Omnidirectional Antenna with Complex Conjugate Impedance for Radio Meteor Detection

Abstract

In the field of meteor study using radio techniques, the transmitting antenna of the radio beacons is most of the time a classical turnstile antenna design. As an alternative, it is proposed a pyramidal shaped omnidirectional antenna with complex conjugate impedance, which exhibits similar performance. By design, this type of antenna does not require additional electrical components for obtaining the circular polarization and the impedance matching. Furthermore, the pyramidal shape allows the practical implementation of the antenna using a simple and light mechanical structure.
