Abstract
An antenna includes a substrate layer having a first surface and an opposite second surface, the second surface having a metallization layer; a conductive layer disposed on the first surface of the substrate layer; a slot formed in the conductive layer, the slot including a first part and a second part that are symmetric to each other about a diagonal of the conductive layer; and at least one feed point on the conductive layer and spaced from the slot by a predetermined distance.
Claims19
An antenna, comprising:
- a substrate layer having a first surface and an opposite second surface, the second surface having a metallization layer;
- a conductive layer disposed on the first surface of the substrate layer;
- a slot formed in the conductive layer, the slot comprising a first part and a second part that are symmetric to each other about a diagonal of the conductive layer;
- and
- at least one feed point on the conductive layer and spaced from the slot by a predetermined distance,
- wherein the at least one feed point is positioned off horizontal, vertical, and diagonal center lines of the conductive layer, and
- wherein at least one portion of the conductive layer is selectively removed to tune at least one of two resonant frequencies provided by the antenna.
