Abstract

This paper presents a solution to reduce the mutual coupling between two Planar Inverted-F Antennas (PIFAs) working in close frequency bands: DCS1800 (1710-1880 MHz) and UMTS (1920-2170 MHz). The antennas are positioned on the top corner of a ground plane whose size is representative of the Printed Circuit Board (PCB) of a typical mobile phone. Two antenna-systems are designed and several arrangements are studied, especially when suspended line is inserted between the radiators. This line is intended to act as a neutralization device and then reduce the mutual coupling. Several prototypes are fabricated and measured to validate the proposed solution.

Keywords
