| Abstract: | A new dual-band microstrip filter based on square ring and loaded stub is proposed.The center frequencies of its low-band and highband can be easily adjusted by the dimensions of the square ring and loaded stub.Then the simulations are carried out and the experimental prototype is also made.The measured center frequencies of the optimized filter are 2.365 GHz and 4.465 GHz,and the insertion loss is lower than 3 dB.A basic agreement between the simulated and the measured results is obtained.The presented fil... |
