摘要：
The design of several two-port antenna systems for mobile phones is presented. All these structures are made Lip Of two planar inverted-F antennas closely positioned on a small ground plane and radiating in the GSM900/DCS1800 and UMTS frequency bands. First, the antennas are simply associated at the top edge of the same printed circuit board. Thus, to improve their isolation and their total efficiency, a neutralisation effect is created by means of an optimised Suspended line, which links the feeding strips of the radiators. The performance of these systems is measured and compared with theoretical results.
