Design and implementation of hybrid ring coupler for 800MHz–1200 MHz
A novel wide band hybrid ring coupler is proposed in this paper. The change in length of transmission line is calculated and it is converted in to equivalent impedance. Impedance of the circuit is varied using variable capacitor. The device is to be fabricated and tested for frequency range 800-1200MHz. The circuit shows improved isolation and return loss. The circuit is reduced by using Koch fractal curve method. The results for both conventional and the reduced Koch hybrid coupler are simulated and the results are compared.
