“…This means that any transmitter or receiver has a certain amount (at least one) of transmit or receive antennas depending on the antenna type and design. Suitable antenna types include, but are not limited to, horn antenna [64], [65], [68], [74], [102], [109], [116]- [119], [142]- [155], yagi antenna [149], lens antenna [59], [105], reflectarray antenna [85], [86], cassegrain antenna [88], [113], (on-chip integrated) patch antenna [49], [54], [82], [127], [128], [139], [151], [156], [157], and parabolic antenna [110], [112]. Suitable antenna designs include, but are not limited to, phased array antenna design [144], [145], [147], [158]- [162], frequency scanned antenna design [87], fan and pencil beam antenna design [119], gaussian beam antenna design [100], and omni-directional antenna design [146].…”
