. Printed antennas are considered as preferred platform for implementing this technology because of its alluring characteristics like light weight, low cost, ease of fabrication, integration capability with other systems, etc. Antennas developed for ultra‐wideband applications are desired to have notch characteristics for avoiding interference with other existing radio communication systems. The techniques related to design and developments of printed band‐notched antennas are continuously upgraded for improving the antenna performance. In this article, a comprehensive review has been carried out on ultra‐wideband antennas with band notch characteristics proposed in around last decade. The band notched UWB antennas available in the literature have broadly been classified into five different categories based on their notch characteristics like single band‐notch, dual band‐notch, triple band‐notch, quad/multiple band‐notch, and reconfigurable/tunable band‐notch, respectively. This review exercise may be helpful for beginners working on ultra‐wideband band‐notched antennas and also such a review process is not available in the open literature to the best of author's knowledge.
