“…There are several ways to widen the impedance bandwidth of an antenna to design an UWB antenna [8,9]. In the recent years, different antenna designs for CR application have been reported in [3,7]. An UWB and a reconfigurable narrowband antenna can be chosen to handle sensing and communication functions, respectively.…”

“…Hence, we chose the rectangular DRAs for our investigations in this paper with modified microstrip line feeding mechanism to ensure efficient coupling [2]. Good ultra-wideband (UWB) antennas for CR spectrum sensing should have low return loss, Omni-directional radiation pattern, and high efficiency over the ultra-wide bandwidth from 3.1 to 10.6 GHz [3][4][5][6]. UWB radio systems according to FCC regulation use 7.5 GHz, from 3.1 to 10.6 GHz, to transfer data.…”

In this paper, a novel compact UWB, low-profile monopole rectangular dielectric resonator antenna (RDRA) is proposed using relatively low dielectric constant substrate material (Rogers RTlDuroid 3010 Er = 10.2) and developed for cognitive radio (CR) spectrum sensing wireless communications applications. The rectangular DRA is fed with a modified stepped microstrip feed to ensure efficient coupling between the RDR and the feeder. UWB operation is achieved by converting RDRA to monopole RDRA by finite ground plane which leads to a wider operating bandwidth. The proposed UWB monopole RDRA with finite ground plane produced an impedance bandwidth about 141 % covering a huge band for CR spectrum sensing. The proposed antenna is designed to operate over a frequency range from 3.1 to 18 GHz and the radiation patterns are stable over the operating frequency range. The frequency characteristics and radiation performance of the proposed antenna are successfully optimized with numerical experimentation techniques using 3D full-wave electromagnetic simulator Ansoft HFSS. Moreover, the proposed design is implemented using three dimensional finite difference time domain (FDTD) method for verification purposes. The obtained FDTD and simulation results are in good agreement.Index Terms-Monopole RDRA (rectangular dielectric resonator antenna); UWB (ultra wide band); cognitive radio(CR}; finite diff erence time domain (FDTD)

Abstract-In this paper, an ultra-wideband (UWB) conformal monopole antenna integrated with a narrow-band (NB) rectangular slot antenna is designed and fabricated. The proposed structure consists of a circular disc monopole antenna printed on a cylindrical surface and fed by a coplanar waveguide line (CPW). A rectangular slot antenna, excited by a microstrip line, is integrated in the front of the UWB antenna. The simulations are performed using the CST Microwave Studio software. To validate the proposed antenna concept, an experimental prototype is fabricated and measured. The measured results show that the monopole antenna covers an ultra wideband from 2 GHz to 12 GHz with S 11 < −10 dB and provides a very good isolation with a transmission coefficient below −20 dB across the operating band. Compared to planar integrated antennas, the proposed conformed structure possesses an important wideband, which can be used in many wearable electronic applications and communication systems.

“…For this purpose, multi-band antenna designs have been proposed with various configurations [2]. The printed monopole antennas with coplanar waveguide (CPW) feeding mechanism have become very important to researchers for their advantages, such as less dispersion, easy implementation of shunt circuits, absence of via holes [3], and ease of integration with active devices or monolithic microwave integrated circuits (MMIC) [1][2][3][4].…”

Abstract-In this letter, a new coplanar waveguide (CPW)-fed monopole antenna with equilateraltriangular shape is presented and experimentally investigated. The structure under study generates three different center frequencies corresponding to the lower, middle, and upper bands for Wireless Local Area Networks (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. The proposed antenna is analyzed using the Computer Simulation Technology (CST) Software. To validate the simulation results, an experimental prototype of the proposed design is fabricated, tested and measured. The experimental results show a good agreement with the simulated ones.
