Abstract : This report describes a directional loop array antenna for very low frequency (VLF) reception. The array comprises four closely spaced loop antennas forming a unidirectional reception pattern with a main beam of less than 43 deg between half power points. The array combines two double loop coaxial antennas dispersed with their axis parallel along 45 deg lines. The signal from one double loop array is delayed sufficiently such that a unidirectional reception pattern is formed.
