Abstract
A periodic array for use as an electromagnetic energy resonant array or reflector having a high density pattern formed from individual chevron shaped elements. Various interlocked and interlaced patterns of elements provide the array designer with more flexibility in controlling bandwidth and stabilizing the functional relationship between frequency and the angle incidence with the electromagnetic energy. Furthermore, structural patterns of chevron shaped elements readily incorporate structural paths for lightning conduction and mechanical support without severely altering the electrical performance.
Claims4
A metallic radome, comprising:
- a. a curved surface of thin metallic material;
- b. a plurality of chevron-shaped slots in said curved surface;
- c. said chevron-shaped slots being formed of two linear slot elements connected end-to-end at an angle of substantially 90.degree.;
- d. said chevron-shaped slots being uniformly distributed on said curved surface in a closely spaced pattern with adjacent linear slot elements parallel to each other.
