摘要: A wideband high-gain high-efficiency hybrid integrated plate array antenna for inter-satellite links is presented in this paper. This consists of microstrip patches, substrate waveguide (SIW) and power dividers. novel feeding structure proposed to excite the sub-array with a characteristic. The radiation efficiency SIW arrays different sizes compared by experiment. SIW-waveguide topology optimized realize high efficiency, low cost compact configuration at same time. fabricated through standard multi-layer PCB process milling technology. Measured results demonstrate about 14.6% reflection coefficient bandwidth ( $\vert {\rm S}_{11}\vert dB) frequency band 57–66 GHz. gain fluctuates less than 3 dB within band. 1 8.1% 59–64 maximum 39.2 dBi 59 GHz 41%.
