Abstract-In this paper, a novel double-band integrated antenna for applications in WLAN is presented and studied. Based on the mature dipole theory, radiation elements are printed on the two faces of a low cost FR4 substrate. The two dipoles are designed on the sides of the feedline, which can reduce the impact of each other availably. The distance between the two arms and the width of the arms plays an important role in improving the impedance matching. Furthermore, by folding the arms efficiently, the current distribution of the proposed antenna is extended, and the dimensions of the proposed antenna can be reduced. The size of the designed antenna is just 34 mm × 24 mm × 1 mm (about 0.27λ × 0.19λ × 0.008λ, λ is the wavelength relative to the frequency 2.4 GHz). Moreover, the prototype of the antenna is constructed and tested, which shows a good agreement with simulated result. The measured bandwidths, ranging from 2.35 GHz to 2.61 GHz and from 4.7 GHz to 6.0 GHz respectively, are obtained with return loss less than −9.54 dB (about 2 : 1 VSWR). The proposed antenna covers 2.4/5 GHz WLAN bands, and radiation patterns with good omni-directional radiation in the operating frequency are observed.

“…Some researchers and scholars have done lots of work on multiple band antenna research, various types of printed antennas have been reported [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. The planar monopole antenna is often adapted to realize multiple-band operation, with various structures such as letter-like shape [1][2][3][4][5][6]12], plant-like shape [7], and fractal structures [8][9][10][11][15][16][17].…”

Abstract-The method of a T-shaped antenna loading T-shaped slots for multiple band operation is presented in this paper. Inspired by the fractal antenna, the proposed method is intended to be used for designing multiple band antennas. Through loading T-shaped slots in the terminals of a Tshaped antenna, dual or triple operating bands can be achieved. In order to validate the feasibility of this method, this type of antenna is designed and simulated. The antennas are respectively fed by two different feeding transmission lines (microstrip transmission line and coplanar waveguide (CPW) transmission line) for the purpose of identifying the method that can be commonly used. The parametric analysis in detail has been given to explain the effects of the key parameter variations. For WLAN and WiMAX applications, the antennas are fabricated and measured. Both simulated and measured results are presented to demonstrate the feasibility of these designs.

“…The lower band ranges from 2.4 to 2.484 GHz for IEEE 802.11b/g and upper band covers frequency band from 5.15-5.35/5.725-5.825 GHz for IEEE 802.11a. Nowadays, dual-band WLAN systems combining IEEE 802.11a/b/g standards are becoming more attractive [1,2]. A dual-band antenna is a key component for such communication systems [3][4][5][6][7][8][9], especially for "universal" applications, where it should be covering the whole 2.4-2.484 GHz and 5.15-5.825 GHz bands for dual-band WLAN.…”

Abstract-This paper presents a novel monopole antenna which uses split ring loading in order to achieve a dual-wideband operation for WLAN (2.4/5.2/5.8 GHz) application. By adjusting the split ring position and its natural resonant frequency, the proposed antenna can produce more than 1 GHz wideband match in the 5 GHz band. According to the measured results, the bandwidth with reflection coefficient less than −10 dB is about 715 and 1017 MHz in the two bands. Good radiation patterns are also achieved. The dimensions of the monopole loaded with split ring are 27.2 mm × 16.2 mm × 1 mm, which is suitable for a hallway antenna or ceiling mount antenna of WLAN application.
