Surface-Mount Antenna and Radio Communication Apparatus Including the Same
First Claim
1. A surface-mount antenna for being connected to a radio-communication high-frequency circuit to operate as an antenna, comprising:
- a radiation electrode formed on a base member, wherein one end of the radiation electrode serves as a feeding portion for being connected to the radio-communication high-frequency circuit, and the other end of the radiation electrode is an open end, the radiation electrode having a width which increases from the feeding portion toward the open end, a band-like feeding electrode formed on the base member and connected to the feeding portion of the radiation electrode to serve to connect the feeding portion to the radio-communication high frequency circuit, and a ground electrode formed on the base member and disposed on at least one side of the feeding electrode so as to define a spacing with the feeding electrode, and the spacing between the ground electrode and the feeding electrode is smaller than a width of the feeding electrode.

Abstract
A surface-mount antenna, in which a radiation electrode to be connected to a radio-communication high-frequency circuit to operate as an antenna is formed on a base member 2. One end of the radiation electrode serves as a feeding portion for being connected to the radio-communication high-frequency circuit, and the other end of the radiation electrode is an open end. The radiation electrode includes a portion whose width is increased as it goes from the feeding portion toward the open end. The base member includes a band-like feeding electrode connected to the feeding portion of the radiation electrode to serve to connect the feeding portion to the high frequency circuit, and a ground electrode disposed on one side or both sides of the feeding electrode with a defined spacing between the feeding electrode and the ground electrode. The spacing between the ground electrode and the feeding electrode is set to be smaller than the width of the feeding electrode.
