Mutual Coupling Reduction between Very Closely Spaced Microstrip Antennas Using CPW Structure

MATEC Web of Conferences, 2016
An efficient H-plane mutual coupling reduction method is introduced for very closely placed dual-element microstrip antennas operating at 2.4GHz. A simple coplanar waveguide (CPW) structure is introduced in the ground, energy from one element is guided ...

Mutual Coupling Reduction between Patch Antennas Using Meander Line

International Journal of Antennas and Propagation, 2018
Meander lines (MLs) in two configurations are presented to reduce the mutual coupling (MC) between two microstrip patch antenna elements. Inserting a slot in the ground plane between the antenna elements is a simple method to reduce the MC, while adding ...

Cumulant-Based DOA Estimation of Noncircular Signals against Unknown Mutual Coupling

Sensors, 2020
To effectively find the direction of non-circular signals received by a uniform linear array (ULA) in the presence of non-negligible perturbations between array elements, i.e., mutual coupling, in colored noise, a direction of arrival (DOA) estimation ...

Relativistic Modification of the Gamow Factor [PDF]

, 1999
In processes involving Coulomb-type initial- and final-state interactions, the Gamow factor has been traditionally used to take into account these additional interactions. The Gamow factor needs to be modified when the magnitude of the effective coupling

Offset fields in perpendicularly magnetized tunnel junctions

, 2019
We study the offset fields affecting the free layer of perpendicularly magnetized tunnel junctions. In extended films, the free layer offset field results from interlayer exchange coupling with the reference layer through the MgO tunnel oxide.
