“…Conventionally, the unbalanced planar inverted F antenna (PIFA) is one of the most popular candidates for compact built-in antenna in mobile handsets. PIFAs use the ground plane as a part of the radiator, enabling very small antennas to achieve adequate gain and bandwidth [1][2][3][4][5]. As the feed is unbalanced, however, radiating currents are induced on both the ground plane and the antenna element in almost every case.…”

A balanced antenna for wireless portable devices applications with multiple band operational performance is investigated and discussed. The designed antenna is weakly ground-couple, although can be considered as an energy-efficient radiator. The antenna structure is a thin-strip planar dipole with a dual-folded structure on each arm. The performance of the proposed antenna is analysed and optimised for WLAN and WiMAX applications over the relevant frequency bands, including the 2.4 and 5.2 GHz WLAN bands and the 2.5 and 3.5 WiMAX bands. For validation, the antenna prototype was fabricated and tested. The performance of this balanced antenna was verified and characterised in terms of the return loss, radiation pattern and power gain. The predicted and measured results show acceptable agreement and the results also confirm good impedance bandwidth characteristics with excellent dual-band operation.

“…A number of WLAN multiband antennas have been proposed in literature [1][2][3][4][5][6][7][8][9][10]. There are great demands to integrate the IEEE 802.11 WLAN standards for the 2.4 GHz (2.4-2.484 GHz), 5.2 GHz (5.15-5.35 GHz), and 5.8 GHz (5.725-5.825 GHz) bands into a single small wireless unit.…”

The design of a compact antenna for use in wireless devices of the 2.4/5.2/5.8‐GHz wireless‐local‐area network (WLAN) is presented. The antenna consists of an L‐shaped monopole radiator (L‐element) with microstrip‐fed on one side of the substrate and a protruding meander‐microstrip ground stub (M‐stub) on the other side. The L‐element and the M‐stub generate a high‐frequency band at around 5.4 GHz for the high WLAN bands and a low‐frequency band at around 2.44 GHz for the low WLAN band, respectively. The antenna has a very compact size of only 25 × 25mm2, including the ground plane. Computer simulation is used to study, design, and optimize the antenna. For verification of the simulated performance, the antenna is fabricated and measured using the antenna measurement system, Satimo Stargate. The effects of the feeding cable used in measurement cause discrepancies between the simulated and measured performances. To verify the cable effects, the feeding cable is modeled in simulation. With the use of the cable model, the simulated and measured performances show very good agreements. A practical application of the proposed antenna is also studied by installing it on a printed‐circuit board having the similar size of a smartphone. The impedance bandwidth, radiation pattern, peak gain, and efficiency of the antenna are studied and presented. Results show that the antenna is a potential candidate for small WLAN wireless devices. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:469–475, 2014

“…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.
