1. A surface-mount type antenna comprising:
- a base body made of a rectangular parallelepiped dielectric or magnetic material,the base body including two opposed side surfaces, two opposed principal surfaces, anal two opposed end faces,the four surfaces each having a first end side part on the same end side part of each surface and a second end side part opposite the first end side part, a first end face on the first end side part of the base body and a second end face on the second end side part of the base body;
a feeding terminal formed at one end of one side surface of the base body; and
a radiating electrode,wherein one end of the radiating electrode is connected to the feeding terminal, and wherein the other end of the radiating electrode is routed from a first end side part of a first side surface, through a first end side part of a first principal surface of the base body, through a first end side part of the second side surface, and thereafter along a route selected from the group consisting of;
(1) to a second end side part of the second side surface through the second end side part of the second side surface and to the second end side part of the first principal surface,(2) to a second end side part of the second side surface, through the second end side part of the second side surface, through a second end side part of the first principal surface and further to a second end side part of the first side surface, and(3) to a second end side part of the second side surface, through the second end face on the second end side part and then to a second end side part of a second principal surface, andwherein the radiating electrode further extends from the second end side part selected from the group consisting of the second end side part of the first principal surface, the second end side part of the first side surface, and the second end side part of the second principal surface to the first end side part so as to be parallel to a ridge of the base body, andwherein a radiating electrode terminating portion which is the other end of the radiating electrode, is formed as an open end, and the radiating electrode terminating portion is further formed to be short so as to fail to reach the first end side part.

Abstract
An surface-mount type antenna includes a rectangular parallelepiped base body, a feeding terminal formed at one-end-side part of one side surface thereof, and a radiating electrode, to one end of which is connected the feeding terminal, disposed such that its other end is routed from one-end-side part of one side surface, through one-end-side part of one principal surface, to another-end-side part of one principal surface, and extends from the other-end-side part to the one end side part parallelly with a ridge of the base body, and is eventually formed into an open end. An antenna apparatus is constructed by mounting the surface-mount type antenna on a mounting substrate having a feeding electrode and a ground conductor layer with a linear side edge located near the feeding electrode, with the ridge of the base body arranged parallel to the linear side edge of the ground conductor layer.
