Abstract

A multi-resonance feed structure for exciting a mobile handset antenna in order to achieve multiband operation is presented. The feed structure adjusts its impedance and controls the coupling with the antenna structure. Based on the proposed feed structure, the dimensions allowed for the antenna design are only 10 × 55 × 2 mm ³ while the measured impedance bandwidth is from 694 to 1003 MHz in the lower band and from 1656 to 2772 MHz in the higher band under a voltage standing wave ratio of 3:1 with good measured realized efficiency. The proposed antenna is a competitive candidate that fully covers most 4th generation (4G) and existing wireless communication services.
