Abstract

An antenna (10) for a portable radio transmitter and/or receiver includes a stripshaped supporting part (301) and a conductor pattern placed thereon. The conductor pattern includes a main conductor (300) having a constant width. In the main conductor an LC-filter (306) is connected having a resonance frequency within a high frequency band. The LC-filter acts as an interrupt within the high frequency band and gives the antenna a smaller effective length for transmitting/receiving in this band. In a lower frequency band the whole antenna is effective for transmitting/receiving. The fact that the supporting part of the antenna is made as a strip implies that the antenna when it is not in use can be folded in and for exemple placed around the housing of the portable equipment. The LC-filter has a capacitive coupling part (312) that can be placed on a piece of tape (313) including a pressure sensitive adhese. The tape piece can thereby be gradually detached for trimning the resonance frequency of the LC-filter and be completely detached to be replaced with another piece of tape having a differently designed capacitive coupling part for changing the resonance frequency.
