Abstract :
A compact frequency reconfigurable antenna employing novel composite right/left-hanged (CRLH) transmission line structure is presented. According to the theory of open-ended or short-ended resonators with a CRLH TL, A pin-diode is embedded between the patch and ground. By switching the pin-diode, the antenna can achieve dual-band operation at zeroth-order series and shunt resonances. The antenna is constructed using a Rogers duroid 5880 substrate having the εr value equal 2.2 occupies an overall size of 22.8 × 27 × 1.6 mm3, the working mechanism and radiation performances of the antenna are examined and illustrated for the two operating band.
