A five-layer radome panel for simultaneous use of microwave and millimeter wave bands

This paper treated the design of radome panels for combined use in the microwave and millimeter wave bands based on analysis of power transmission for three- and five-layer panels. Broadbanding of a five-layer radome panel was examined, and numerical analyses were carried out. A five-layer panel with power transmission greater than -2 dB in the 6/4 GHz and 44/20 GHz bands was successfully designed, and it was found that the bandwidth of the five-layer panel in the 44 GHz band was double that of the three-layer panel.
