چکیده

A folded loop antenna for handsets has already been introduced and shown as one of balanced feed antennas for handsets, which is very effective to mitigate the antenna performance degradation due to the body effect. In addition, to be lower profile of folded loop antenna, Built-in folded dipole antenna, which has a structure folded loop elements sideway so that the antenna can be placed on the ground plane (GP), has been proposed. In this paper, as an improved impedance matching technique and more wideband antennas, characteristics of a folded dipole antenna and a folded monopole antenna for handsets by using a parasitic element are analyzed.

Self-balanced and Wideband Characteristics of Improved Built-in Folded Dipole Antenna for Handsets

In conventional antennas, such as a monopole antenna and a planar inverted-F antenna (PIFA) for handsets, some gain degradation has been often observed when the operator holds the handsets at a talk position. This is caused by the variation of the current on the conducting box used in the handset due to human body effect. Because of this point, we have to consider reducing the current flow on t...

A Multiband Multiple-input Multiple-output Antenna System for Long Term Evolution and Wireless Local Area Networks Handsets

A novel multiband multiple-input-multiple-output (MIMO) antenna system is proposed. The MIMO antenna system consists of two antenna elements, each of which comprises of three radiators: a driven monopole, an S-shaped strip and an inverted F-shaped strip and occupies footprint of 15x18.5x0.8 mm3 only. The driven monopole acts as a quarter-wave monopole and stimulate higher mode resonance. The tw...

Triple Band MIMO Antenna for WiMAX using Electromagnetic Simulator

Folded monopole antenna (FMA) which can cover 2.5/3.5 GHz bands of WiMAX is already reported. In this study, all the three bands of WiMAX are covered by placing a parasitic element in the vicinity of FMA. Furtheremore, two FMAs and parasitic elements are used in order to anlyze the basic characteristics of MIMO antenna using an electromangnetic simulator. As a result, the 3rd band, 5.5 GHz band...

Design of Multiband Balanced Folded Dipole Antenna Based on a Dual-arm Structure for Mobile Handsets

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...
