ANTENNA DEVICE AND MOBILE COMMUNICATION EQUIPMENT PROVIDED WITH THE ANTENNA DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an antenna device by which antenna diversity reception is attained in a contained state where an antenna characteristic is deteriorated in the contained state of an antenna without the need for addition of a new sub antenna and a high diversity effect can be obtained in a speech state when the antenna is mounted on a human body and to provide a mobile communication equipment provided with this antenna system. SOLUTION: An antenna element consists of a 1st antenna element 5 that is projected from a case 3 when the element is contained in the case 3 and of a 2nd antenna element 4 that is placed in the case. When the antenna element is contained in the case 3. An antenna conductor 25 forming a loop antenna with the 2nd antenna element when the antenna element is contained in the case 3 is provided in the case 3. The connection of the 1st antenna element or the 2nd antenna element is switched depending on a radio wave reception state when the antenna element is contained in the case 3.
