| Appl. No: | 08/626,091 |
| Application Filed: | April 03, 1996 |
| Abstract: | The receiver which comprises a flat picture screen (20) has an antenna which comprises two articulated main plates (4, 5) symmetrically disposed on either one of the two sides of the screen, and forming an angle with each other, as well as two plates (2, 3) parallel with the screen and symmetrical to each other relative to the median vertical plane (19) of the screen. |

| Claim: | What is claimed is |
| Claim: | 1. Portable receiver with an antenna for receiving electromagnetic waves, comprising a box which accommodates an electronic circuit, characterized in that the antenna comprises for an application in the UHF frequency range |
| Claim: | two electrically conductive main plates, each attached along a line on the exterior and on either one of the two sides of the box, practically symmetrically |
| Claim: | and two parallel plates, which are practically triangular with their points turned to each other and which are contained in the same symmetric plane with respect to each other, and which are connected by one of their edges to the edge turned towards the box of each of the main plates |
| Claim: | and a slewability is provided in the connection line of each main plate and, in the position of use, the main plates and the parallel plates form an angle between them. |
| Claim: | 2. Portable receiver as claimed in claim 1, characterized in that the distance measured along the main plates and the parallel plates of the antenna between the ends that are remotest from each other of the two main plates is of the order of a wavelength of a receiving frequency. |
| Claim: | 3. Portable receiver as claimed claim 1, characterized in that the parallel plates which are practically triangular have each a pattern that is dissymmetrical relative to a horizontal axis. |
| Claim: | 4. Portable receiver as claimed in claim 1, characterized in that the main plates and the box advantageously have practically the same maximum dimension in a direction parallel with the connecting line of a plate. |
| Claim: | 5. Portable receiver as claimed in claim 1, characterized in that a parallel plate is connected to a main plate via a transition plate which forms an angle both to the main plate and to the parallel plate. |
| Claim: | 6. Portable receiver as claimed in claim 1, characterized in that the main plates and the parallel plates are made of plastic material and are coated by a soft metallized foil. |
| Claim: | 7. Portable receiver as claimed in claim 1, characterized in that it is a picture receiver with a picture screen. |
| Claim: | 8. Portable receiver as claimed in claim 7, characterized in that the practically triangular parallel plates are placed behind the receiver. |
| Claim: | 9. Portable receiver as claimed in claim 7, characterized in that the practically triangular parallel plates leave between their points a space that is sufficient for placing the picture screen there. |
