Printed triple‐band rectangular ring monopole antenna with symmetrical L‐strips for WLAN/WiMAX applications

A novel compact microstrip‐fed tri‐band monopole antenna for WLAN and WiMAX applications is presented in this letter. Hybrid Strips including an L‐shaped strip and a meandered strip are used to generate three resonances in the monopole antenna. Due to the use of a meandered line structure, the antenna size is reduced to 38 × 20 × 1 mm3 only. Compared to the existing designs, the proposed antenna has a size 30, 55, and 70% of the designs in [1–3], respectively. To investigate the performance of antenna versus key antenna design parameters, results of a parametric study are presented. Simulated surface current is also shown. To validate the concept, one antenna prototype is implemented and tested, and the measured results show that the antenna can achieve good performance for WLAN 2.4/5.8 GHz and WiMAX 3.5 GHz applications. The antenna has a compact size and is easy for fabrication, hence useful for practical applications. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:94–99, 2015

2014

In this article, a novel triple‐band‐modified three‐circular‐ring monopole antenna with a rectangular slot in the ground plane for wireless local area network (WLAN)/worldwide interoperability of microwave access (WiMAX) applications is proposed. The proposed antenna consists of two circular rings and one open‐ended circular ring. Based on the concept, a prototype of the proposed triple‐band antenna was designed, fabricated, and tested. The numerical and experimental results demonstrated that the proposed antenna satisfied the −10‐dB return loss for impedance bandwidth requirement while simultaneously covering the WLAN and WiMAX bands. Furthermore, this article presents and discusses the two‐dimensional radiation patterns and gains according to the results of the experiment. © 2014 Wiley Periodicals, Inc.

Fabrication and measurement of a monopole antenna with three arc‐shaped strips for WLAN/WiMAX applications

2014

In this article, a novel, compact, printed antenna is applied to simultaneous wireless local area network (WLAN)/Worldwide Interoperability of Microwave Access (WiMAX) applications. The proposed antenna is composed of three arc‐shaped monopole strips and a rectangular ground plane. The three arc‐shaped strips of the antenna generate three desired resonate frequencies and exhibit relative independence while being tuned separately. Based on the concept, a prototype of the proposed triple‐band antenna is designed, fabricated, and tested. The numerical and experiment results demonstrated that the proposed antenna satisfied the −10 dB impedance bandwidth requirement (467.5 MHz for the 2.4/2.5 GHz bands, from 2.23 to 2.6975 GHz; 857.5 MHz for the 3.5 GHz bands, from 3.3975 to 4.255 GHz; 2,012.5 MHz for the 5 GHz bands, from 5.06 to 7.0725 GHz), while simultaneously covering the WLAN and WiMAX bands. The proposed triple band antenna achieves omnidirectional radiation patterns at all three frequency bands with an antenna peak gain of 4.68 dBi for the lowest band, 2.74 dBi for the middle band, and 3.11 dBi for the highest band. © 2014 Wiley Periodicals, Inc.
