Computer aided design of a high performance slotted waveguide array antenna for maritime patrol radar applications

The present paper deals with the design and development of an horizontally polarised, lightweight, high-performance slotted waveguide array antenna in X-band for maritime patrol radar applications. A design methodology making use of extensive electromagnetic modelling where all the radiating and coupling slots are characterised using the method of moments and feed networks using FEM have been used. The construction method uses a standard bonding technique and fixing systems to lower costs and realise mass production instead of the complicated dipbrazing process
