Abstract

This paper presents a quasilumped microstrip structure highpass filter having a cutoff frequency 1.5 GHz. The quasilumped elements used for this design have their size smaller then the quarter of the guided wavelength at the operating frequency. The proposed designs is a three pole filter, consisting of short circuit stub transmission line and inter digital capacitors on a commercial substrate having relative dielectric constant 4.7 and 1.6 mm of thickness. A sample filter is designed based upon the theory presented and it has been simulated with the S-parameters using IE3D software.
