Circularly polarized U-Slot antenna

, 2007
Circularly polarized single-layer U-slot microstrip patch antenna has been proposed. The suggested asymmetrical U-slot can generate the two orthogonal modes for circular polarization without chamfering any corner of the probe-fed square patch microstrip ...

Novel 3D Hilbert microstrip resonators

, 2005
Recently, planar microstrip resonators employing 2D Hilbert curves were introduced, outperforming existing solutions. However, very little attention has been paid to multilayer resonators with embedded 3D curves.

Crossovers in microstrip

Electronics Letters, 1978
The fabrication and characterisation of a crossover structure in microstrip is described. The results indicate the means to achieve either high isolation between physically intersecting signal paths, or a controlled amount of coupling for applications where this is desirable.

A Compact Lowpass Filter with Ultra Wide Stopband using Stepped Impedance Resonator [PDF]

Radioengineering, 2017
In this paper, a compact asymmetric-shaped microstrip lowpass filter (LPF) using a stepped impedance resonator is presented. An ultra wide stopband with high attenuation in the stopband region, within very small circuit area is achieved for the proposed ...

Parameters of microstrip

Electronics Letters, 1969
The program computes the capacitance, effective permittivity, characteristic impedance and phase velocity of single strips, and of the normal modes of coupled pairs of strips, in an approximation in which the longitudinal components of the fields and the thickness of the conducting strips are neglected.
