Abstract:

In this paper, a new miniature microstrip bandpass filter using aperture-coupled hairpin resonators is presented. The proposed filter is composed of five U-shaped hairpin resonators located on two stacked microstrip layers. The different couplings between the resonators on the upper layer and those on the lower one are achieved via two aperture etched on a common ground plane located between the two layers. A full-wave simulator is used to design the proposed structure and determine the dimension of the apertures. As a result, a five-pole hairpin bandpass filter was designed and optimized at 2.45 GHz. The use of this multilayer technique allows a significant size reduction of about 40 %.
