ANTENNA UNIT AND RADIO COMMUNICATION DEVICE |
摘要 |
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.
