Abstract

A novel notch filter is designed and fabricated using novel microstrip, triangle-type resonators. The main advantage of the new notch filter is superior microwave characteristics in increasing the frequency of the third harmonic response, as demonstrated in simulations using fullwave electromagnetic (EM) simulators. The novel notch filter is demonstrated using the following frequency characteristics: central frequency f/sub 0/ = 1.975 GHz, a 3 dB bandwidth of 39.5%, and an insertion loss S/sub 21/ of -54.273 dB. The experimental and simulation results closely correspond to each other. The superior features of the proposed filter make it suitable for use in microwave communication systems and other applications.
