Microstrip Monopole Antenna

In this research article, a simple and compact dual-band microstrip monopole antenna is discussed. A CPW feed is given to patch consisting of rectangular coplanar ground sheets on either side, truncated their centers with smaller rectangular sheets giving the shape of rectangular rings. The proposed antenna is designed using FR4 epoxy substrate having dielectric constant 4.4 and thickness 1.6mm. The main element in the antenna is four inverted L shaped stubs which govern the impedance bandwidth of the antenna. Simulations are carried out using HFSS software. The S11 plot for the proposed antenna showed dual-band characteristics with a lower band ranging from 1.09GHz to 2.33 GHz (1.24 GHz bandwidth) and the upper band covering 3.01 GHz to 10.738 GHz (7.728 GHz bandwidth). The proposed antenna bandwidth ranges of the proposed antenna will be covering the GPS, PCS and UMTS applications for lower band and UWB applications for upper band. The antenna exhibited a peak of 3.01 dB and 4.54 dB at 1.89 GHz and 9.45 GHz. Simulations are carried and all the important findings are plotted.

A meandered-microstrip fed circular shaped monopole antenna loaded with vertical slots on a high dielectric material substrate(εr=15)is proposed in this paper. The performance criteria of the proposed antenna have been experimentally verified by fabricating a printed prototype. The experimental results show that the proposed antenna has achieved wider bandwidth with satisfactory gain by introducing meandered-microstrip feeding in assistant of partial ground plane. It is observed that, the −10 dB impedance bandwidth of the proposed antenna at lower band is 44.4% (600 MHz–1 GHz) and at upper band is 28% (2.25 GHz–2.95 GHz). The measured maximum gains of −1.18 dBi and 4.87 dBi with maximum radiation efficiencies have been observed at lower band and upper band, respectively. The antenna configuration and parametric study have been carried out with the help of commercially available computer-aided EM simulator, and a good accordance is perceived in between the simulated and measured results. The analysis of performance criteria and almost consistent radiation pattern make the proposed antenna a suitable candidate for UHF RFID, WiMAX, and WLAN applications.

Simulation Results

In the present work, a novel multistrip monopole antenna fed by a cross-shaped stripline comprising one vertical and two horizontal strips has been proposed for wireless local area network (WLAN)/Industrial, Scientific, and Medical band (ISM)/International Mobile Telecommunication (IMT)/BLUETOOTH/Worldwide Interoperability for Microwave Access (WiMAX) applications. The designed antenna has a small overall size of 20 × 30 mm2. The goal of this paper is to use defected ground structure (DGS) in the proposed antenna design to achieve dual-band operation with appreciable impedance bandwidth at the two operating modes satisfying several communication standards simultaneously. The antenna was simulated using Computer Simulation Technology Microwave Studio (CST MWS) V9 based on the finite integration technique (FIT) with perfect boundary approximation. Finally, the proposed antenna was fabricated and some performance parameters were measured to validate against simulation results. The design procedure, parametric analysis, simulation results along with measurements for this multistrip monopole antenna using DGS operating simultaneously at WLAN (2.4/5.8 GHz), IMT (2.35 GHz), BLUETOOTH (2.45 GHz), and WiMAX (5.5 GHz) are presented.
