Abstract: A front end of a radar system is provided with a first front end apparatus and a second front end apparatus. A first transmit planar component and a first receive planar component in the first front end apparatus are arranged to be perpendicular to one another. A second transmit planar component and a second receive planar component in the second front end apparatus are arranged to be perpendicular to one another. A linear array of antennas is located along a second end of each planar component. Polarization of a first set of waves transmitted from the linear array of antennas of the first transmit planar component and polarization of a second set of waves transmitted from the linear array of antennas of the second transmit planar component are perpendicular to one another.

Abstract: A radar system includes a transmit front end device including a transmit planar component, and a receive front end device including a receive planar component. Each of the transmit planar component and the receive planar component includes a first end, a second end, a cavity space and a linear array of antennas. The cavity space is bounded by beam ports along a first side of the cavity space and by array ports along a second side of the cavity space. The cavity space is in operative communication with the beam ports and with the array ports to form a Rotman lens. A linear array of antennas is located along the second end of the planar component. The transmit planar component and receive planar component are arranged such that the linear array of antennas of the transmit planar component and the linear array of antennas are perpendicular to one another.

Abstract: A base station for a communication network comprising at least one transmit planar component and at least one receive planar component is provided. Each of the planar components includes a first end, a second end located opposite the first end, a cavity space and an M number of antennas. The cavity space is bounded by a B number of beam ports along a first side of the cavity space and by an M number of array ports along a second side of the cavity space. The cavity space is in operative communication with the beam ports and with the array ports to form a Rotman lens. The M number of antennas are arranged in an array and are located along the second end of the planar component. Each of the antennas is in operative communication with a corresponding one of the array ports.
