Dual‐Band Monopole Antenna with Compact Radiator for 2.4/3.5 GHz WiMAX Applications

Abstract

The article presents the design of a compact dual‐band monopole antenna with microstrip‐fed for use in wireless devices in the worldwide interoperability for microwave access (WiMAX) system. The radiator of the antenna has a compact size of only 14.5 × 8.7 mm2 and consists of a short stem and two branches generating two frequency bands at around 2.4 and 3.5 GHz for the WiMAX system. The two frequency bands can be easily and independently set using the parameters of the two radiating branches. The antenna performance in terms of reflection coefficient, radiation pattern, peak gain, and efficiency is studied using computer simulation. For verification of simulation results, the antenna is fabricated and measured using the antenna measurement system Satimo Starlab. The feeding cable used to connect the antenna to the measurement system causes substantial discrepancies between the simulated and measured results. To study the cable effects, the feeding cable is modeled and used in computer simulation for studies. With the use of the cable model, the simulated and measured results agree very well. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:1765–1770, 2013

Dual Band E and L Shaped Antenna Design with Compact Radiator for 2.5/5.2/5.8 GHz WLAN Application- A Review

“…Various procedures have been introduced to decrease the size of the monopole accountable for the lower band. For example, in [1]- [3], the monopoles accountable for the lower band were bent to various shapes for size reduction.…”

“…In base Paper and supporting paper [1][2][3] is used normal optimized method. Paper [2][3][4] is using 1.6mm height and efficiency is poor.…”

“…The above techniques have been successfully used in many applications on communication. Dual band antenna with compact radiator for 2.4/5.2/5.8 GHz WLAN application design and radiator size only width 8mm and length is 11.3 mm [1]. The antenna can we used for various application in field of communication.…”

A Dual-Band High Gain Antenna Based on Split Ring Resonators and Corrugated Plate

“…In the last few years, the wireless communication system has been improved rapidly, and multi-frequency antennas with high-performance are needed to meet the requirement [1,2]. Great attention has been paid to the metamaterials, especially split ring resonators (SRRs), because of their specific properties which have not been discovered in nature [3,4].…”

Design Simulation and Fabrication of a Dual Band Frequency Reconfigurable Monopole Antenna for Wi-Fi and WiMAX Applications

“…Consequently, the antenna can cover the 2.4/5.2/5.8 GHz WLAN and 2.5/3.5/5.5 GHz WiMAX bands with a very compact size. In [12], design of a dual-band monopole antenna with microstrip fed for use in wireless devices in the WiMAX system is presented. The antenna radiator has a compact size of only 14.5 × 8.7 mm 2 and consists of a short stem and two branches resonating at around 2.4 GHz and 3.5 GHz for the WLAN and WiMAX bands.…”
