The system comprises: a light mounted to an exterior of a vehicle; an external network comprising an external wireless access point comprising a first antenna positioned on the exterior of the vehicle at the location of the light, the external network configured to automatically connect to an off-board server, the off-board server located outside the vehicle; an internal network comprising internal wireless access point comprising a second antenna, the second antenna positioned on the interior of the vehicle at the location of the light, the internal network configured to automatically connect to an on-board server, the on-board server internal to the vehicle; and a circuit coupled to the external access point and to the internal access point, the circuit configured to transfer data bi-directionally between the off-board server and the on-board server.

A radome having localized areas of reduced radio signal attenuation includes a body having a first portion and a second portion. The first portion has a reduced radio signal attenuation property in a transmit band and a second portion has a reduced radio signal attenuation property in a reception band.

An antenna assembly includes a circularly polarized antenna housing configured to mount to a mounting surface. The antenna assembly also includes a vertical antenna housing having a first end proximate to the circularly polarized antenna housing, as well as a distal end extending normally from the circularly polarized antenna housing.

An antenna includes an antenna substrate comprising a first end and a second end, and an antenna element attached to the antenna substrate. The antenna element is configured to receive communication signals within a partial hemispherical-shaped signal reception region oriented about the first end of the antenna substrate. A signal gain reduction portion is at least partially located between the antenna element and the second end of the antenna substrate, and is configured to reduce signal gain in an opposite partial hemispherical-shaped region oriented about the second end of the antenna substrate.

A mechanically steered, horizontally polarized, directional antennae for aerial vehicles, such as UAVs. The antenna system can include a planar substrate with a horizontally polarized antenna embedded therein. A rotation member, on one end, can be attached to the planar substrate, and can extend from an external surface of the aerial vehicle. An actuator can be coupled to the rotation member to rotate the rotation member. A communication controller of the aerial vehicle can control the actuator to beam horizontally polarized radiofrequency (RF) waves to a target receiver or receive a wave front from a target transmitter.

A radome assembly (20) includes a frame (30) conforming in contour with an aircraft fuselage (14) for being fixedly mounted thereto. A radome (32) having an aerodynamically streamlined elongate contour including a central bulb (34) is spaced from the frame (30) to house an antenna (26) therein, the radome (32) being tuned in configuration to define an unobstructed radio-frequency (RF) window (28) diverging outwardly from atop the frame (30). The radome (32) is pivotally mounted atop the frame (30) by a hinge (36,74,78) hidden inside the frame (30) below the RF window (28) when the radome (32) is stowed closed atop the frame (30) and antenna (26).

An AESA antenna configuration for simultaneous transmission and receiving of communication signal includes: a housing having eight sides; four transmit sides and four receive sides alternating there between and forming a 45 degree angle with their respective neighbor sides, where cross sections of the housing in a plane perpendicular to a vertical axis of the housing are tapered from a top to a bottom of the housing in the vertical direction by a cant angle.

The present invention discloses an antenna and an unmanned aerial vehicle, where the antenna is applied to the unmanned aerial vehicle and the unmanned aerial vehicle includes a camera apparatus, the antenna including an antenna body and a bending part connected to the antenna body; and the bending part bends to a direction avoiding a field of view of the camera apparatus. Based on the foregoing technical solutions, in the embodiments of the present invention, it can be ensured that the antenna has a certain effective length to obtain a relatively strong radio signal, and avoids a shooting vision of the camera apparatus at the same time, so that images satisfying user demands are obtained.
