A circularly-polarized antenna with broadband based on crlh-tl for navigation applications
A novel circularly-polarized (CP) antenna with Broadband for navigation applications is presented. A circular patch is used as radiator, which is fed by the Wilkinson power divider operating from 1.1 to 2.8GHz. The Wilkinson power divider is designed based on composite right/left handed transmission line (CRLH-TL). The size of the proposed antenna is 0.7λ0 × 0.7λ0 × 0.1λ0 (λ0 is the wavelength at center frequency in free space). The impedance bandwidth for VSWR<2 is 50.9% and the AR bandwidth for AR<3 is 48.57%. Good agreement between simulation and measurement over the desired bands is obtained.
