Abstract—A novel ultra wideband (UWB) multiple-input-multiple-output (MIMO) antenna with different polarizations and band-notch characteristics is proposed in this letter. The antenna consists of two monopole antenna radiating elements with gradual change structure, which are placed perpendicularly to each other and printed on each side of the substrate to achieve a wide bandwidth and different...

The design and development of Ultra Wide Band (UWB) antenna on silicon substrate is presented in this article. Planar monopole antenna having circular radiating patch, excited with 50 ? co-planar waveguide transmission line is chosen here. Slots are incorporated in the radiation patch to achieve band-notch characteristics at two distinct bands for WiMAX (3-4 GHz) and WLAN (5-6 GHz) applications...

© 2013 Jung-Nam Lee et al. 1075 http://dx.doi.org/10.4218/etrij.13.0113.0472 This paper describes an ultra-wideband (UWB) antenna that uses a ring resonator concept. The proposed antenna can operate in the entire UWB, and the IEEE 802.11a frequency band can be rejected by inserting a notch stub into the ring resonator. The experiment results indicate that the measured impedance bandwidth of the...

This study presents new antenna schemes suitable for cognitive radio communications. The antenna structures consist of a ultra wide band (UWB) sensing antenna, and a frequency reconfigurable communicating antenna both incorporated into the same substrate. Two different techniques to achieve the required frequency agility are proposed. The first one is based on a rotational motion of the radiati...

A coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna with dual notched band characteristics is presented in this paper. The circular wide slot and circular radiation patch are utilized to broaden the impedance bandwidth of the UWB antenna. The dual notched band functions are achieved by employing two stepped impedance resonators (SIRs) which etched on the circular radiation patch and CPW...

In this paper, a novel compact butterfly shaped printed monopole antenna for ultra-wideband (UWB) applications is presented.

The antenna prototype is designed then fabricated and tested experimentally. The calculated impedance bandwidth of the proposed a...

Ultra wideband (UWB) technology based on the use of very narrow pulses on the order of nanoseconds, covering a very wide bandwidth in the frequency domain, is one of the most promising solutions for future communication systems due to its high-speed data rate and excellent immunity to multipath interference. In this context, the antenna is one of the important components which determine the per...

This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of th...

Abstract—An ultra wideband (UWB) coplanar waveguide (CPW) fed rectangular monopole antenna, which is of band notched characteristic for Wireless Local Area Network (WLAN), Worldwide inter-operability for Microwave Access (WiMAX) and the C-band satellite communications, is proposed, fabricated and measured. In order to obtain the desired dual band rejections, a piece of pentagonal slotline and a...
