Watch type paging receiver

A wristwatch type pager including a belt, comprising:

• a body accommodating a receiving circuit and supported by said belt;
• display means provided on said body for displaying information received by said receiving circuit;
• a main antenna formed as a part of the structural members of said display means;
• wherein said belt comprises a loop antenna;
• and
• said pager further comprises antenna matching circuit means coupled to said receiving circuit and to said loop antenna and having an adjustable matching capacitance for matching the loop antenna of said belt to said receiving circuit, said capacitance changing in accordance with the length of said belt.

A wristwatch type pager with a body and a belt, comprising:

• receiving circuit means accommodated in the body;
• loop antenna means to be coupled to said receiving circuit means;
• first connecting means coupled to said loop antenna means and representing the length of the belt;
• antenna matching circuit means for matching said loop antenna means to said receiving circuit means;
• and
• second connecting means connected to said first connecting means and to said antenna matching circuit means, the resonant frequency of said antenna matching circuit means being determined by the connection of said first and second connecting means.
