Problems solved by technology

However, from a physical point of view, this is incorrect because the operating temperature of the loop remains the same regardless of the shortening
The result is that the signal-to-noise ratio (S / N) is worsened due to the lower Q-factor (i.e., lower resonance rise), the use signal is weakened

Abstract

Embodiments of the present invention relate to a subscriber of a wireless communication system, wherein the subscriber comprises a transmitting and / or receiving device and an antenna arrangement connected to the transmitting and / or receiving device, wherein the antenna arrangement comprises a magnetic antenna having a loop that is interrupted once or multiple times.

Description

technical field [0001] Embodiments of the invention relate to participants of a communication system, and in particular to participants with magnetic antennas. Other embodiments relate to terminal points and base stations with magnetic antennas. Some embodiments relate to the implementation of magnetic loops. Background technique [0002] Often electric antennas or short antennas are used, especially in the field of sensor nodes. For example, when using a current conventional electric antenna at 868 MHz, a length of about 15 cm is required as a 1 / 2 lambda (1 / 2 lambda) radiator. When using a shorter antenna, the gain of the antenna is reduced. Furthermore, due to the fact that the antennas used are detuned in the proximity of conductive or dielectric active elements, the processing capabilities of devices with antennas are limited and their gain is thus further reduced. In addition, with an electric antenna, transmission cannot be performed outside a shielded environment ...
