Potential Uses of a New Type of Antenna in Aviation

摘要

The article is dealing with the theory of Crossed Field Antenna-CFA. This type was patented recently and sees its practical application particularly in area of long and medium waves. A brief theoretical analysis of the principle of radiation of this new type of antenna, which is not wave dependent to its physical dimensions, is present in this article. The independence on waves of the current CFA s enables substantial reduction of mechanical dimensions for medium wave (MW) antennas. Thereby, the dimensions of MW antennas reduces from hundreds of meters to structures measuring only several meters without affecting their electrical parameters-like power, impedance and radiation. The article is presenting a proposal and an analysis regarding the potentials in using CFA in high frequency (HF) and very high frequency (VHF) frequency bands. From this point of view, reducing the size of the airborne communication antennas is among the long-term goals of the authors research conducted at the educational institute.
