Embodiment Construction

[0044] refer to figure 1 , shows an antenna device according to the invention, which is associated with a radio communication device, for transmitting and receiving RF waves, and which comprises a radiating structure 20 on a support 10 . The support 10 is relatively thin, having a thickness ranging from a few tenths of a millimeter to a few millimeters, preferably 0.2-1 millimeter. The support 10 is preferably made of a medium polymeric laminar material comprising strips of material formed into suitable sheets. As shown in the figures, the support is shaped so as to define upwardly curved portions 11 - 13 which bound a substantially planar or very smoothly curved portion 15 . Around the bends 11 - 13 , the support 10 continues in a low inner wall portion 16 . exist figure 1 In , three curved portions 11-13 are shown in order to open one side of the substantially planar or very smooth curved portion 15.

[0045] The support formed from the layered material is preferably a r...

Abstract

An antenna device for transmitting / receiving RF waves to be arranged in a radio communication device, comprising: a carrier (10) having first and second surfaces carrying a radiating structure (20) on the first surface; a feed portion (25) being connectable to transceiver circuits of the radio communication device and being arranged on the carrier (10) and forming a part of the radiating structure (20); and a ground plane means. The carrier has curved portions (11-13), whereof at least two meet each other. Further a method for manufacturing an antenna device and a hand portable radio communication device, including an antenna device are disclosed.

Description

technical field [0001] The present invention relates to an antenna device for transmitting / receiving RF waves, the antenna device is arranged in a radio communication device, it comprises: a support with a first and a second surface, with a radiating a structure; a feed portion connectable to a transceiver circuit of the radio communication device, the feed portion being arranged on the support and forming part of the radiating structure; and a grounding device. The invention also relates to a device for producing such an antenna. Furthermore, the invention also relates to a radio communication device comprising such an antenna device. Background technique [0002] In today's radio communication systems, there is an increasing demand for the availability and smaller size of subscriber units. This requires the antenna device to be compact and have good antenna performance. An antenna arrangement including a helical element combined with an extendable whip antenna is used i...
