Provided is an inverse-L shaped antenna that has a shape suited for making the size of the antenna compact, making impedance matching easy, and achieving high-gain. The inverse-L shaped antenna is configured to be provided with: a grounding conductor face (10) provided on the front-side or back-side, and having a ground electric potential; an outer conductor (26) that has the base-end section (21) thereof connected to a prescribed section of that grounding conductor face (10); and an inner conductor (24) that is surrounded by that outer conductor (26), arranged so as to have a gap between the inner conductor and the outer conductor (26), and that has the tip thereof elongating further than the outer conductor. The inverse-L shaped antenna is also configured so that the outer conductor (26) and the inner conductor (24) are bent at a place (22) separated at a prescribed distance from the place where the conductors are connected to the grounding conductor face (10), then arranged in proximity and parallel to the grounding conductor face (10), and so that electricity is fed to the inner conductor (24). |
