Multiband Folded Loop Antenna for Smart Phones

This paper presents a multiband folded loop antenna for smart phone applications. The proposed antenna with a symmetric loop pattern generates four resonance modes in the design bands. The current distributions of the excited resonance modes are analyzed to confirm the mode characteristic. Using a pair of tuning elements near the feed port, the impedance bandwidth is broadened to cover GSM850/G...

Wideband Tunable PIFA Antenna with Loaded Slot Structure for Mobile Handset and LTE Applications

A compact planar inverted F antenna (PIFA) with a tunable frequency response is presented. Tuning of the resonant frequency is realized by loading a varactor on an embedded slot of the proposed antenna structure without further optimizing other antenna geometry parameters. The antenna exhibits a wide frequency range from 1570 to 2600 MHz with a good impedance matching (S11 ≤ -10dB) covering the...

Compact Surface-mount Wideband and Multi-band Internal Chip Antenna for Mobile Handset

A novel and broadband spiral chip antenna is presented in this paper. The size of the proposed antenna is 20× 3.2 × 8mm and is suitable to be embedded in a mobile phone as an internal antenna. Also, this antenna is designed to be installed at the newest mobile handset whose size is 40 × 93mm. The minimization of this antenna was realized by using spiral line structure on FR-4 of dielectric perm...

Design of a Wideband Microstrip Antenna for Mobile Handset Applications

This article summarizes the design, construction and experimental results for a new wideband miniaturized antenna operating in the 1.9 GHz band. This antenna is intended for handset applications, and may also be used as an element in a larger array. Using shorting pins at the zero-potential plane, a compact antenna with a 21 percent bandwidth was designed and tested, with quite good agreement b...
