“…The performance of this prototype was characterized in terms of the reflection coefficient, gain, and radiation pattern, which were measured in an anechoic chamber. The compact antennae [2][3][4][5][6] of multiband WLAN services occupy a lot of space and are not easy to integrate with other circuitry. The proposed antenna is smaller than Chiu's antenna [2] and Kim's antenna [3] by 56% and 12%, respectively.…”

“…Furthermore, because the rapid spread of smartphones has generated increasing demand for seamless Internet service, WLANs have become a common feature of mobile handsets [1]. While this has led to research into WLAN antennas [2][3][4][5][6], most of the resulting antennas are large or have complicated structural geometries that make them impractical for use in mobile phones.…”

“…Its performance was evaluated by measuring the actual characteristics of a physical prototype. This antenna could be used for triple-band WLAN operations and is much smaller than previous antennas [2][3][4][5][6]. The proposed impedance-matching technique is easily integrated into a PCB without increasing the antenna volume.…”

This paper presents a low-profile multiband antenna suitable for wireless local area networks (WLANs), using a chip inductor and tuning stub for broadband impedance matching. The proposed antenna is compact12×10×1 mm3and covers three bands: 2.4-GHz (2.400–2.484 GHz), 5.2-GHz (5.150–5.350 GHz), and 5.8-GHz (5.725–5.825 GHz). The measured 10-dB bandwidths are 12.0% (2.28–2.57 GHz) in the lower band for 2.4-GHz WLANs and 39.1% (4.81–7.15 GHz) in the upper band for 5 GHz-WLANs. The measured peak gain of the antenna is between 2.7 and 4.39 dBi and the radiation patterns are omnidirectional.

“…To suppress the electromagnetic crosstalk and environmental noise effectively, balanced structure is applied to the design of various components, in particular the balanced filter, balanced FPD, balanced amplifiers, and balanced driven antennas . But to the balanced components, both the input and output ports are designed with fully differential form, which makes them impossible to connect with a single‐ended circuit directly.…”

This article proposes a new dual-band single-ended-to-balanced (SETB) filtering power divider (FPD), which shows the excellent characteristics of wideband common-mode (CM) suppression and good selectivity. By employing the structure of double-sided parallel-strip line with a mid-inserted conductor and a T-shaped defected ground structure etched in the mid-inserted conductor, out-of-phase behavior and high CM suppression can be achieved successfully.Besides, to realize dual-wideband filtering performance and high selectivity, two pairs of step impedance stubs (SIS) loaded quarter-wavelength central line-terminal-shorted three parallel-coupled microstrip lines structure are adopted. Meanwhile, two pairs of resistors are introduced so as to realize excellent isolation. To verify effectiveness of the design method, a prototype of dualband SETB FPD which operates at 3.2 and 4.9 GHz is designed, fabricated, and tested. Final results exhibit that the new dual-band SETB FPD possess high selective dual-band differential mode response, wideband CM suppression, and excellent isolation between the balanced output ports.

“…The multiband antenna must have simple structure, small size, light weight, low cost, and be easily integrated with RF circuits. So far, numerous antennas have been proposed to reduce size, enhance bandwidth for WLAN application . The dipole triple‐band antenna of size 15 × 70 mm 2 comprises three pairs of dipoles placed back to back to get the WLAN bands .…”

In this article, a compact multiband monopole antenna is proposed to cover the frequency band for wireless local area network and worldwide interoperability for microwave access application. The multiband monopole antenna has the advantage of compact size of 15 × 30 mm2. The proposed antenna is an S‐shaped strip connected with a notched rectangle loop radiation patch with a ground plane, and there is a slot in the ground plane. The two lower bands are achieved by the rectangle loop patch and the higher band is achieved by the slot in the ground plane. The impedance bandwidth for 10 dB return loss at 2.46, 3.8, and 5.4 GHz, are from 2.4 to 2.51 GHz, 3.20 to 4.07 GHz, and 5.08 to 5.85 GHz, respectively. Experimental results show that the antenna gives omnidirectional radiation patterns and stable antenna gains in the operating bands with the compact size. © 2014 Wiley Periodicals, Inc.
