A Compact ACS‐FED Dual‐Band Meandered Monopole Antenna for Wlan and WiMax Applications

Abstract

In this article, we present the design of a dual-band (3.5 and 5.8 GHz), meandered monopole antenna for Wireless Local Area Network (WLAN)/Worldwide Interoperability for Microwave Access (WiMAX) applications, which is fed by an asymmetric coplanar strip (ACS). The proposed antenna is comprised of an asymmetric ground plane, an ACS-fed structure, and coupled meandered monopole-type of radiating elements that are designed to provide the two desired operation bands, namely 3.5 and 5.8 GHz. The two resonance frequencies of the antenna can be controlled by adjusting the dimensions of the radiating elements, namely the two meandered monopoles, and the gap between them which controls the coupling. The designed antenna has a small size, which is only 20 3 12 mm 2 including the ground plane. Simulated and measured results are presented to demonstrate that the proposed dual-band antenna is well suited for WLAN and WiMAX applications.

A Novel Dual Ultrawideband CPW‐Fed Printed Antenna for Internet of Things (IoT) Applications

“…Various CPW-fed antennas have been reported in literature such as multiband [3][4][5][6][7][8], CPW antennas with added strip for WLAN [9][10][11], and asymmetric coplanar strip antennas [12][13][14][15][16][17][18][19][20]. However, majority of these designs have large antenna dimensions and do not cover all the major bands of WLAN/WiMAX/LTE [13][14][15][16]18].…”

“…However, majority of these designs have large antenna dimensions and do not cover all the major bands of WLAN/WiMAX/LTE [13][14][15][16]18]. Dual-band antenna in [21] with an average gain of 2.5 dB having dimensions 25 mm × 25 mm being compact in size operates only in WLAN band.…”

Design of a Compact Acs-Fed Dual Band Antenna for Bluetooth/Wlan and Wimax Applications

“…It is found that the proposed ACS-fed dual-band antenna is compact in size and it is covering all 2.4/5.2/5.8 GHz WLAN and 3.5/5.5 GHz WiMAX frequency bands with acceptable peak gain of 2.8 dBi. Recently some other structures of compact ACS-fed antennas have been reported in [24][25][26][27]. In [24,25] a dualband acs-fed antenna is proposed for 2.4/5.8 GHz WLAN applications by using the concept of loaded capacitance terminations.…”

“…To decrease the overall size of the antenna, some designs have been reported in [19][20][21][22][23][24][25][26][27] by using the concept of asymmetric coplanar strip (ACS)-fed. In comparison to general coplanar waveguide (CPW)-fed antenna, an ACS-fed antenna structure will consume only 50% area by considering only half of the ground plane of CPW-fed structure.…”

“…Though the antenna is compact in size but it is having the drawbacks of complex structure, narrow bandwidth and limited/no access of 5.2 GHz WLAN and 3.5/5.5 GHz WiMAX band services. In [26,27] two different asymmetric antennas are proposed for dual frequency of operation. Both the reported antennas have compact size but again these structures are having limitations of narrow bandwidth and limited frequency of operation of WLAN/WiMAX bands.…”
