Compact Mobile Quad-Band Slot Antenna Design for GPS L1, WiMAX, and WLAN Applications

Abstract

In this paper, an asymmetric compact multiband slot antenna is proposed for global positioning system (GPS), worldwide interoperability for microwave access (WiMAX), and wireless area network (WLAN) applications. The top plane, a ground is composed of a rectangular slot with a trapezoidal-like stub, an inverted U-shaped slot at the right side of the rectangular slot, an inverted L-shaped slot at the left side of the rectangular slot, and three stubs. The proposed antenna is fed by an asymmetric cross-parasitic strip on the bottom plane. By properly designing the slots and stubs, four resonant frequency bands are achieved with -10 dB reflection coefficient bandwidths of 50 MHz, 400 MHz, 390 MHz, and 830 MHz in the 1.57 GHz GPS band, 2.4 GHz WLAN band, 3.5 GHz WiMAX band, and 5.5 GHz WLAN bands, respectively. The antenna has a total compact size of 13 mm × 32 mm × 0.8 mm. Simulated and measured results indicate that the proposed antenna has sufficient bandwidth and good radiation performance in each band.Key Words: GPS, Quad-Band, Slot Antenna, WiMAX, WLAN.

“…Many multiband antennas are reported in the literature operating at different frequency bands. [7][8][9][10][11][12][13][14][15] The multiband characteristics were obtained by using patches of various shapes. In Reference 7, a multiband antenna is realized by etching inverted multiple U-shapes.…”

“…Many techniques have been used to achieve multiband operation in printed antennas including the usage of several strips, stacked structures, elongated arm, and creating different current paths . However, these techniques resulted in larger dimensions having larger ground plane thus resulting in structural complexity.…”

“…Many techniques have been used to achieve multiband operation in printed antennas including the usage of several strips, stacked structures, elongated arm, and creating different current paths. [1][2][3][4][5][6][7] However, these techniques resulted in larger dimensions having larger ground plane thus resulting in structural complexity. In addition to these conventional techniques, LC resonator loading has also been used to achieve multiband operation in printed antennas without facing design complexity.…”
