摘要: A multiple beam array antenna system comprises a plurality of radiating elements (82) provided from stripline-fed open-ended waveguide coupled to a Butler matrix beam forming network (86). The Butler matrix beam forming network is coupled to a switched beam combining circuit (90). The antenna can be fabricated as a single Low Temperature Co-fired Ceramic (LTCC) circuit.
