Compact Tri-Band Planar Monopole Antenna With Acs-Fed Structure

Abstract

Abstract-In this paper, a compact asymmetric coplanar strip (ACS)-fed printed monopole antenna for tri-band WLAN/WiMAX applications is presented. The proposed antenna is composed of a simple monopole with the high resonant mode at 5.8GHz, an open-ended slot embedded on the ground plane with the low resonant mode at 2.4 GHz, and a meander trip shorted to the ground with the middle resonant mode at 3.5 GHz. The three resonance frequencies of the antenna can be controlled by adjusting the geometries and the sizes of the monopole, the slot and the strip. The antenna occupies a very compact size of 22 × 12 mm 2 including the ground plane, has nearly omnidirectional radiation characteristics and reasonable gain in the operating bands. The simple feeding structure, compactness and uniplanar design make it easy to be integrated within the portable device for wireless communication.

A novel CB ACS-fed dual band antenna with truncated ground plane for 2.4/5GHz WLAN application

“…Le Kang et.al [23] proposed a compact ACS fed antenna with rectangular SRRs for tri-band operation, which employs complimentary split rings on the main radiator to achieve triple band operation. Chen et.al [24] presented a compact tri-Band planar monopole antenna with ACS-Fed structure employs a meandered slot on lateral ground plane to achieve the multiband resonance.…”

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].…”

A Compact Acs-Fed Mirrored L-Shaped Monopole Antenna With SRR Loaded for Multiband Operation

“…Various ACS-fed antenna techniques have been proposed to achieve the multiband characteristics [8][9][10][11][12][13][14][15][16]. Multiband performances were achieved by etching various shaped slots in the radiating element or ground plane of the antenna design in [8][9][10][11], by adding various shaped strips with the radiating element [12][13][14][15] and using loaded capacitance termination technique for dual-band performance in [16].…”

“…In [21], SRR was etched on the radiating element of an ACS-fed antenna for achieving WLAN/Worldwide Interoperability for Microwave Access (WiMAX) applications, but it does not cover the International Telecommunication Union (ITU) band. In [8][9][10][11][12][13][14][15][16] and [20,21], ACS-fed antenna designs cover either WLAN or WLAN/WiMAX or WLAN/ITU band. To cover the WLAN/WiMAX/ITU applications simultaneously, an additional antenna is required which increases the size of the overall system with additional cost.…”
