Problems solved by technology

However, such users typically also desire devices that are as small as possible, and reduced device size can reduce antenna placement efficiency and / or bandwidth in multiple operating frequency bands
[0003] For example, due to size constraints on the device, the printed wiring board of the device may have a natural resonant mode different from that of the antenna, which may reduce efficiency and / or bandwidth

Embodiment Construction

[0033] In the following description, the words "connected" and "coupled" and their derivatives mean operatively connected or coupled. It should be understood that any number or combination of intermediate components may be present (including no intermediate components). Furthermore, it should be understood that a connection or coupling may be a physical galvanic connection and / or an electromagnetic connection.

[0034] figure 2 and 3 Apparatus 18 is shown comprising: conductive element 30 configured to receive antenna 32 and form non-conductive region 52 between conductive element 30 and base element 22; and switch 34 having a first A closed configuration and a second open configuration, the first closed configuration is configured to couple the conductive element 30 to the base element 22 across the non-conductive region 52 and provide a first current path 56 having a first electrical length and a first resonant frequency, the second The open configuration is configured t...

Abstract

An apparatus comprising: a conductive member configured to receive an antenna and to form a non-conductive region between the conductive member and a ground member; and a switch having a first closed configuration and a second open configuration, the first closed configuration being configured to couple the conductive member to the ground member across the non-conductive region and to provide a first current path having a first electrical length and a first resonant frequency, the second open configuration being configured to provide a second current path having a second electrical length and a second resonant frequency, the second resonant frequency being lower than the first resonant frequency.

Description

technical field [0001] Embodiments of the invention relate to apparatus for wireless communication. In particular, the embodiments relate to means for wireless communication in a portable communication device. Background technique [0002] Apparatus such as portable communication devices typically include an antenna arrangement for enabling the apparatus to communicate wirelessly. Users of such devices may require the ability to communicate in multiple operating frequency bands. For example, in the United States, the Global System for Mobile communications (US-GSM) has a frequency band of 824-894 MHz, while in Europe, the Global System for Mobile communications (EGSM) has a frequency band of 880-960 MHz. However, such users typically also desire devices that are as small as possible, and a reduction in device size may reduce antenna arrangement efficiency and / or bandwidth in multiple operating frequency bands. [0003] For example, due to size constraints on the device, t...
