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.

“…On the other hand, in many cases of practical interest (cellular/PCS, WLAN, GSM/DCS and other dual-band applications [6][7][8][9]) impedance matching over two separate bands can be required. So, in the last years various design methods for dual-band impedance transformers have been proposed [10][11][12][13][14].…”

Abstract-We propose an exact synthesis method which allows the design of dual-band transformers with an arbitrary even number of uniform sections giving equi-ripple impedance matching in two separate bands centered at two arbitrary frequencies. This method is a generalization of the exact Collin-Riblet synthesis of Chebyshev single-band transformers. As compared to a single-band Collin-Riblet transformer encompassing both required passbands, the proposed design yields significantly better performance in terms of passband tolerance and width.

“…Many efforts have been made to develop more versatile dual-band components such as antennas [1][2][3][4], filters [5][6][7][8], coupler [9,10] and transformers [11,12]. Meanwhile, the power divider as one of the most important passive circuits has been widely used in microwave and communication systems.…”

Abstract-This paper presents an approach to the design of a novel dual-band power divider with variable power dividing ratio. To achieve dual-band operation, a novel dual-band quarter-wave length transformer based on coupled-lines is proposed, which is used to replace the quarter-wave length transformer in Wilkinson power divider. The proposed dual-band power divider features a simple compact planar structure with wide bandwidth performance for small frequency ratio. Closed-form design equations with one degree of design freedom are derived using even-and odd-mode analysis and transmission line theory. For verification purpose, power dividers operating at 2.4/3.8 GHz with dividing ratios of 2 : 1 and 1 : 1 are designed, simulated and measured. The simulated and measured results are in good agreement.
