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.
