Abstract: An apparatus for processing radio frequency signals, comprising a first phase shifting stage configured to receive an RF signal and to provide n1 many, with n1>=2, phase-shifted portions of the RF signal, and at least a second phase shifting stage configured to receive the n1 many phase-shifted portions of the RF signal and to provide n2 many, with n2>=n1, phase-shifted portions of the RF signal based on the received n1 many phase-shifted portions of the RF signal, wherein a phase shift applied by the second phase shifting stage to the n1 many phase-shifted portions of the RF signal is based on at least one phase shift applied by the first phase shifting stage to the n1 many phase-shifted portions of the RF signal with respect to the RF signal.

Abstract: An antenna system including a first antenna, a second antenna and a third antenna. The antenna system includes a feed for feeding a first common signal to radiator elements of one of the second antenna or third, with a first phase difference between the radiator elements configured for a first polarization and the radiator elements being configured for a second polarization, to create a virtual polarization, wherein the virtual polarization is aligned with one of the first polarization or the second polarization in a first frequency band.

Abstract: A radome with reduced wind load is described. An example apparatus includes a radome configured to house an antenna. The radome includes a main body that extends lengthwise from a first end to a second end. The radome also includes an end cap disposed at the first end of the main body. The end cap includes a textured outer surface and corners that are rounded with respect to a vertical plane of the radome.
