This paper describes a simple methodology to obtain an Ultra-Wide Band characteristic with dual polarization and high radiation performance of a miniaturized compact array antenna for Multi-Mission C band Radars applications. The proposed array antenna is composed of a principal T-junction power divider and 32 circular radiating elements. It is manufactured on 1.58 mm thick FR 4 epoxy with miniaturized dimensions (110 mm x 214 mm x 1.58 mm). Design objective adopted in this work is to explore the Ultra-Wide Band characteristic and high radiation pattern performance consisting of high co-polarization at resonance frequencies and low cross-polarization for a miniaturized antenna structure that covers the entire C band. The intended design of the optimal proposed structure has been obtained after processing through many steps, starting from the basic antenna and its optimization to the final proposed array antenna structure. All the simulation investigations have been carried out using numerical methods and verified with measurement. The suggested array antenna is well miniaturized and it has good characteristics in terms of bandwidth (122 %), gain (15-24 dB), side lobes level and co-cross polarizations which are required in the majority of radars processing area. |
