MOBILE RADIO APPARATUS
First Claim
1. A mobile radio apparatus comprising:
- a housing;
a circuit board provided in the housing; and
a first antenna element, a second antenna element, and a third antenna element that are placed in one end in the housing and operating in different operation frequency bands;
wherein the first antenna element operates in a first operation frequency band, wherein the second antenna element operates in a second frequency band that is close to the first operation frequency band, wherein the third antenna element operates in a third operation frequency band that is not close to the first operation frequency band or the second operation frequency band and is placed between the first antenna element and the second antenna element in the one end in the housing, andwherein the distance between the end part and a third feeding section for feeding power to the third antenna element is longer than the distance between the one end and a first feeding section for feeding power to the first antenna element and is longer than the distance between the one end and a second feeding section for feeding power to the second antenna element.
