The present disclosure relates to the field of television receiving antennas, and discloses an outdoor antenna, comprising a main body and a pair of reflective nets, wherein the reflective net comprises an assembly body, the main body comprises a fixing base, the assembly body and the fixing base are plugged into each other, and the assembly body and the fixing base are connected by a snap-connection, which allows the assembly body and the fixing base to be tightly combined with each other after being plugged in. The reflective nets can be detached from the main body, so that the entire outdoor antenna can be disassembled, which avoids packaging of the entire outdoor antenna and reduces the packaging volume. Furthermore, through the snap-connection, the assembly body and the fixing seat will not be loosened after being plugged in, and can be tightly combined with each other.

Deployable reflector system includes a boom which is extended from a rigid base. A reflector support structure is secured to a carrier end of the boom opposed from the base. The reflector support structure is configured to transition from a collapsed configuration to an expanded configuration. A tension element coupled at one end to the reflector support structure extends along a length of the boom to the base. The tension element is tensioned as a result of extending the boom, whereby a tension force is provided. The reflector support structure is transitioned from the collapsed configuration to the expanded configuration responsive to the tension force, whereby the same actuator mechanism that extends the boom also expands the reflector support structure.

An antenna assembly has a solar layer having one or more solar cells generating solar power, an antenna layer connected to the solar layer and having electronic components utilizing the solar power generated by the solar layer, and a thermal dissipation device dissipating heat locally at the antenna assembly. A large number of antenna assemblies are connected to form an antenna array in which heat is generated locally at each antenna assembly and dissipated locally at each antenna assembly.

Exemplary embodiments are described herein for compactable antennas. Exemplary compactable antennas include a support structure and a reflector surface. The support structure may directly or indirectly define the reflector shape. Exemplary embodiments comprise deployable support structures to permit the compactable antenna to have a smaller volume stowed configuration and a larger volume deployed configuration.

A flexible plate-based radar antenna device with a field of view over 160 degrees comprises a support base, two antenna boards, and a circuit board. The support base has an installation surface and two inclined surfaces. Two antenna boards are flexible plates, and their back surfaces are respectively stuck onto two inclined surfaces of the support base. Several set of antennas are disposed on front surface of the antenna boards for transmitting detection signals and receiving reflection signals from at least one obstacle. The circuit board is electrically connected with two antenna boards, controlling the antenna boards to transmit and receive signals. As long as the shape of the support base is adjusted to make the antenna boards able to stick onto it, the antenna boards of the present invention are applicable to radar devices having an arbitrary shape. Therefore, the present invention can simplify the fabrication process.
