The receiving and transmitting devices described herein include so-called magnetic or loop antennas. Although loop antennas, such as those described above, have a directivity. But in the prevailing installation situations in the field of door and gate technology and home automation, the positioning of the antenna is not primarily from the point of view of directivity. Rather, good results are sought in as many installation situations as possible. Especially with handheld transmitters, the positioning of the antenna is not really predictable. The directivity of the antenna therefore plays only a minor role in the present embodiments.

The loop antenna can be formed by a conductor track (copper, gold-plated copper, etc.) or by a bow-shaped sheet metal element. Air is preferred over board material as a dielectric. However, aerials with air as a dielectric usually require more space, so depending on the application of this insignificant Disadvantage can be accepted to make the transmitting and receiving devices each more compact. To further improve the board material can be milled out to increase the proportion of air at the dielectric.

• • Die Loop-Antenne kann wie ein gewöhnliches Bauteil automatisch bestückt werden.
• • Es besteht eine geringere Gefahr von Montagefehlern bei der Endmontage.
• • Es ist keine nachträgliche Ausrichtung und/oder Justage erforderlich.
• • Das Antennenmaterial ist preiswertes, gestanztes Blech.
• • Das Dielektrikum enthält überwiegend Luft statt Platinenmaterial FR4, wodurch der Verlustfaktor (Tangens des Verlustwinkels) verringert werden kann.
• • Durch Inkaufnahme eines etwas erhöhten Verlustfaktors lässt sich die Antenne und die zugehörige Sende- oder Empfangseinrichtung weiter verkleinern.
• • Für die Anpassung an unterschiedliche Trägerfrequenzen reicht die Änderung eines Bauteils, beispielsweise eines frequenzbestimmenden Kondensators, aus.

Compared to a wire antenna, a loop antenna has the following advantages, among others:

• • The loop antenna can be automatically populated like a normal component.
• • There is less risk of assembly errors during final assembly.
• • No subsequent alignment and / or adjustment is required.
• • The antenna material is inexpensive, stamped sheet metal.
• • The dielectric mainly contains air instead of FR4 board material, which can reduce the loss factor (loss tangent tangent).
• • By accepting a slightly higher loss factor, the antenna and the associated transmitting or receiving device can be further reduced.
• • For adaptation to different carrier frequencies, the change of a component, for example a frequency-determining capacitor, is sufficient.
