Abstract
Spectral coding is of special interest in high-sensing-capacity imaging applications. This letter presents the design, fabrication, and experimental validation of a lightweight and robust 3-D-printed compressive horn antenna, capable of performing spectral coding for such applications. First, a pyramidal horn antenna is designed to operate within the E-band. Then, a dielectric piece with a pseudorandom geometric pattern is inserted inside the horn to distort the radiation pattern of the antenna in both near- and far-field regions. The performance of both antennas is evaluated by their return loss and radiation patterns.Keywords
