TL;DR: In this paper, a multiband planar inverted F antenna for mobile handset applications is presented, where the idea of meandering technique is introduced into the conventional rectangular patch antenna for higher GSM frequency.
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 printed meander line antenna with a shaped ground plane and a back coupled rectangular patch is proposed for wireless local-area network (WLAN) applications in the 2.4-2.35 GHz frequency range.
Abstract: A printed meander line antenna is described with a shaped ground plane and a back coupled rectangular patch. The prototype is proposed for wireless local-area network (WLAN) applications in the 2.4-2.48GHz and 5.15-5.35 GHz frequency range. Dual-band operation, resonance impedance matching, and wide impedance bandwidth are the characteristics of the antenna. The antenna impedance matching for the first-resonance is provided by applying a shaped ground plane. The second even-mode resonance is generated by adding a rectangular patch at the back of the meander antenna. The impedance bandwidth for a return-loss less than -10 dB is 11% and 6% for the first- and the second-resonance, respectively. Furthermore, the second-resonance frequency can be tuned by the length of the rectangular patch and it meets the requirements for the IEEE 802.11a WLAN (5.15-5.35 GHz and 5.470-5.725 GHz or 5.725-5.825GHz). In fact, the second-resonance frequency can be continuously adjusted between 5.2 and 7 GHz with a little effect on the first-resonance

TL;DR: In this paper, a planar inverted-F antenna is proposed for mobile communication applications, and the S11 parameters are measured and bandwidths of 3.4, 10.3, and 2.1% are obtained for the corresponding band, respectively.
Abstract: A novel compact triple-band (GSM, DCS, and ISM) planar inverted-F antenna is presented. A prototype was constructed and studied. The S11 parameters are measured and bandwidths of 3.4%, 10.3%, and 2.1% are obtained for the corresponding band, respectively. For practical application, the presence of the plastic case and the hand were considered, and the resulting data of their influence were obtained and discussed. The radiation patterns and gains are also measured. All the results show that this type of PIFA is suitable for mobile-communication applications. © 2004 Wiley Periodicals, Inc.

TL;DR: A new design of a dual band Planner Inverted-F Antenna, for cellular telephone systems and other applications is presented, and the designed antenna has been simulated using the CST 2010 software.
Abstract: In this paper, a new design of a dual band Planner Inverted-F Antenna (PIFA), for cellular telephone systems and other applications is presented. The PIFA antenna is composed of ground plane, patch antenna, feeding post and shorting plate connected to the ground plane. The designed antenna has been simulated using the CST 2010 software. The simulated results for the resonant frequency, return loss, radiation pattern and gain are presented and discussed. The bandwidths of 114MHz and 176MHz for GSM900 and GSM1900 respectively are achieved on the basis of ≤ −6 dB return loss as an acceptable reference in mobile phones applications. A gain of 1.933dB and 4.74dB is obtained in lower and higher frequency respectively.

TL;DR: In this article, a dual-band folded planar antenna for WLAN/Bluetooth applications is introduced, formed by modifying the geometry of a rectangular patch antenna to include a shorting wall, folded patch feed and a slot.
Abstract: A novel small dual-band folded planar antenna for WLAN/Bluetooth applications is introduced, formed by modifying the geometry of a rectangular patch antenna to include a shorting wall, folded patch feed and a slot. The size of the antenna is successfully reduced to a volume of 15 × 12 × 7 mm 3 . The impedance bandwidth achieved were 3.29% and 28.4% (equivalent to return loss # -10 dB) for lower and higher frequency respectively; these covers the IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and IEEE 802.11n (MIMO) bands for wireless communication and future 4G wireless operation of mobile VoIP/Vo WLAN handset phone. Details of the proposed antenna characteristics, including impedance bandwidth, VSWR, gain and far field radiation patterns are presented and discussed. The tuning effects of the geometry parameters on impedance matching of the proposed antenna are also investigated.
