Dual-Band Pass Filter with Wide Band-Frequency Rejection
A Dual band Filter block has been highly attention due to its highly importance in wireless communication systems. High frequency level normally companies with the performance of filter block. The use of both low-pass or band-stop filter and the step-impedance lines methods to reduce the spurious characteristics of the filter are not a practical solution since that adds more complexity and large in size. The proposed microstrip filter was utilized for Industrial Scientific and Medical (ISM) applications (2.45 GHz) with -25 dB with twice transmission zeroes as a first band while the second band of (3.5-8 GHz) for LTE and wireless LAN applications with return loss up-to -15 dB. (CST) Computer Simulation Technology was used to simulate the declared structure. The dual band, mode simulation results have been extracted and also compared with the literature that get closed to each other. So that, the computer aided design gives a good pointer to adopt an extracting result that have been obtained using the aforementioned simulator.
