Abstract

In one embodiment, an integrated antenna and display shade for a wireless portable control unit is provided which includes a stowable display shade having two side panels and a front panel between the two side panels. Each of the two side panels are foldably connected to opposing edges of the front panel so as to be capable of folding into planes generally parallel with a plane of the front panel when stowed and into planes generally orthogonal to the plane of the front panel when deployed to shade a visual display. The front panel includes an active antenna and each of the side panels include a parasitic antenna.

Claims

1. An integrated antenna and display shade for a wireless portable control unit comprising:

a) a stowable display shade comprising two side panels and a front panel between the two side panels, each of the two side panels being foldably connected to opposing edges of the front panel so as to be capable of folding into planes generally parallel with a plane of the front panel when stowed and into planes generally orthogonal to the plane of the front panel when deployed to shade a visual display;

b) the front panel comprising an active antenna; and

c) each of the side panels comprising a parasitic antenna.

2. The integrated antenna and display shade of claim 1, wherein the active antenna is a dipole antenna.

3. The integrated antenna and display shade of claim 2, wherein the active antenna further comprises a sleeve.

4. The integrated antenna and display shade of claim 3, wherein each of the parasitic antennas further comprise a sleeve.

5. The integrated antenna and display shade of claim 2, wherein the front panel comprises a front face and a back face, and wherein the dipole antenna comprises a portion on the front face and a portion on the back face.

6. The integrated antenna and display shade of claim 2, wherein the parasitic antennas are dipole antennas.

7. The integrated antenna and display shade of claim 6, wherein each of the parasitic antennas further comprise a sleeve.

8. The integrated antenna and display shade of claim 6, wherein each dipole antenna has portions on both planar surfaces of its corresponding front or side panel.

9. The integrated antenna and display shade of claim 1, wherein the active dipole antenna and the parasitic antennas comprise portions on opposite planar surfaces of their corresponding front or side panel.

10. The integrated antenna and display shade of claim 1, wherein the front panel and side panels are configured such that the front panel is tilted toward the visual display such that the active antenna provides an elevated antenna pattern when the stowable display shade is deployed to shade the visual display.

11. A portable directional antenna structure for a wireless portable control unit comprising:

a) a foldable panel structure comprising two side portions and a front portion between the two side portions, each of the two side portions being foldably connected to opposing edges of the front portion so as to be capable of folding into a plane generally parallel with a plane of the front portion when stowed and into planes generally orthogonal to the plane of the front portion when deployed as a directional antenna;

b) the front portion comprising at least one active dipole antenna; and

c) each of the side portions comprising at least one parasitic dipole antenna.

12. The portable direction antenna structure of claim 11, wherein the front portion is tilted back from normal such that the directional antenna provides an elevated antenna pattern when deployed.

13. The portable direction antenna structure of claim 11, wherein the at least one active antenna further comprises a sleeve.

14. The portable direction antenna structure of claim 13, wherein each of the parasitic antennas further comprises a sleeve.

15. The portable direction antenna structure of claim 11, wherein the at least one active dipole antenna and each of the at least one parasitic antennas comprise portions on opposite planar surfaces of their corresponding front or side portions.
