[email protected] Abstract The channel characterization of handset MIMO antennas in a browsing position has been studied in a propagation environment with a narrow angular power spectrum (APS), such as a street Microcell. We have attempted to make an analytical approach to clarify how a MIMO antenna oriented in a browsing position functions in a street Microcell environment, with re...

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...

This article presents an extremely low-profile tunable antenna design for smartphones with height of only 0.75 mm. The proposed is integrated into the back cover device to utilize existing gap between battery and as efficiently possible. By utilizing both components adjustable feeding weights, designed multiport system covers 3300–4200 MHz frequency range 100 instantaneous bands. In addition ju...

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...

In this letter, a compact planar ultra-wideband mobile antenna with L-shaped extended ground stubs is presented. The proposed handset antenna consists of two planar meandered monopole radiating elements, i.e., main antenna and auxiliary antenna respectively, located at the diagonal corners of mobile phone printed circuit broad with standard size of 136 × 68mm2. Each radiating element is compose...

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...

A novel monopole internal antenna for mobile handsets is presented. The antenna, called the MB antenna, is a modified monopole whose radiating element is implemented in parallel proximity of a ground plane hence allowing for use as an internal antenna in handset applications. Simulation studies indicate that the proposed MB antenna has superior performance over PIFA antennas commonly used in mo...

In this paper, a balanced antenna for mobile handset applications with enhanced bandwidth performance, that covers four bands (GSM1800, GSM1900, UMTS and 2.4-GHz WLAN), is investigated. The antenna is a slot planar dipole with folded structure and a dual-arm on each monopole. A wide bandwidth planar balun is employed to feed the wideband balanced antenna from an unbalanced source. A prototype o...

A low profile planar inverted-F antenna (PIFA) is proposed for mobile handset applications. The proposed antenna covers DCS-1800 & PCS-1900 bands. The antenna consists of a square planar element suspended above the FR4 dielectric substrate. The ground plane is on the bottom side of the substrate. Overall size of the antenna is 22*22*5.2 mm3 and is well suited for mobile handsets due to its low ...
