Abstract
This communication proposes a novel fully metallic multibeam Luneburg lens antenna that can simultaneously support the radiation of horizontal polarization (H-pol) and vertical polarization (V-pol). The proposed Luneburg lens consists of a parallel plate waveguide with varying spacing and a series of loaded metallic nails with graded heights. Seven OMTs are employed as the feeder. The measured results show that H-pol/V-pol peak gain is higher than 10.9 dBi/13.8 dBi from 28 GHz to 32 GHz. The dual-polarized beam scan loss is lower than 1.1 dB from-48° to +48°. The results show its potential for application in the MMW multibeam and multipolarization system.
