Abstract

This study proposes a systematic optimisation process of array configurations for controlled reception pattern antenna arrays. The array consists of a single reference antenna at the centre and four auxiliary antennas at the outer perimeter and is mounted on an anisotropic ground platform with an inter-element spacing of about 0.3λ. Only the mounting angles are adjusted to find the optimum array configuration. The proposed process is evaluated by comparing its performance with the global optimum, a conventional array configuration and random array configurations. The results demonstrate that the proposed process achieves a radiation gain close to the global optimum, and no significant gain reductions are found in the auxiliary antennas.
