Printed dual ring loop antenna for wide‐dual‐frequency band of wireless applications

Abstract

In this article, a wide and dual band printed dual ring antenna is presented for a wide local area network (WLAN)(2.4/5.4/5.8) applications.The proposed antenna consists of a dual ring loop, which is misaligned array. A printed dual ring loops antenna is fed by a coplanar waveguide. This provides wideband performance and relatively good matching. As result the antenna is operated frequency bands of 1.98–3.55 GHz, 3.82–6.0 GHz, criterion of less than 10 dB. The operating frequency bands of proposed antenna are able to support WLAN communications. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:1317–1318, 2012

Modified three‐circular‐ring monopole antenna for WiMAX/WLAN triple‐band operations

“…Among these antennas, printed monopole antennas play an important role due to their attractive features of a simple structure, a low profile, and a reasonably good performance. Especially, studies on the circular‐ring monopole antenna have been conducted . The circular ring, printed monopole antenna , and M shape surrounded by a ring monopole for wideband operations have been suggested.…”

“…The circular ring, printed monopole antenna , and M shape surrounded by a ring monopole for wideband operations have been suggested. Also, the band‐notched circular‐ring monopole antenna , the CPW dual‐ring loop antenna for dual‐band operation , and the ring monopole UWB antenna with a band notch have been proposed. Conversely, the ring monopole antenna with double‐coupled C‐shaped strips and a dual‐band ring‐shaped antenna for WiMAX/WLAN application have been studied.…”

A Circular-Ring Monopole Antenna with a Half-Circular Ring and Ground Slot for WLAN/WiMAX Triple-Band Operations

“…Among printed monopole antennas, the circular-ring monopole antenna [5][6][7][13][14][15][16][17][18][19][20][21], the ring monopole antenna with double-coupled C-shaped strips [5], the dual-band ringshaped antenna [6], and the ring monopole antenna with a defected ground plane [7] for WiMAX/WLAN application have been studied. In particular, the double-coupled C-shaped strips [5] antenna is designed and fabricated at a substrate with a relative permittivity of 2.65.…”

“…This proposed antenna is made of expensive materials, unlike the conventional FR4 materials. The circular-ring, printed monopole antenna [13], the M-shaped antenna surrounded by a ring monopole [14] for wideband operations, the band-notched circular-ring monopole antenna [15][16][17], the CPW dual-ring loop antenna for dual-band operation [18], the ring monopole UWB antenna with a band notch [19] and the compact-ring monopole antenna for Wi-BAN [20], and the CPW-fed circular-ring monopole with an inverted T-strip line for dual-band operation [21] have already been proposed. In this study, a novel microstrip-fed monopole antenna for WLAN and WiMAX band applications was designed.…”
