Abstract
A planar antenna has an active circuit block, the whole or part of which is internally mounted to a planar antenna body so that connecting terminal of the block will be connected to a feeding point on power supply plate of the antenna body. Dimensional minimization of the entire antenna can be thereby attained and noise figure of the active circuit can be simultaneously reduced.
