“…The overall size of the proposed antenna is larger than that of [19] but has the advantage of CPW-feed. The antenna size in [20] is also smaller than this design, but its lowest frequency of operation is higher. In [21], the lowest operation band is at 800 MHz but the structure is not planar and is designed specifically for smartphones.…”

Abstract-A planar UWB antenna with added GSM 1800/WMTS and UMTS bands is presented. A CPW-fed circular patch is used to obtain wideband characteristic covering the UWB range. A novel slot formed by merging the alternate sides of a hexagon with isosceles triangles is inserted in the patch to obtain dual-band operation with the lower band suitable for GSM 1800 operation. By inserting a bent monopole in the space created by the slot, a triple-band antenna is developed with two lower bands suitable for WMTS and UMTS operation. The antenna prototype is fabricated and tested. Simulated and experimental results are in good agreement. The antenna exhibits stable radiation characteristics and nearly constant group delay in the UWB range.

“…In [10], a CPW structure with three symmetrical U-shaped strips was utilized to achieve triple-band UWB performance. In [11], a compact multi-band antenna covering Bluetooth, WiMAX, WLAN, and ITU standards frequency bands was proposed by adding three stubs to the coplanar waveguide (CPW) structure, but the antenna did not cover the whole UWB range.…”

Abstract-In this research, a compact printed antenna design operating on ultra-wideband (UWB) and three extra wireless communication bands is proposed. An ellipse-shaped monopole is utilized to realize UWB application (3.1-10.6 GHz). The modified ground employs three folded Capacitive Loaded Line Resonators (CLLRs) to obtain triple relatively lower communication bands, including parts of global System for Mobile Communications (GSM) band at the centre frequency of 1.78 GHz, Wideband Code Division Multiple Access (WCDMA) band at the centre frequency of 2.15 GHz, and Wireless Local Area Networks (WLAN) band at the centre frequency of 2.4 GHz.The CLLRs are designed with quarterwavelength to control the corresponding frequencies independently. Good agreement is achieved between the simulation and measurement to verify our presented design. The basic, dual-, triple-band UWB antennas are also simulated and good results are obtained. Small group delay variations across UWB frequencies are obtained for the presented antenna and reference antennas, with some level of distortion observed.

“…For these applications, several promising dual or multiband planar antennas for the WLAN/WiMAX applications have already been proposed in [1][2][3][4][5][6][7][8][9][10][11][12]. In [1][2][3], by employing different shapes of monopole such as T-shaped monopole, double-T monopole or modified inverted-L monopole, the antennas can achieve dual-band operations and are simple in structure, but none of the above designs can achieve a dualband bandwidth so large to cover the whole WLAN/WiMAX bands.…”

“…Unfortunately, although the above designs achieve bandwidth enhancement, most of them have a relatively large overall size and occupy too much of the device space. In addition, several other types of compact antennas with multiband have been found in recent literatures, including a quadband antenna with three L-shaped slots and a rectangular slot [8], a koch fractal printed slot antenna [9], an elliptical slot antenna with "T"-and "L"-shaped slots and three quarter-wavelength stubs [10], a rectangular patch with dual U-shaped slot [11] and a dual rectangular ring with open-end [12]. But they are all complicated in configurations to reduce the antenna's application.…”

Abstract-A novel compact coplanar waveguide (CPW)-fed printed antenna with triple bands for WLAN and WiMAX applications is presented. By using a parasitic circular patch, a pair of symmetrical inverted-L strips and a 50-Ω transformer, the antenna can effectively provide a good input impedance matching. The tuning effects of the ground size, the parasitic circular patch and the symmetrical inverted-L strips to the resonance and matching condition are then examined, and the prototype of the proposed antenna is further fabricated and measured. The experimental and numerical results exhibit that the antenna has impedance bandwidth with 10 dB return loss 2.32-2.80 GHz, 3.06-4.13 GHz and 5.03-6.04 GHz, which can cover both the WLAN 2.4/5.2/5.8 GHz bands and the WiMAX 2.5/3.5/5.5 GHz bands. Also, a stable monopole-like radiation pattern and an average antenna gain of 3.06 dBi across the operating bands have been obtained.
