“…Modern mobile equipments are often required to operate at multiple frequency bands to facilitate the application for various communication needs. Thus, many antennas with broadband and multiband functionality, monopole antennas, planar antennas and slot antennas, have been described in recent years [1][2][3][4][5]. Printed antennas with moderate radiating characteristics can be operated at multiple frequency bands.…”

“…Printed antennas with moderate radiating characteristics can be operated at multiple frequency bands. They support dual-band operation in the wireless local area network (WLAN) communication systems [1][2][3]. However, in other antenna designs, a slot patch and a broad ground plane are required for broadband and multiband systems, including the digital communication system (DCS), the personal communication system (PCS), the universal mobile telecommunication system (UMTS) and the 2.4-and 5-GHz WLAN bands.…”

Abstract-A new design of dual-band antenna for DCS/PCS/UMTS/ WLAN/WiMAX applications is proposed. Using two metamaterials omega-shaped structures, a good impedance matching the dual-band mode is obtained. The proposed prototype antenna is fabricated on a 1.5 mm thick FR4 epoxy substrate with a relative dielectric permittivity ε r = 4.4 and a loss tangent tan σ = 0.02. Good monopolelike radiation patterns and antenna gains over the operating bands have also been observed. Effects of each omega particle on the antenna performance and their coupling are all examined and discussed.

“…Kung et al also proposed a similar model as Rmili's and printed balum on the substrate for coupling feeding, but this antenna does not have high gain [2]. Hwang et al had manufactured a coaxial-fed antenna working in ISM-band and its impedance bandwidth is 400 MHz with reflection coefficient less than −10 dB, and the maximum gain is 1.4 dBi in the band [3]. Liu and Su proposed a square cylindrical monopole antenna fabricated using a cross-shaped metal plate.…”

Abstract-A novel coplannar waveguide (CPW) cross-fed antenna which is wideband, high-gain and omnidirectional is proposed. After simulating the antenna model by CST MICROWAVE STUDIO R , the results show that this antenna not only has compact size, but also can effectively broaden operating band, improve gain and remain omnidirectional. In addition, adjusting antenna elements' dimension and spacing can control the central frequency position of operating band and bandwidth. The simulated results of antenna surface currents can be used to explain the reason of antenna possessing broadband and omnidirectional high-gain characteristics. A CPW cross-fed antenna operating at 2.4 GHz is designed and manufactured for measurement. The prototype is printed on a FR-4 epoxy resin board with 1 mm thickness. The experimental results indicate that the operating band is 2.35-2.85 GHz with reflection coefficient less than −10 dB (relative bandwidth 19.2%), and maximum gain in H-plane can achieve 5.2 dBi. Measured results well match the simulated ones. Moreover, the total antenna size is 187 mm × 22.5 mm (1.5λ × 0.18λ), which can make it suitable in WLAN systems.

Abstract-This paper presents a printed slot antenna using the printed structure in order to improve its dual-band and compact size performances. The printed slot structure is used as additional resonators to produce dual-band operation for covering the worldwide interoperability for microwave access (WiMAX) and the 5.2-GHz wireless local area network (WLAN) bands. In order to achieve wideband and multi-band operation, the slot antennas with a slotted structure and an inverted-L slot structure for covering the wireless communication operations are developed. Finally, we propose a novel and compact printed slot antenna with mixing slot structures to obtain and cover for the 2.4-GHz WLAN (2.4-2.484 GHz), the WiMAX (IEEE 802.16e in the Taiwan: 2.5-2.69/3.5-3.65 GHz), and the 5-GHz WLAN (5. . Several properties of the proposed antennas for dual-and multi-band characterize radiation performances such as impedance bandwidth and radiation pattern. Measured gain has been confirmed experimentally for the multi-band wireless communication systems.
