Abstract
Presented is a new dual-band differential quadrature divider with asymmetric structure operating at GPS L1 and L2 bands (1575 and 1227 MHz) for circularly polarised (CP) antennas and RF transceivers. The proposed structure is composed of one ring hybrid coupler and two Wilkinson dividers with three λ/4 short stubs. Each circuit is designed asymmetrically for dual-band characteristics.
