Abstract
An antenna device which can be housed within a small portable radio receiver can be obtained by miniaturizing a small loop antenna. A small antenna device is formed by connecting nonlinear first and second conductors to a grounding conductor and connecting these first and second conductors with a third conductor.
Claims10
An antenna device comprising:
- a grounding conductor including a feed portion and a short-circuit portion;
- a first conductor shaped like a nonlinear conductor the one end of which is connected to said feed portion;
- a second conductor shaped like a nonlinear conductor the one end of which is connected to said short-circuit portion;
- and
- a third conductor connected between the other end of said first conductor and the other end of said second conductor.
