摘要： It is made possible to realize both miniaturization and a wider band in an antenna element. An antenna element includes a first conductor wire part 11A; a second conductor wire part 11B crossing the first conductor wire part 11A and connected; a third conductor wire part 11C crossing the second conductor wire part 11B and connected, and parallel to the first conductor wire part 11A; a fourth conductor wire part 11D crossing the third conductor wire part 11C and connected; and a first conductor flat plate 12 connected to one or two of the first conductor wire part 11A, the second conductor wire part 11B, the third conductor wire part 11C, and the fourth wire part 11D and disposed in the area surrounded by any three of the first conductor wire part 11A, the second conductor wire part 11B, the third conductor wire part 11C, and the fourth wire part 11D. An end part of the first conductor flat plate 12 is parallel with the first conductor 11A not connected to the first conductor flat plate 12.

摘要： A polarization switching antenna device capable of switching a polarization without increase of an antenna installing space and also handling a variety of frequency bands is provided. A connection state of one end of a loop antenna element arranged on a side surface of a case is switched. Thus, the polarization characteristic is switched by switching selectively whether the antenna element should constitute a loop antenna or a linear antenna. Matching circuits suitable for respective characteristics are provided. The loop antenna can be fed in terms of a balanced feeding. A balanced feeding and an unbalanced feeding can be switched.
