    摘要: A phased array antenna includes multiple antenna elements where each antenna element is an antenna apparatus that includes an antenna integrated with a filter. Each antenna apparatus includes a plurality of resonators where at least some of the resonators are each enclosed in a metal cavity and at least one resonator is exposed to free space to form a radiator element. Each antenna apparatus has a filter transfer function that is at least partially determined by dimensions of the radiator element and the position of the radiator element within the antenna apparatus. The scan volume of the phased array antenna is dependent on at least one physical dimension of the filter of the antenna apparatus.
