Abstract

An antenna arrangement for a portable radio communication device, comprising a first (1) and a second (2) antenna element, and a conductive shield (4) connectable to a ground plane device (3), said first (1) and second (2) antenna elements are located on opposite sides of the shield (4), wherein said first (1) and second (2) antenna elements are of different types.

Claims

1. An antenna arrangement for a portable radio communication device, comprising:

a first (1) and a second (2) antenna element, and

a conductive shield (4) connectable to a ground plane device (3), wherein said first (1) and second (2) antenna elements are located on opposite sides of the shield (4),

characterized in that

said first (1) and second (2) antenna elements are of different types.

2. The antenna arrangement as claimed in claim 1, wherein said antenna arrangement is mountable in said portable radio communication device, such that the shield (4) is essentially perpendicular to said ground plane device (3).

3. The antenna arrangement as claimed in claim 1 or 2, wherein said first (1) and second (2) antenna elements are each adapted to be able to transmit and receive radio signals.

4. The antenna arrangement as claimed in claim 1 or 2, wherein said first (1) antenna element is adapted to be able to transmit radio signals and said second (2) antenna element is adapted to be able to receive radio signals.

5. The antenna arrangement as claimed in claim 1 or 2, wherein said first (1) antenna element is adapted to be able to receive and transmit radio signals and said second (2) antenna element is adapted to be able to receive radio signals.

6. The antenna arrangement as claimed in claim 1 or 2, wherein said first (1) antenna element is adapted to be able to receive and transmit radio signals and said second (2) antenna element is adapted to be able to transmit radio signals.

7. The antenna arrangement as claimed in claim 1 or 2, wherein said first (1) antenna element is adapted to be able to transmit radio signals and said second (2) antenna element is adapted to be able to receive and transmit radio signals.

8. The antenna arrangement as claimed in claim 1 or 2, wherein said first (1) and second (2) antenna elements are each adapted to be able to transmit radio signals.

9. The antenna arrangement as claimed in claim 1 or 2, wherein said first (1) and second (2) antenna elements are each adapted to be able to receive radio signals.

10. The antenna arrangement as claimed in claim 1 or 2, wherein said first (1) antenna element is adapted to be able to receive radio signals and said second (2) antenna element is adapted to be able to receive and transmit radio signals.

11. The antenna arrangement as claimed in claim 1 or 2, wherein said first (1) antenna element is adapted to be able to receive radio signals and said second (2) antenna element is adapted to be able to transmit radio signals.

12. The antenna arrangement as claimed in any of claims 1-11, wherein said first (1) and second (2) antenna elements are mountable within said portable radio communication device.

13. The antenna arrangement as claimed in any of claims 1-12, wherein said first (1) antenna element is one of the following types:

PIFA, meander, loop, patch, dipole, slot, modified PIFA, meander PIFA; and

said second (2) antenna element is one of the following types;

PIFA, meander, loop, patch, dipole, slot, modified PIFA, meander PIFA;

but not the same type as said first (1) antenna element.

14. A portable radio communication device, comprising an antenna arrangement as claimed in any previous claim.

15. The portable radio communication device as claimed in claim 14, wherein said ground plane device (3) is the PCB of the portable radio communication device.
