| () |
| Abstract: |
| A minitype directional coupler is designed using a novel spiral broadside coupled structure.The return loss and isolation are improved by compensating capacitance.The coupler is simulated and optimized by using 3D electromagnetic analyzing software,more than 25dB return loss and isolation is obtained in 600~900 MHz,and the test result of the experimental sample is in agreement with the simulated result. |
| Key words: microwave circuit,directional coupler,spiral broadside coupled structure,capacitor compensation |
