  • Slot chevron element for periodic antennas and radomes
    Patent number: 4287520
    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.
