Abstract
An optically transparent coplanar microwave slot antenna is provided including a conductive mesh and a feedline connectively coupled to the conductive mesh wherein the conductive mesh includes a plurality of Christmas tree shaped slots arranged in a dipole configuration wherein each of the plurality of Christmas tree shaped slots is formed from a triangular slot, a trapezoidal slot and a rectangular slot.
Claims20
An antenna comprising:
- a conductive mesh;
- and
- a feedline connectively coupled to the conductive mesh, wherein the conductive mesh includes a first Christmas tree shaped slot and a second Christmas tree shaped slot wherein the first Christmas tree shaped slot is formed by a triangular slot, a trapezoidal slot and a rectangular slot.
A dipole slot antenna comprising:
- a conductive mesh having an upper portion and a lower portion wherein the upper portion is separated from the lower portion by a first element of the dipole slot antenna and a second element of the dipole slot antenna, wherein the first element of the dipole slot antenna is formed from a triangular slot, a trapezoidal slot, and a rectangular slot and wherein the second element of the dipole slot antenna is a mirror image of the first element of the dipole slot antenna around a first axis;
- and a feedline for coupling a microwave signal to the conductive mesh.
A coplanar slot antenna comprising:
- a rectangular conductive mesh;
- a first slot element and a second slot element formed in a dipole arrangement within the rectangular conductive mesh wherein the first slot element is formed by a first triangular slot, a first trapezoidal slot, and a first rectangular slot and the second slot element is formed by a second triangular slot, a second trapezoidal slot, and a second rectangular slot;
- and
- a feedline for coupling a microwave signal to the rectangular conductive mesh.
