Abstract
Kleine magnetische Funkantenne für Frequenzen im Bereich 27 MHz zum Funksendebetrieb an Objekten und Fahrzeugen, dadurch gekennzeichnet, dass ein Ferritstab (2) mit einer Antennenwicklung (4) isoliert auf einem Montageblech (6) angebracht ist und mit einem Kondensator (3) einen Serienschwingkreis bildet.Small magnetic radio antenna for frequencies in the range 27 MHz for radio transmission on objects and vehicles, characterized in that a ferrite rod (2) with an antenna winding (4) isolated on a mounting plate (6) is mounted and with a capacitor (3) forms a series resonant circuit ,
Description
Mobile Funkantennen für Funksende- und Empfangsanlagen im 27 MHz Frequenzbereich zum Betrieb an Fahrzeugen, sind üblicherweise als Rundstrahlantennen ausgeführt.mobile Radio antennas for Radio transmission and reception systems in the 27 MHz frequency range for operation on vehicles, are common designed as omnidirectional antennas.
Damit wird bewusst eine annähernd kreisrunde Abstrahlung bewirktIn order to becomes aware of an approximate circular radiation causes
Die „Magnetische Funkantenne für 27 MHz” soll an der Rückseite eines Fahrzeuges, einer mobilen Warnanlage oder eines Warnleitanhängers z. B. bei der Straßenbauverwaltung montiert werden.The Magnetic Radio antenna for 27 MHz "should at the back a vehicle, a mobile warning system or a Warnleitanhängers z. B. in the road administration to be assembled.
Um Funkwarnsendungen von einem CB Funkwarnsender zielgerichtet von diesen Objekten abzustrahlen, muss die Funkantenne eine bestimmte Strahlungscharakteristik haben.Around Radio alarm transmissions from a CB radio alarm transmitter targeted by To radiate these objects, the radio antenna has a certain radiation characteristics to have.
Diese Strahlungscharakteristik soll vorzugsweise in Längsrichtung der Fahrzeugachse, auf der die Antenne befestigt ist strahlen, um den Nebenverkehr möglichst wenig zu beeinflussen.These Radiation characteristic should preferably in the longitudinal direction of the vehicle axle, on which the antenna is fixed radiate to the side traffic preferably little to influence.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, dass normale Antennen eine annähernd rundstrahlende Abstrahlcharakteristik aufweisen.Of the in claim 1 protection invention is based on the problem normal antennas are approximate have omnidirectional radiation.
Dieses Problem wird mit der „Magnetischen Funkantenne für 27 MHz” gelöst.This Problem becomes with the "magnetic radio antenna for 27 MHz "solved.
Mit der Erfindung wird erreicht, dass die Antenne eine Abstrahlcharakteristik erhält die überwiegend nach vorn und hinten abstrahlt.With The invention is achieved in that the antenna has a radiation characteristic receives the predominantly radiates forward and backward.
Die seitliche Abstrahlung wird dabei deutlich unterdrückt.The lateral radiation is clearly suppressed.
Da die Antenne sehr klein ausgeführt ist, kann diese an Fahrzeugen und Objekten aller Art befestigt werden.There the antenna is very small is, this can be attached to vehicles and objects of all kinds.
Dies wird durch die Anordnung der Spule auf einem Ferritstab erreicht.This is achieved by the arrangement of the coil on a ferrite rod.
