Abstract:
1. A wide-band internal antenna using a slow-wave structure, the antenna comprising: an impedance matching/power feed part comprising a first conductive element and a second conductive element, the first conductive element extending from a power feed line, the second conductive element separated by a particular distance from the first conductive element and electrically connected with a ground; and at least one radiator extending from the impedance matching/power feed part, wherein the first conductive element and the second conductive element of the impedance matching/power feed part form a slow-wave structure, and the impedance matching/power feed part forming the slow-wave structure has a plurality of first coupling elements protruding from the first conductive element and has a plurality of second coupling elements protruding from the second conductive element, the first coupling elements and the second coupling elements protruding periodically to form a slow-wave structure.
