摘要：

In this communication, a balanced frequency-reconfigurable antenna for nine-band operation covering GSM 850/900/1800/1900/UMTS2100/LTE700/2300/2500 /WLAN2400 bands for multiradio mobile platforms is presented. The antenna consists of simple planar geometry with size of 60 x 15 mm(2) that is quite practical for implementation on current consumer-type multiradio mobile platforms. The design comprises of a feeding strip and an electromagnetically coupled parasitic shorted strip whose effective length is electronically controlled through a single PIN diode. By combining both ON and OFF states of the PIN diode, four resonance modes are achieved covering nine bands of LTE/WWAN/WLAN operation. The proposed antenna is successfully simulated, fabricated and measured. It has excellent radiation efficiency and positive gains over all nine bands of operation.
