摘要： The present invention relates to a portable communication device, an antenna arrangement and a case for a portable communication device. The portable communication device comprises a casing including a first in-built driven antenna element (26) extending a length along a longest side of the casing. Either the portable communication device or the case includes at least one passive beam directive element (32) distanced from and generally extending along at least most of the same length as the first in-built driven antenna element. Because of this electromagnetic radiation generated by the first in-built driven antenna element is enhanced in a direction away from a side (18) of the casing intended to be facing a user.

摘要： A tuning arrangement in a radio receiver includes a front-end circuit having a tunable band-pass filter that is capable of tunably selecting channels within at least one frequency band of an RF signal. A noise source coupled to an input of the tunable band-pass filter introduces a wide-band noise signal into the front-end circuit. A signal detector coupled to an output of the front-end circuit measures at least one signal power associated with a filtered noise signal derived from the wide-band noise signal. A tuning controller, coupled to the tunable band-pass filter by a tuning control signal, adjusts the tuning control signal in response to the at least one measured signal power for tuning the tunable band-pass filter to a desired filter response.
