Abstract
A novel design of a compact multilayer resonator is proposed using a double-sided microstrip. This resonator consists of
two quasi-lumped elements: a square spiral inductor and a microstrip patch capacitor. Each quasi-lumped element is
printed on different layers – the upper and the lower dielectric layer separated by a common ground plane. The maximum
dimension of this resonator is less than 25 g , where g is the guided wavelength of a 50 microstrip line at the
resonant frequency. The design methodology is exemplified by a second-order multilayer bandpass filter that is based on
the proposed resonator. The filter is fabricated and measured, and the simulated and measured results are in agreement..
