Giselle: A Mutually Orthogonal Triple Twin-loop Ground-symmetrical Broadband Receiving Antenna for the HF Band

Abstract

This report describes development of a tri-axial mutually orthogonal broadband twin-loop receiving antenna for the HF band. The three twin-loops have been arranged so that they exhibit the same distributed parameters between themselves and ground. The upper frequency limit of the antenna is discussed and a method for extending the low frequency cut-off is presented. The antenna noise factor is calculated from measured data.
