摘要: A low-altitude frequency domain electromagnetic detection device and an electromagnetic detection method are disclosed. A transmitting wireframe, a receiving wireframe I, a transmitting and receiving system and a receiving wireframe II of the detection device are connected with supporting rods at intervals, and the supporting rods are connected with an unmanned aerial vehicle. A sine wave generation module of the transmitting and receiving system is connected with the transmitting wireframe, the receiving wireframes I and II are connected with a dual-channel synchronous data acquisition module, and the dual-channel synchronous data acquisition module is connected with a main control module. The main control module controls the sine wave generation module, receives data of an altimeter, a GNSS module and the dual-channel synchronous data acquisition module and records the data in a storage module. The electromagnetic detection method comprises equipment assembly, coefficient calibration, data acquisition and normalized secondary field calculation.

摘要: An antenna apparatus is provided that allows cooling with a high heat dissipation effect even when the antenna apparatus is reduced in height. The antenna apparatus includes an antenna element, a mount on which the antenna element is provided, a radome to accommodate the antenna element, and a skirt provided on the mount. The mount on which the antenna element is provided has a side surface including a surface to which an inner circumferential surface of the radome is attached. A skirt provided on the mount has an outer circumferential surface on which a heat dissipation fin to dissipate heat to outside is formed. The heat is transmitted from the antenna element through the mount to the skirt.

摘要: A dual feed slot-based circularly polarized wideband ultra high frequency (UHF) antenna for a cubic shaped satellite (Cube-Sat) is described. The UHF antenna includes a circuit board, a metallic layer, a hexagonal meandered slot, a capacitor, a first feed horn, and a second feed horn. The circuit board has a front side and a back side separated by a dielectric material. The metallic layer covers the back side of the circuit board. The hexagonal meandered slot symmetrically includes six legs of equal length and six vertexes. The capacitor is switchably connected to the metallic layer. The first feed horn is connected by a first feed line to a first edge of the front side of the circuit board. The second feed horn is connected by a second feed line to a second edge of the front side of the circuit board.

摘要: Systems, apparatuses and methods may provide for an antenna system including a cavity and a broadband antenna coupled to the cavity. The broadband antenna may include surfaces defining a slot, wherein a cross-section of the cavity defines a resonant frequency range of the slot. The broadband antenna may also include a plurality of transmission lines, wherein the plurality of transmission lines bridge the slot and are spaced apart at a sub-wavelength distance with respect to a target frequency range of the antenna system. Additionally, the broadband antenna may include a plurality of inductive tuning elements, each inductive tuning element being disposed adjacent to one of the plurality of transmission lines, wherein the target frequency range is a function of the resonant frequency range and an impedance associated with the plurality of inductive tuning elements.

摘要: A space antenna may include an extendible boom movable between stored and deployed positions. An extendible hoop may surround the extendible boom and is movable between the stored and deployed positions. A front cord arrangement may be coupled to the extendible hoop and defines a curved shape in the deployed position, and a reflective layer may be carried thereby. A rear cord arrangement may be behind the front cord arrangement and coupled between the extendible hoop and the extendible boom. The rear cord arrangement may include a rear plurality of interconnected cords defining rear polygons. Tie cords may extend between the front cord arrangement and the rear cord arrangement. A top cord arrangement may be above the reflective layer and coupled between the hoop and the extendible boom.
