ANTENNA Russian patent published in 2002 - IPC

FIELD: antenna engineering; broadband radio communication systems including duplex ones. SUBSTANCE: antenna has radiator mounted through insulator on conducting shield. Internal conductor of feeder is connected through inductive load to radiator lead and external one, to conducting shield. Radiator is made in the form of conductor whose length is sufficient to pass one current minimum, Load of parallel-connected inductance coil and capacitor is inserted in series with radiator in the region of current minimum at higher operating frequency. EFFECT: enlarged operating frequency range or ability of multiple-frequency operation for independent setting of operating frequencies. 5 dwg
