Portable Communication Device With Ultra Wideband Antenna
First Claim
1. Portable communication device comprising:
- a circuit board having two sides that are at least in an area where they meet at an angle below one hundred and eighty degrees for forming a corner, a ground plane extending between said two sides except for a free area shaped as a triangle at the cornier of the circuit board, a radiating antenna element provided in the free area at the corner, and an electrical connection feeding the antenna across a borderline between the ground plane and the free area.

Abstract
The present invention relates to a portable communication device and an antenna arrangement. The device comprises a circuit board (16) having two sides (26, 28) that are straight, at least in an area where they meet at an angle below one hundred and eighty degrees for forming a corner (30), a ground plane (18) extending between said two sides except for a free area at the corner of the circuit board, and a radiating antenna element (22) provided in the free area at the corner. The antenna arrangement, which comprises the ground plane and the radiating antenna element, is suitable for use in the Ultra Wide Band frequency range while at the same time occupying little space in the portable communication device.

16. Antenna arrangement comprising:
-
a ground plane comprising a section formed as a triangle with a truncated top, which truncated top faced, a tree area shaped as a triangle, a radiating antenna element provided in the free area, which free area when combined with said section of the ground plane forms a complete triangle, and an electrical connection feeding the antenna across a borderline between the around plane and the free area. - View Dependent Claims (17, 18)
