Abstract

Es wird eine miniaturisierte Antenne mit mindestens einem keramischen Substrat (10) und einer Metallisierung insbesondere zur Anwendung im Hochfrequenz- und Mikrowellenbereich beschrieben. Die Antenne zeichnet sich dadurch aus, dass die Metallisierung eine Oberflächenmetallisierung ist, die durch eine Zuführung (12) für abzustrahlende elektromagnetische Energie, mindestens eine erste Metallisierungsstruktur (30), sowie eine entlang zumindest eines Teils des Umfangs des Substrates (10) verlaufende Leiterbahn (20) gebildet ist, die die Zuführung mit der mindestens einen ersten Metallisierungsstruktur (30) verbindet, wobei die erste Metallisierungsstruktur (30) einen ersten, sich von einer der Zuführung (12) gegenüberliegenden Seite des Substrates in Richtung auf die Zuführung erstreckenden Leiterbahnabschnitt (31) sowie ein erstes Metallisierungsplättchen (32) umfasst. Die Antenne kann durch Oberflächenmontage auf eine Schaltungsplatine aufgebracht werden und weist eine große Impedanz- und Strahlungsbandbreite auf, so dass sie insbesondere zur Anwendung für Mobiltelefone im GSM- und UMTS-Bereich geeignet ist.

Figure 00000001
A miniaturized antenna with at least one ceramic substrate (10) and a metallization, in particular for use in the high frequency and microwave range, is described. The antenna is characterized in that the metallization is a surface metallization, which is provided by a feed (12) for electromagnetic energy to be emitted, at least one first metallization structure (30), and a conductor track (at least part of the circumference of the substrate (10)) 20) which connects the feed to the at least one first metallization structure (30), the first metallization structure (30) having a first conductor track section (31) extending from a side of the substrate opposite the feed (12) in the direction of the feed ) and a first metallization plate (32). The antenna can be applied to a circuit board by surface mounting and has a large impedance and radiation bandwidth, so that it is particularly suitable for use in mobile telephones in the GSM and UMTS range.
