A Compact Dual-Band Printed Monopole Antenna for Wimax/Wlan Applications

Abstract

Abstract-A compact printed dual-band antenna for WiMAX/WLAN applications is proposed in this paper. The dual-band monopole antenna consists of a triangular patch and two folding arms shorted to the ground plane. The proposed antenna features a low profile and compact dimension. To avoid via process in the fabrication, the triangular patch and two folding arms are separately constructed on the two sides of a FR4 substrate. By employing this structure, five different resonances can be yielded. The triangular patch provides two resonant modes (4.62 GHz and 7.05 GHz). The two folding arms produces three resonances at 2.43GHz, 3.43 GHz, and 6.59 GHz. A prototype of the dual-band antenna is experimentally fabricated and tested. The measured results shows good impedance bandwidth and radiation pattern.

A Compact Quad-band Monopole Antenna for IoT Application in WSNs/WLAN/LTE Bands

“…Some studies used slot structure to achieve a multi-band resonance with a compact antenna size [1][2][3]. Also, some other promising structures have been proposed, such as monopole [4,5], CPW-fed [6,7], ACS [8, 9] and PIFA [10]. In [2], An instance is shown that a printed planar antenna with a size of 30 × 30mm 2 generated three resonant modes by two dissimilar inverted L-shaped slots and a mushroom-shaped slot loaded into the antenna.…”

“…In [2], An instance is shown that a printed planar antenna with a size of 30 × 30mm 2 generated three resonant modes by two dissimilar inverted L-shaped slots and a mushroom-shaped slot loaded into the antenna. In [4], a compact microstrip-fed dual-band monopole with size of 10 × 30mm 2 was presented to cover WiMAX and WLAN bands by a triangular monopole and two folding arms shorted to the ground plane. In [9], a ACS structure antenna with a size of 28 × 28mm 2 used a folding microstrip line radiator along with unilateral ground plane to generate four desired frequency bands, while the bandwidth of each band is rather limited.…”

“…Recently, the rapid progress of IoT increases the difficulties of multi-band antenna toward compact, low profile and board bandwidth for IoT devices. Therefore, a considerable amount of research and approach has been achieve to cover desirable bands and reduce the size [1][2][3][4][5][6][7][8][9][10]. Some studies used slot structure to achieve a multi-band resonance with a compact antenna size [1][2][3].…”

A Quad-band Compact Diversity Antenna for Mobile Handset Devices

“…In [2], An instance is shown that a printed planar antenna with a size of 30 × 30mm2 generated three resonant modes by two dissimilar inverted L-shaped slots and a mushroom-shaped slot loaded into the antenna. Also, some other promising structures have been proposed, such as monopole [4,5]. In the diversity aspect, some efforts are made to enhance the diversity performance and reduce the volume.…”

“…However, the restrict space limitation in the mobile handset devices design increases the difficulties of multi-band antenna toward compact, low profile and board bandwidth for the devices. Therefore, a deals of research and approach has been achieving to increase bandwidth and reduce the antenna volume [1][2][3][4][5]. Slot structure was used to achieve a multi-band resonance with a small size in some studies [1][2][3].…”
