Multiband Handset Antenna With a Parallel Excitation of PIFA and Slot Radiators

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...

Novel Miniaturized Multiband and Wideband PIFA Antenna for Wireless Applications

Design of multiband antennas with low volume is of practical interest for the ever growing wireless communication industry. In this paper, the design of PIFA antenna with multiband resonance for WiMAX, WLAN, HIPERLAN/2 applications by using genetic algorithm (GA) is presented. Genetic algorithm (GA) method was used to design the shape of the patch and the shape of the ground plane simultaneousl...

A multiband double square slot antenna with fractal geometry

A multiband double square loop antenna with fractal concept is proposed. The design is based on an initial model of fractal geometry and a double square slot antenna structure. The initial model of fractal geometry influences to the second frequency band and it will be carefully investigated. The radiation patterns of the proposed antenna are still similarly to bidirectional radiation pattern. ...

Multiband Slot Loaded Uniplanar CPW-fed Monopole Antenna with Asymmetrical Arms

This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN range while the placement of the inverted U-shaped strip provides a better impedance matching for the lowest resonant ...
