Problems solved by technology

When doing this, if the antenna is not shielded or placed at an appropriate distance, the antenna assembly can deleteriously affect the part, the shielding is expensive, and if the part is another type of antenna, the shielding can damage the part's Function
components can also detrimentally affect antenna characteristics
The greater distance of the components from the antenna unit results in bulky equipment, which is often also undesirable

Embodiment Construction

[0040] A portable communication device according to the invention is now described for a cellular telephone as a preferred variant of the invention. The portable communication device may be another type of device such as a cordless telephone, communication module, PDA or any other type of portable device that communicates with radio waves.

[0041] Figure 1 schematically shows a front view of a cellular telephone 10 according to the present invention. The phone 10 includes a display 12 and a keypad 14 provided on the phone's housing. It's worth mentioning here that there is no antenna protruding from the phone. Antenna is built in.

[0042] Fig. 2 schematically shows a top view of an antenna arrangement provided for communication in at least one frequency band, such as the GSM band, provided inside the housing 16 of the telephone. The antenna arrangement comprises a first antenna element 18 which is formed like a flat plate extending over most of the length of the phone and...

Abstract

A portable communication device includes a radio circuit for feeding antenna elements, at least one component which is mildly sensitive to external radio transmission, and an antenna arrangement for sending and receiving radio traffic. The antenna arrangement includes a first antenna element located within and extending through a major portion of the device, and a second smaller antenna element connected to the first antenna element. The radio circuit is connected between the two antenna elements and the component is provided on a section of the antenna arrangement making small contributions to the antenna currents in the antenna arrangement.

Description

technical field [0001] The present invention relates to the field of antennas and more particularly to a portable communication device having an antenna arrangement provided within a housing of the device. Background technique [0002] In the field of portable communication devices, especially cellular phones, there is a tendency to have built-in antennas in cellular phones. [0003] One such built-in antenna arrangement is described in WO-0237600. Here, a cellular phone is described having an antenna arrangement provided within a housing of the phone. The antenna arrangement consists of a first antenna element in the form of a shield, casing or frame of the telephone and is equipped with a second antenna element provided at one end of the first antenna element serving as a grounding grid. [0004] Also there is a trend towards providing smaller and smaller portable communication devices, especially in the range of cellular telephones, where internal space is limited. The...
