Abstract: This paper presents a multiband planar inverted F antenna for mobile handset applications. The novel idea of meandering technique is introduced into the conventional rectangular patch antenna for higher GSM frequency. The proposed antenna features rectangular patch antenna for GSM (880-960MHz) band and meandering slot for DCS (1710-1880MHz) and GSM (1710-1880MHz) bands. The impedance bandwidth of proposed antenna is 41MHz (0.882GHz-0.923GHz) at lower band and 110MHz (1.66GHz-1.77GHz) at upper operating band. The radiation pattern is nearly omnidirectional in both the planes. The parametric studies were carried out by High Frequency Structure simulator (HFSS).

TL;DR: This chapter will focus on the design of the non-reversible series resonant converter.
Abstract: After the introduction and justification of several more or less well known and complicated conversion topologies based on series resonance, this chapter will focus on the design of the non-reversible series resonant converter. Following this, a brief description will be given concerning a collection of DC/DC and DC/AC converters developed under various industrial contracts by the Laboratoire d’Electrotechnique et d’Electronique Industrielle (L.E.E.L), Toulouse, France.

TL;DR: In this article, a multiband planar antenna design for cellular and wireless communications is presented, which realizes an overall size of 40×40×1.6 mm3 and offers good radiation characteristics and gain for desired frequency bands.
Abstract: A multiband planar antenna design is presented for cellular and wireless communications. The presented antenna realizes an overall size of 40×40×1.6 mm3. It consists of a Gshaped and inverted L-shaped radiator. The G-shaped radiator is responsible to offer 1800 MHz, 2.45 GHz, and 3.5 GHz frequency bands, while the inverted L-shaped radiator can provide resonance at 900 MHz and 5 GHz frequency bands. Moreover, the proposed multiband antenna offers good radiation characteristics and gain for desired frequency bands. The proposed antenna design is also fabricated and measured to validate the simulation results.

TL;DR: In this article, a dual-band planar inverted F antenna suitable for the application as a global system for mobile communication/digital communication system (GSM/DCS) dualband mobile phone internal antenna is proposed and implemented.
Abstract: A compact dual-band planar inverted F antenna suitable for the application as a global system for mobile communication/digital communication system (GSM/DCS) dual-band mobile phone internal antenna is proposed and implemented. The proposed antenna has three resonant elements, two meandered metallic strips of slightly different lengths and one nearly-rectangular patch, which are printed on a supporting FR4 substrate and arranged in a compact configuration. These three resonant elements share a common shorting pin, and for the GSM (890-960 MHz) operation, the proposed antenna is operated with the two meandered strips both resonated as a quarter-wavelength structure, leading to a wide bandwidth formed by two resonant modes. For the upper band of the proposed antenna, three resonant modes are generated, two from the second higher-order modes of the two meandered strips and one from the nearly-rectangular patch, leading to a wide bandwidth covering the DCS band (1710-1880 MHz). The antenna design and experimental results are presented.

TL;DR: In this paper, a planar inverted-F antenna (PIFA) is proposed to operate in the IEEE 802.11b/g, HIPERLAN2 and IEEE 802.,11a/g frequency bands.
Abstract: A novel compact planar inverted-F antenna (PIFA) to be mounted on laptop computers is presented. The proposed multiband single-feed PIFA simultaneously operates in the IEEE 802.11a, IEEE 802.11b/g, and HIPERLAN2 frequency bands. The multiband behavior is obtained by combining a trapezoidal feed plate with two different resonance paths in the radiating structure. The overall size of the antenna renders it suitable to be installed at the border of the display of a notebook. Simulation results are compared with measurements performed on an antenna prototype.

TL;DR: In this paper, a tuning circuit, comprising an RF switch and discrete passive components, has been completely integrated into the antenna element, which is thus free of dc wires, and the proposed tuning method has been demonstrated with a dual-band PIFA capable of operating in four frequency bands.
Abstract: A novel method is presented for electrically tuning the frequency of a planar inverted-F antenna (PIFA). A tuning circuit, comprising an RF switch and discrete passive components, has been completely integrated into the antenna element, which is thus free of dc wires. The proposed tuning method has been demonstrated with a dual-band PIFA capable of operating in four frequency bands. The antenna covers the GSM850, GSM900, GSM1800, PCS1900 and UMTS frequency ranges with over 40% total efficiency. The impact of the tuning circuit on the antenna's efficiency and radiation pattern have been experimentally studied through comparison with the performance of a reference antenna not incorporating the tuning circuit. The proposed frequency tuning concept can be extended to more complex PIFA structures as well as other types of antennas to give enhanced electrical performance.
