Özet:

 

In this paper, based on a new stub-loaded open loop resonator, a compact   microstrip dual-band bandpass filter is presented. The proposed filter is   designed using two stub-loaded open loop resonators to create two pass bands   at 2.39 GHz and 5.7 GHz for multimode wireless LANs applications. Two high   impedance sections are used in the main loops and the internal stubs are two   low impedance microstrip cells. A method is presented to control the mode   resonance frequencies. By increasing the internal stubs' dimensions, the   resonance frequencies are adjusted without size increment. The proposed   filter has a good performance. The insertion losses at 2.39 GHz and 5.7 GHz   frequencies are 0.1 dB and 0.4 dB, respectively, while the return loss at   the two pass bands is better than -16.6 dB. The filter size is 251   mm22^{2}. The designed filter is fabricated and measured. The results show   that there is a good agreement between the simulation and measurement.
