Abstract:
A uniplanar dual strip antenna comprising a first electrically conductive metallic strip and an electrically conductive metallic second strip mounted on a single face of a dielectric substrate, said first and second strips being spaced from each other by a selected constant gap, wherein the length and the width of said first and second strips are selected such that they form a two wire transmission line for receiving and transmitting electromagnetic energy, further comprising a coplanar waveguide having a positive and a negative terminal, said coplanar waveguide being formed by disposing metal on the same face of said substrate, the positive terminal being electrically coupled to said first strip and the negative terminal being electrically coupled to said first and second strips, wherein surface currents are formed on said first and second strips when said uniplanar dual strip antenna is energized by electrical signals via said coplanar waveguide.
