发明名称 SLOT ANTENNA
摘要 PROBLEM TO BE SOLVED: To provide a slot antenna capable of easy impedance adjustment. SOLUTION: A slot antenna 20 is provided, which consists of a power feeding element 34 and a slot 30 opened so as to have a length substantially half wavelength of a desired reception radio wave on a defogger provided on a vehicle glass. Also, the power feeding element 34 consists of a first conductor 34a arranged inside a slot opening and extending in a slot longitudinal direction in substantially parallel, a second conductor 34b connected to the first conductor 34a at substantially right angles, and a third conductor 34c extending in substantially parallel to the slot longitudinal direction and substantially perpendicularly to the second conductor 34b. Power feeding to the slot 30 is performed by providing a gap near the second conductor 34b or the third conductor 34c or a connection portion between the second conductor 34b and the third conductor 34c.
