Microstrip Bandpass Filter with Slotted Hexagonal Resonators and Capacitive Loading

A compact microstrip elliptic-function bandpass filter (BPF) is introduced in this article. The techniques, etching slot and adding open stubs with capacitive loading, are applied to enhance the self-inductance and self-capacitance of the hexagonal ope...
Modern mobile systems impose strict requirements for bandpass filters, such as small size, high selectivity, wide upper stopband, low insertion loss and cost. A planar microstrip elliptic-function BPF is a good choice for this purpose. BPF advances on the base of circular, square and triangular patch/ring resonators have been...
