CPW-Fed Compact Multiband Monopole Antenna for Wlan/Wimax/X-Band Application

Abstract

A CPW-fed compact multiband planar printed monopole antenna for WLAN/WiMAX/X-Band applications is presented in this paper. The structure size of antenna is 0.144λ 0 ×0.176λ 0 ×0.008λ 0 . The proposed antenna is composed of three monopole radiators, a microstrip feed line, and the ground with chamfer. With these structures employed, the antenna can generate four different resonances to cover the desired bands while maintaining low profile. The antenna simulation results show four distinct bands from 2.24 to 2.85 GHz, from 3.29 to 4.12 GHz, from 5.13 to 6.24 GHz, and from 6.58 to 8.57 GHz, which cover the entire WLAN bands (2.4-2.484, 5.15-5.35, and 5.725-5.825 GHz), WiMAX bands (2.5-2. 69,, and X-band satellite communication systems . For verification of simulation results, a prototype of quad-band antenna is designed, fabricated, and tested. The simulated and measured return losses, radiation patterns, and gains are presented. The proposed antenna possesses compact size, simple structure, high gain, and omnidirectional radiation pattern, which make it a suitable candidate used in small/portable WLAN/WiMAX/X-Band devices.

Design of Dual-Band Microstrip Patch Antenna for Wireless Local Area Network Applications

“…The microstrip patch antenna is a type of directional antenna, meaning it transmits signals in a specific direction [6]. It can be designed to have omnidirectional or directional characteristics, which is beneficial in WLAN applications as it can provide higher gain in specific directions and overcome obstacles that may block signals [7]. The microstrip antenna functions as a resonant radiator, emitting electromagnetic waves continuously between its top radiation patch edges and the grounding plate, creating a radiation field via the mutual electromagnetic interaction between these two objects.…”

Material Relative Permittivity Determination From the Inhomogeneous Transmission-Line Secondary Parameters

“…Electronic devices are increasingly attractive [1]- [4] due to their potential application in several fundamental communication systems: solar cells [5], vehicle communications, satellites, new precision-guided munitions, etc. Understanding the electronic processes in these materials and devices is of fundamental importance to improve electronic performance and develop new materials for future technologies [6], [7].…”

A compact CPW-fed monopole antenna for multi-band application

“…The multi-band technology of the antenna allows a single antenna to realize multiple working frequency bands in multiple communication standards, which is gaining increasing attention. Researchers have proposed a series of methods, such as gap loading technology [1][2][3][4][5][6][7][8], multi-branch technology [9][10][11][12][13][14][15], reconfigurable technology [16,17], loading a soft magnetic ferrite film [18], and so on.…”

“…A tri-band E-shaped printed antenna with C-shaped slots was presented by Kim Ho Yeap [1], which operated at a tri-band of 1.51/2.46/6.11 GHz. A coplanar waveguide (CPW)-fed compact tri-band antenna composed of three monopole radiators is proposed by Liu in [9]. The antenna works at three bands 2.36-2.82, 3.28-3.88, and 4.50-6.53 GHz for WLAN/ WiMAX application.…”
