Abstract
A combination antenna and radio communication device comprises a dielectric base ( ) on which a multislot antenna ( ) made of conductor, a coplanar transmission line ( ), a power supply line, and a high-frequency unit ( ) are provided. A conductive package ( ) and the dielectric base ( ) hermetically seal the high-frequency unit ( ), the coplanar transmission line ( ), and the multislot antenna ( ). The lower face of the dielectric base ( ) faces to a conductive sheet ( ) having an opening ( ) for passing therethrough electromagnetic waves. Electromagnetic waves are passed through the dielectric base ( ) and taken out through the opening ( ). Therefore the combination antenna and radio device for pseudo-millimeteric and millimeteric waves have a small size, high performance and excellent massproductivity.
