Abstract
Official abstract text for this publication.
An antenna unit and a radio communication device are provided. An antenna unit has a monopole antenna section and a loop antenna section. The monopole antenna section includes a linear radiating electrode that resonates at a first frequency and has an electrical length of one-quarter of the wave length corresponding to the first frequency. The loop antenna section includes a radiating electrode that resonates at a second frequency, is vertically erected on a non-ground region, and connected to a feed line. A proximal end of the radiating electrode of the loop antenna section is connected to an intermediate portion of the feed line, and a distal end thereof is connected to a ground region. The electrical length of the radiating electrode of the loop antenna section is one-half of the wave length of the second frequency.
First claim
Opening claim text (preview).
That which is claimed is: 1. An antenna unit comprising: a single feed line extending from a feed section onto a non-ground region of a surface of a board; a monopole antenna section including a radiating electrode having a linear shape, the radiating electrode being provided on the non-ground region and including a proximal end and distal end, the proximal end of the radiating electrode being connected to a distal end portion of the feed line and the distal end of the radiating…
