ANTENNAS

摘要

This invention relates to a radiating element (20) for use in array antennas. The radiating element (20) is of simplified design and comprises a front region (26) and a rearward region (28) that are preferably substantially rectangular, which permit higher frequency limits than more conventional Vivaldi elements while maintaining the lower frequency limit. Additionally, by deployment of an array of a plurality of such elements (20) such that no gaps are formed between adjacent elements (20) along the array antenna, very wide bandwidth can be obtained using the array.
