Abstract
This paper discusses the design of an economical wideband array suitable for low-frequency radio astronomy applications. The array consists of 32 non-uniformly spaced, uniformly excited, log periodic antennae designed to operate over a 2 : 1 frequency band. At the highest operating frequency, the array has a beam-width of approximately 1° and side-lobes at least 16–5 dB below the main beam level. The theoretical limit to which the'side-lobes of an idealized array, having the same gain and length, can be suppressed is 17 dB.
