Zusammenfassung: | This invention relates to antennas. More particularly, this invention relates to a filtered antenna. Specifically, this invention relates to an antenna for marine band applications that filters out undesirable frequencies adjacent to the marine band.
An antenna () for minimizing reception of undesirable signals below a predetermined frequency band includes a first and a second terminal (A, A′) connectable to at least a receiver (). The antenna components are connected to the first and second terminals, and a filter () is integrally connected across the first and second terminals (A, A′). The filter matches an impedance value of the antenna components with an impedance value of the receiver. Moreover, the filter effectively forms a short circuit at the undesirable frequency to minimize reception of undesirable signals below the predetermined frequency band. |
