Abstract (en)
[origin: WO2022174364A1] An antenna for a wireless communication device, in particular a wireless access point is disclosed. The antenna comprises at least one radiating element configured to radiate electromagnetic radiation in response to an input signal, wherein the input signal extends over an operating frequency band, a feeding network configured to feed the input signal from an input port of the feeding network to the at least one radiating element for driving the at least one radiating element with the input signal to radiate electromagnetic radiation and a narrowband band-stop filter configured to filter the input signal. The narrowband band-stop filter comprises a conducting line resonator coupled to the feeding network, wherein the conducting line resonator is configured to filter the input signal in at least one stopband of the operating frequency band and has a length that is an integer multiple of the quarter wavelength of a stopband frequency.
