摘要
A novel design addressing the antenna bandwidth issue for future communication standards on handsets is presented. It consists of a tunable-antenna-pair for operation with a tunable front-end. The antennas are narrow-band and frequency-reconfigurable. This Letter focuses on the low communication bands. Measurements of the design are shown in band 12, and exhibit a receiver-transmitter isolation above 25 dB at 700 MHz.
