Abstract
Abstract A combination antenna and radio communication device comprises a dielectric base ( 10 ) on which a multislot antenna ( 101 ) made of conductor, a coplanar transmission line ( 102 ), a power supply line, and a high-frequency unit ( 104 ) are provided. A conductive package ( 105 ) and the dielectric base ( 103 ) hermetically seal the high-frequency unit ( 104 ), the coplanar transmission line ( 102 ), and the multislot antenna ( 101 ). The lower face of the dielectric base ( 103 ) faces to a conductive sheet ( 107 ) having an opening ( 106 ) for passing therethrough electromagnetic waves. Electromagnetic waves are passed through the dielectric base ( 103 ) and taken out through the opening ( 106 ). Therefore the combination antenna and radio device for pseudo-millimeteric and millimeteric waves have a small size, high performance and excellent massproductivity.
