摘要：
In this paper, a frequency reconfigurable self-oscillating active integrated antenna (AIA), realized by a metamaterial resonator, a feedback oscillator and a pair of PIN diodes, is proposed and experimentally demonstrated. By switching on and off the PIN diodes bridging the shunt inductance, the resonator can be operated either as a composite right-/left-handed (CRLH) resonator or a mu-negative material (MNG) resonator, both operating in the +1 mode. The resonator functions as the frequency-selective element of the oscillator, thereby determining the oscillating frequency of the AIA in the two states. The design principle and experimental results will be discussed.
