Document Type and Number:
Japanese Patent JP3255803
Kind Code:
B2
Abstract:
PURPOSE: To sufficiently miniaturize the main body of a radio equipment by providing a first conducting line connected through a capacitor to a first metal panel and a second conducting line connected to a second metal panel electrically connected with the first metal panel.
CONSTITUTION: This antenna is provided with an antenna element 102 of the first metal panel and an antenna element 103 of the second metal panel. The element 102 is installed on the first face of a dielectric substrate 101, and the element 103 is installed on a second face in counter to the first face of the dielectric substrate. The elements 102 and 103 are mutually electrically connected through a through hole 104 provided on the substrate 101. On the other hand, this antenna is provided with a coaxial table 105. The coaxial table 105 connects its inner conductor through a trimmer capacitor 106 to the element 102 and connects its outer conductor to the element 103.
