SLOT ANTENNA HAVING INDEPENDENT ANTENNA ELEMENTS AND ASSOCIATED CIRCUITRY

摘要

A slot antenna has independent antenna elements (120,130). A multilayer dielectric substrate (110) has a conductive layer (115). A pair of coplanar elongated slots (123,133) is formed in the conductive layer and configured in a substantially collinear fashion with one another. A pair of transmission lines of conductive traces (125,135) is formed on the multilayer dielectric substrate coupled to a respective slot. Preferably the pair of slots is notches configured in directions opposing one another. In a further aspect of the invention an additional slot (253) is formed in the conductive layer (215) between the pair of the slots (223,233) and an additional transmission line (255) of a conductive trace is formed on the multilayer dielectric substrate (215) and coupled thereto. For polarization diversity, the another slot can be configured orthogonally relative to the pair of the slots. Associated application circuitry (140,150,160) can be disposed on the same dielectric substrate as the antenna element.
