Lorentz Violation in Torsional Antenna Fabio Cardone1,2 · Gianni Albertini3 · Domenico Bassani4 Accepted: 2 October 2020 © The Author(s) 2020
Abstract A torsional-antenna and a log-periodic antenna are used as a source and an analyzer, respectively, to investigate the possible anomalies of an electro-magnetic field. An unexpected isotropic signal has been detected using those torsion angles, which correspond to a breakdown of the Local Lorentz Invariance, which was found in the past. This coincidence is interpreted as the recovery of a lost symmetry by torqueing the antenna, thus putting in evidence that this Lorentz violation is of angular nature. Introducing a new physical dimension—not only a mathematical dimension as a way to rearrange some equations—is here proposed as a general rule to recover the lost symmetry.

1 Introduction In recent years, a patent was accepted (Patent 2014) concerning a bipolar antenna having two loops torqued by a fixed angle. This antenna has a very large band of emission and a good efficiency in transmission. They are higher than in the not torqued case, thus making it particularly suitable in radio communications by satellite in asynchronous orbits. In order to investigate the effects of the torsion angle, a systematic study was performed (Paci 2018). In particular, the reflected signal of a transmission antenna as a function of the torque angle was investigated, the not torqued case corresponding to a so-called “crossloop antenna”.

In the following, we present and discuss the results obtained when a log-periodic antenna is used to study the emission of this torqued antenna. These measurements have been performed in an anechoic edge, in order to reduce the external noise. Examples of antennas based on torsion around an axis are the Helica Filar boards (QHF) (Kilgus 1975), suitable for receiving the transmissions of the NOAA sat polar satellites and WX sat on the frequency of 137 MHz. These antennas were designed at NASA and are used in any area where a good sensitivity and an appropriate directionality are pursued. They consist of square loops twisted in a spiraling shape to form an apparent torsion angle of 180°; the presence of a balun and their stiffness make them different from the one we are considering and not so simple to put in evidence the effects of twisting the two loops. More recently, the influence of surface twists on the characteristics of an antenna, to be placed on the nacelle of mil
