“…Recently, slot antennas played an important role in wireless technology, because the slot antennas had the advantages of low cost, light weight, easy realization, less conductor loss, and better isolation between the radiating element and feeding network. In the past, the designs of related dual‐, multi, and wideband wide‐slot antennas had been presented using the structures of stripline [1], pattern‐frequency‐dependent [2], asymmetrical CPW grounds [3], elliptical slot [4], Koch fractal slot [5], T‐shaped slot [6], and triangular slot [7]. Owing to the designed broadband (2–6 GHz) wide‐slot antenna, there exist some narrow bands used by WiMAX system operating in the 2.15–2.69/3.4–4.2/4.9–5.85 GHz bands and WLAN in the 2.4–2.484/5.15–5.825 GHz bands.…”

A simple and a compact dual‐band‐notched CPW‐fed wide‐slot antenna, which has a small size of 20 × 25 mm2 is presented for simultaneously satisfying wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. By introducing the dual‐band‐notched mechanism to the wide‐slot antenna, the required impedance bandwidth is achieved over the frequency range from 2.15 to 6.5 GHz (S11 < −10 dB) with dual‐band‐notched bands from 2.69 to 3.4 GHz and from 4.32 to 4.98 GHz, covering all the 2.4/5.2/5.8‐GHz WLAN bands and 2.5/3.5/5.5‐GHz WiMAX bands. The dual reverse split rectangular slits are employed effectively for notching unwanted frequency bands, since it can be implemented with a small dimension and in a high Q operation similarly to the conventional strip‐type dual reverse split ring resonator (SRR). Based on the simulated and measured results, a dual‐band‐notched WLAN/WiMAX wide‐slot antenna using dual reverse split rectangular slits is very effective in rejecting unwanted frequency in terms of its selectivity. This proposed antenna with dual‐band‐notched, broadband matched impedance, stable radiation patterns, good antenna gains and compact size can be suitable for communication products of WLAN/WiMAX applications. © 2011 Wiley Periodicals, Inc.

“…The rapid increase in demand for telecommunications capabilities in recent years has produced a rapid growth in the number of mobile systems, such as DCS, IMT-2000, SDAR, WLANs, LTE and Hiper-LAN with the operating bands of these technologies distributed at 1.8 GHz, 2.1 GHz, 2.4 GHz, 2.6 GHz, 5.2 GHz and 5.8 GHz, respectively. The CPW-fed circular or rectangular slot antenna with circular polarization has been widely used in practical designs [1][2][3][4][5][6][7][8][9][10][11][12][13]. Various techniques for improving the circular polarization bandwidth have been proposed, such as by embedding an arc slot beside the spiral slots, varying the turn number of the spiral slots, and changing the separation between the arc slot and the spiral slots [14].…”

A design procedure for a dual-band CPW-fed linearly and circularly polarized (CP) antenna based on the L-shaped slot antenna is presented in this paper. The slot antenna and the feeding structure are fabricated on the same plane of the substrate so that circuit processes and position alignment can be simplified. By shortening the length of one arm of the L-slot, an additional mode with two orthogonal electrical fields with a phase difference of 90 degree is excited, so that the circularly polarized wave can also be excited. The enhancement of the resonant bandwidth is achieved by utilizing a stub-protruded feedline, adding one finger slit at the other arm slot, and tuning the dimension of the ground plane. A bandwidth of 22.0% (2.23-2.78 GHz) is achieved with an axial ratio < 3 dB for the optimized case.

“…In order to satisfy the IEEE 802.11 WLAN standards in the 2.4/5.2/5.8 GHz operating bands and the WiMAX standards in the 2.5/3.5/5.5 GHz bands, multiband antennas with large impedance bandwidth and excellent radiation characteristic are required. For this, many promising dualor multiband antennas for WLAN/WiMAX applications such as the meander antennas [1][2][3], the slot antennas [4][5][6], the ring patch antennas [7,8], and the planar inverted-F antennas (PIFAs) [9][10][11] have been studied. However, most of them are either complex in physical structure or large in overall size for practical applications.…”

Abstract-A novel trapezoidal slot patch antenna with an embedded trapezoidal strip is proposed for satisfying wireless local area network (WLAN) and worldwide interpretability for microwave access (WiMAX) applications simultaneously. The proposed antenna consists of a rectangular radiation patch with an etched trapezoidal slot and an embedded trapezoidal strip on the top and a beveled ground on the bottom side. By carefully selecting the width of the radiation patch and length of the beveled ground, the proposed antenna can generate two separate bands. The measured results show that the 10 dB return loss bandwidths of the proposed antenna are 430 MHz (2.30-2.73 GHz) and 3460 MHz (3.21-6.67 GHz), which can cover both the WLAN bands (2.4-2.484 GHz, GHz) and the WiMAX bands (2.4-2.6 GHz, 3.4-3.6 GHz, and 5.25-5.85 GHz). Furthermore, good omnidirectional radiation patterns with appreciable gain are obtained over the operating bands.
