Abstract
A stereoscopic antenna includes a planar electroconductive pattern,adapted to be grounded, a loop-shaped antenna body,having an axis C,lying perpendicular to the planar electroconductive pattern,and an antenna connection,for connecting the antenna body,to the planar electroconductive pattern,In this stereoscopic antenna, the ratio H/D of the longer diameter D of the antenna body,relative to the height H of the antenna body,as measured from the planar electroconductive pattern,is chosen to be within the range of 0.1 to 1. By making the antenna to have a three-dimensional structure different from any of the loop antenna and the rod antenna, the stereoscopic antenna compact in size can be obtained having a uniform field radiation pattern and giving rise to an increased gain.
