Q-factor and bandwidth of periodic antenna arrays over ground plane
Andrei Ludvig-Osipov, B. L. G. Jonsson
In this paper, the Q-factor expression for periodic arrays over a ground plane is determined in terms of the electric current density within the array's unit cell. The expression a…

Stored energies and Q-factor of two-dimensionally periodic antenna arrays
Andrei Ludvig-Osipov, B. L. G. Jonsson
The Q-factor for lossless three-dimensional structures with two-dimensional periodicity is here derived in terms of the electric current density. The derivation in itself is shape-…
