【 摘 要 】

A frequency reconfigurable antenna array is presented. The array consists of eight arms with two different feed networks. By controlling PIN diode switches, high frequency array with four dipole elements and low frequency array with two dipole elements can be obtained, respectively. Resonant frequencies within the ranges of 1.0–2.5 GHz (Case I) and 2.5–6.0 GHz (Case II) can be achieved, which translates into an overall tuning ratio of 61 (1.0–6.0 GHz) for the antenna array. The proposed antenna array is simulated, fabricated, and tested with good agreement between measurements and simulations.
