Abstract :
A linearly-polarized agile antenna fed by two cascaded tunable quasi-lumped quadrature couplers is proposed. The whole coupler circuit has the ability to change the amplitude level ratio of its two outputs from -30 dB to +15 dB with the help of varactor diodes. The rotation of the linearly-polarized electrical field of the antenna is achieved over a 90deg angle using the tuning capability of the coupler.
