摘要

A frequency-reconfigurable antenna is presented for multiband (GSM850/900/GLONASS1616/rnDCS1800/PCS 1900/UMTS/LTE2300/2500/WLAN) mobile handsetrnapplications. It mainly consists of radiating elements with two PIN diodes. Byrnswitching the ON/OFF states of the PIN diodes, the proposed structure can operate inrnthree states: OFF–ON, ON–OFF, and ON–ON. When PIN diodes are in the OFF–rnON states, the proposed antenna can cover the GSM850/900, PCS1900, andrnUMTS2100 bands by operating in Invented-F antenna (IFA) mode. When PINrndiodes are in the ON–OFF states, the antenna can cover the LTE2300/2500 andrnWLAN2400 bands in monopole mode. Moreover, when PIN diodes are switched tornthe ON–ON states, the designed antenna works in loop mode and its resonant frequenciesrninclude the GLONASS1616, DCS1800/1900, and LTE2500 bands. Withrnthe reconfigurable technique, the proposed antenna achieves a compact size of 15 ×rn28.5 mm~2 with high efficiency from 34% to 84.86% in the total frequency range.
