Dual-polarized corporate-feed plate-laminated waveguide slot array antenna for 60 GHz-band

The dual-polarized corporate-feed waveguide slot array antenna is designed for the 60 GHz band. Using the multi-layer structure, we have realized dual-polarization operation. Even though the gain is approximately 1 dB lower than the antenna for the single polarization due to the -15dB cross-polarization level in 8=58°, this antenna still shows very high gain over 32 dBi over the broad bandwidth. This antenna will be fabricated and measured in future.
