摘要： According to an example embodiment, an antenna assembly (110) for a radar apparatus (100) is provided, the antenna assembly comprising: a first feed antenna (111a) arranged to transmit outbound radio waves of a transmitter beam (113a) based on a transmitted RF signal supplied thereto and a second feed antenna (111b) arranged to capture a received RF signal based on inbound radio waves of a receiver beam (113b) received thereat; and a lens element (112) arranged to collimate the transmitter beam (113a) obtained via a back end of the lens element (112) for transmission from a front end of the lens element (112) to a monitoring direction and to focus the receiver beam (113b) received at the front end of the lens element (112) from the monitoring direction for reception via the back end of the lens element (112) at the second feed antenna (111b), wherein the first and second feed antennas (111a, 111b) are disposed on a conductive ground plane (115) that is offset from the back end of the lens element (112) by a predefined distance (k) in direction of a center axis (A) of the lens element (112), and wherein a volume between the back end of the lens element (112) and the ground plane (115) comprises material that has a refractive index that is smaller than that of the lens element (112) for converging the outbound and inbound RF beams between the back end of the lens element (112) and the first and second feed antennas (111a, 111b).

摘要： The present application provides an antenna structure and a radio device. The antenna structure comprises a first antenna and at least one second antenna. Said first antenna comprises a reflector and a feeder located at the focal point of said reflector. The main body structure of said reflector is a non-metal structure and is plated with a metal layer on its inner surface. Each second antenna is carried on said main body structure and co-sharing formed with said main body structure. According to the scheme of the present application, since the main body structure of the first antenna in the antenna structure adopts a non-metal structure with each second antenna being carried on said main body structure and co-sharing formed with said main body structure, co-sharing form between any of the antennas can be achieved with this antenna structure. Furthermore, this antenna structure is easy to manufacture, causes minimal interference to the reflector antenna, and is applicable to any radio device.

摘要： The current invention is a wideband multi-element frequency-selective-surface sub-reflector (100) with application to a single offset antenna. The wideband multi-element frequency-selective-surface sub-reflector (100) includes a circuit board (10), a first outer cover (20) and a second outer cover (30). The circuit board (10) includes an insulating layer (12), a first metal layer (14) and a second metal layer (16). The first metal layer (14) and the second metal layer (16) are placed on the two sides of the insulating layer (12), include respectively a plurality of double coupling hollow aperture elements (142, 162), and are used as two reflecting interface end-planes to form a resonant cavity. The first outer cover (20) and the second outer cover (30) are respectively arranged on surfaces of the first metal layer (14) and the second metal layer (16). The wideband multi-element frequency-selective-surface sub-reflector (100) reflects low frequency signals, and then a low frequency receiver (300) receives the reflected low frequency signals. High frequency signals penetrate the double coupling hollow aperture elements (142, 162) of the wideband multi-element frequency-selective-surface sub-reflector (100), enabling designed target signals to couple from an incoming side to a transmission side to achieve a feature of a high penetrability.
