Embodiment Construction

[0014] figure 1 Schematically shown is a device 2 which automatically decouples electrically conductive components 12 at RF frequencies.

[0015] The apparatus 2 may be incorporated into a module of the wireless device 100, or may be incorporated into the wireless terminal 100, such as, for example, Figure 5 Shown in the mobile cellular phone handset.

[0016] The device 2 comprises: an antenna 4 and a plurality of circuits 10 arranged in an array 11 .

[0017] The antenna 4 may be, for example, a monopole antenna or an inverted-F antenna, such as a planar inverted-F antenna (PIFA).

[0018] The antenna 4 has one or more operating frequency ranges. Each frequency range or band has lower frequencies and higher frequencies. One (or more) operating resonant frequency ranges may correspond to one (or more) cellular communication frequency bands, such as: US-GSM850 (824-894MHz), EGSM 900 (880-960MHz), PCN / DCS 1800 (1710- 1880MHz), US-WCDMA 1900 (1850-1990) frequency band, WCD...

Abstract

An apparatus comprising an antenna having operational frequencies, and an electrical circuit comprising a first electrical component adjacent the antenna and a second component for decoupling said electrical circuit from the antenna at the operational frequencies of the antenna.

Description

technical field [0001] Embodiments of the invention relate to positioning a conductive component near an antenna. Background technique [0002] Antennas are sensitive to the presence of conductive components in the vicinity, especially grounded components. [0003] Therefore, it is difficult to optimize the positioning of conductive components without significantly compromising antenna performance, since there may be "keep-out" zones near the antenna where conductive components cannot be placed. [0004] It is desirable to locate conductive components near the antenna without significantly compromising antenna performance. Contents of the invention [0005] According to one embodiment of the present invention, there is provided an apparatus comprising: an antenna having an operating frequency; and a circuit comprising a first electronic component in the vicinity of the antenna, and for connecting the circuit at the operating frequency of the antenna to A second component...
