Design of a Novel Microstrip-Fed Dual-Band Slot Antenna for Wlan Applications

Abstract

Abstract-In this paper, a novel dual-band rectangular slot antenna for wireless local area network (WLAN) applications in IEEE 802.11b/g/a systems is presented. The proposed antenna, fed by a 50 Ω microstrip line, has size of 32 mm × 28 mm × 1.6 mm. By introducing a pair of U-shaped strips, the proposed antenna can generate two separate impedance bandwidths. The prototype of the proposed antenna has been successfully constructed and tested. The low-band resonant frequency is located at about 2.4 GHz, with −10 dB impedance bandwidth from about 2.3 to 2.5 GHz. The highband resonant frequency is located at about 5.7 GHz, with −10 dB impedance bandwidth from about 4.9 to 6.0 GHz. In addition, the measured results show good radiation characteristics at the two operating bands, proving the dual-band operation of the proposed antenna.

Analysis and Design of a New Dual Band Microstrip Patch Antenna Based on Slot Matching Y-Shaped

“…Future requirements for advanced radar antennas include the need for dual-band operation (Allen et al 2005;Christina et al 2009;Zhilong et al 2012;Qu et al 2006;Andan et al 2009;Khunead et al 2007;Khaled and Saad 2008;Abdelaziz 2006;Gai et al 2010;Saidatul et al 2009;Anden et al 2010;Balanis 1997AND Ghnimi et al 2013. It is essential to integrate multiple bands for use in one device.…”

“…Several approaches are developed in order to design multi-band micro-strip patch antennas such as slot matching concept (Khaled and Saad 2008), as two different radiating elements connected together through a matched section in Abdelaziz 2006), as a pair of U-shaped strips in (Gai et al 2010), as a Fractal planar inverted F antenna in (Saidatul et al 2009).…”

A Novel Rectangular Slot Antenna With Embedded Self-Similar T-Shaped Strips for Wlan Applications

“…Slot antennas have advantages of small size and wide operating bandwidth. Therefore, many different sorts of slot antennas have been proposed, such as M-slot folded patch antenna [4], square slot antenna [5], square slot antenna with embedded crossed strips [6], triangular slot antenna with inset F-shaped strips [7], T-shaped slot antenna [8], E-shaped slot antenna [9], two ring slots antenna [10], rectangular slot antenna with U-shaped strips [11], square ring antenna with tuning stub [12], rectangular slot antenna with fork-like tuning stub [13], triangular slot antenna with fork-like tuningstub [14], etc. Among the antenna designs mentioned above, the antenna in [4] can only excite one resonant frequency band, which cannot cover 2.4-2.484 GHz lower operating band.…”

Dual Rectangular Ring With Open-Ended CPW-Fed Monopole Antenna for Wimax/Wlan Applications

“…For short-and long-range applications, many antenna designs which are suitable for WLAN (2.4-2.484, 5.15-5.35, and 5.725-5.85 GHz) and WiMAX (2.5-2.69, 3.3-3.8, and 5.25-5.85 GHz) operations have been studied [1][2][3][4][5][6][7][8][9][10][11][12]. To adapt to the complicated and diverse WLAN and WiMAX environments, the antennas in these devices should provide stable operations frequency bands.…”
