Abstract :
In this literature, a novel left-handed circularly polarized voltage-controlled leaky wave antenna is presented with a scanning range of 0°to -37°with a perfect axial ratio at the most time below 2 dB. The structure depends on CRLH (Composite Right/Left Handed) transmission line with a cross finger coupled line added, which gives additional performance on the farfield axial ratio. Also the principle of the structure is discussed and an equivalent circuit is presented for further study.
