1. A communication device comprising:
- a circuit board including a first side and a second side that are substantially straight in at least a first area in which the first and second sides meet to form a corner at an angle of less than 180°
;
a ground plane extending between the first and the second sides except in a second area of the corner of the circuit board;
a radiating antenna element provided in the second area, where the first and second side of the second area have lengths greater than ¼
of a wavelength of a lowest frequency of a band of operable frequencies associated with the radiating antenna element; and
an electrical connection to feed the radiating antenna element across an interface between the ground plane and the second area.

Abstract
A communication device is provided, which includes a circuit board having first and second sides that are substantially straight in the area in which the first and second sides meet to form a corner at an angle of less than 180°; a ground plane extending between the first and the second sides, except in a particular area of the corner of the circuit board; a radiating antenna element disposed in the particular area; and an electrical connection to feed the radiating antenna element across an interface between the ground plane and the particular area.

15. An antenna arrangement comprising:
-
a ground plane including a first side and a second side and forming a triangular-shaped section having a truncated top facing a free area shaped as a triangle; a radiating antenna element provided in the free area, where the free area together with the triangular-shaped section of the ground plane forms a complete triangle; and an electrical connection to feed the radiating antenna element across an interface between the ground plane and the free area, where the first and second side of the free area have lengths greater than ¼
of a wavelength of a lowest frequency of a band of operable frequencies associated with the radiating antenna element. - View Dependent Claims (16, 17)
