ABSTRACT:
A portable radio receiver with a built-in antenna includes first and second housing sections made of a dielectric having a high dielectric constant, an antenna conductor disposed in an internal space between the two housing sections, and an apparatus board to be connected to the antenna conductor. The antenna conductor is formed as a loop antenna. A recessed portion is formed in the joint surface of the first housing section. A groove for accommodating the loop antenna is formed at a deep end in the inner wall of the recessed portion. A projecting portion to fit in the recessed portion is formed on the joint surface of the second housing section. When the recessed and projecting portions are fitted with each other, the two housing sections form one integral body, and the loop antenna is sandwiched between the recessed and projecting portions.
