Reflected Group Delay of a Capacitively Coupled Resonator for Characterization of Dielectric Constant and Loss Tangent of Microstrip Substrates

IEEE Access
This paper presents a novel method to determine dielectric constant and loss tangent of substrates used in microstrip circuits. The method is based on the reflected group delay of a microstrip resonator coupled to the input by means of an interdigital ...

Feeding‐line‐based decoupling patch antennas

IET Microwaves, Antennas & Propagation
Mutual coupling among multiple antennas has been a problem needed to be tackled in multiple‐input‐multiple‐output (MIMO) systems. A decoupling method based on short decoupling feeding lines (DFLs) for MIMO patch antennas is proposed.

Equivalent circuits for an electrically thick square patch directly fed by a coaxial probe or by a microstrip line [PDF]

, 1988
The authors present lumped-element equivalent circuits for two specific square patches on an electrically thick (0.05 λ0) substrate. The equivalent circuits were derived from experimental data and could be useful in the verification of theoretical ...
