“…From the figure, we can conclude that the proposed antenna features fairly good omnidirectional H-plane patterns and bidirectional E-plane patterns over the desired operating bands. Radiation characteristics have obvious advantages over other similar multiband antennas; for example, in [8,14], there are some sidelobes (especially at relatively high frequency band) in the radiation patterns which degrade the antenna radiation performance. The above radiation characteristics show that the proposed antenna is much preferable for the quad-band applications in the terminal design of integrated wireless communication systems.…”

In order to incorporate different communication standards into a single device, a compact quad-band slot antenna is proposed in this paper. The proposed antenna is composed of a dielectric substrate, T-shaped microstrip patch with a circle slot and an inverted L-slot, and a comb-shaped ground on the back of the substrate. By adopting these structures, it can produce four different bands, while maintaining a small size and a simple structure. Furthermore, a prototype of the quad-band antenna is designed and fabricated. The simulated and measured results show that the proposed antenna can operate over the 1.79–2.63 GHz, 3.46–3.97 GHz, 4.92–5.85 GHz, and 7.87–8.40 GHz, which can cover entire PCS (Personal Communications Service, 1.85–1.99 GHz), UMTS (Universal Mobile Telecommunications System, 1.92–2.17 GHz), WCDMA (wideband code-division multiple access, 2.1 GHz), Bluetooth (2.4–2.48 GHz), WiBro (Wireless Broad band access service, 2.3–3.39 GHz), WLAN (Wireless Local Area Networks, 2.4/5.2/5.8 GHz), WiMAX (Worldwide Interoperability for Microwave Access, 2.5/3.5/5.5 GHz), and X-band SATcom applications (7.9~8.4 GHz). The proposed antenna is particularly attractive for mobile devices integrating multiple communication systems.

“…To generate band for 2.4 GHz WLAN operation, a compact U-shaped antenna is designed whose top and bottom length and width of the patch antenna (29.50 ×38.00×1.6 mm 3 ) and length and width of the ground of the antenna is (39.50 × 48.00 × 1.6 mm 3 ). Patch antennas and planar antennas are proposed for cellular and WLAN applications [2]. The antenna dielectric subtracts FR4 epoxy of thickness of 1.6 mm and dielectric constant of 4.4 is used because it is cheap and easily available.…”

Abstract:In this research paper, microstrip patch antenna with U-shape notched is analysed. Proposed antenna is suitable for band (1.965 -2.508 GHz) for frequency band. The proposed antenna meet the required impedance bandwidth is 24.279 %. The dimension of proposed antenna is (29.5 × 38.0 × 1.6 mm 3 ). This antenna exhibits bandwidth at 2.367 GHz and Gain is 4.01543 dBi. The archived band can be optimized by change parameter of U Shape notched microstrip patch antenna. The variation in the design structure from U shaped antenna is notching in the structure and varying the width of slot. The proposed antenna by introduces notching in the rectangular U shaped radiating patch, is suitable for Wireless application which works around frequency 2.4 GHz and its VSWR is around 1.237.

“…And unlike the single-band 2.45-GHz chip antenna described in [11], or the ultrawideband chip antenna described in [12], the presented chip antenna offers multiband operation in a small package. A compact WCDMA/WLAN antenna with a footprint of 20mm by 22mm [13] and a compact WCDMA/UWB/WLAN antenna with a footprint of 25mm by 25mm [14] were designed previously. The presented chip antenna has even a smaller footprint of 18mm by 17mm.…”

In this paper, a planar antenna operating at 2.45-GHz WLAN band, and a chip antenna operating at 2.45/5-GHz WLAN bands are presented. The chip antenna is evolved from the 2.45-GHz planar WLAN antenna. The chip antenna is, in fact, a planar shorted and folded dipole sandwiched by two FR4 layers above the circuit board. Dielectric layers above and below the radiating element form the chip-like package. The chip antenna has a small footprint of 18mm by 17mm. It has one RF signal lead and two RF ground leads for easy placement and soldering on the circuit board. 3D electromagnetic simulations have been used extensively for the design. The chip antenna exhibits good impedance and gain behavior.
