Abstract
Provided is a plate-shaped composite material which can sufficiently exhibit an interference effect between antenna elements when utilized as, for example, a substrate of a microstrip patch antenna. The interference effect between the antenna elements can be sufficiently exhibited by controlling the composite material so that, when the material is divided into a plurality of regions, a standard deviation of density values of the respective regions is kept at a certain value or less.
