DESIGN BOARD microwave antenna system of upper-air radiosonde

摘要

The invention relates radio engineering and may be used in the construction of upper air radiosonde (ARP) to transmit telemetry information to a single carrier frequency may also be used to build highly stable and efficient transceiver systems.; Technical challenge: it is to improve the performance of radiosonde due to:; - creation of circuit-technical and constructive solutions, which allows to sharply increase the stability of the operating frequency, transmit power, sensitivity;; - technological transparency solve this problem;; - reducing the power consumption level from the power source by reducing the transmit power of the antenna and increase efficiency;; - low cost of hardware;; - construction of structural elements, integrates all the antenna-feeder and transmitting-receiving part, which greatly simplifies the setup process, and the ability, a complete harmonization of electronic components to each other, which reduces the GPC and increases the accuracy of the ARZ.; To solve the problem of the proposed design of microwave boards and antenna ARP system, comprising a base, a microwave fee and an antenna system, characterized in that the microwave-board secured to the base by means of screws, nuts and washers, with those screw contact when connecting to by soldering structure form the transition of the screw, which is fastened with the nuts through the grommet into the opening of the microwave board; and a base; on transition screw soldered antenna ARP system, and the antenna is in the form of an asymmetric quarter-wave vibrator having a shim is electrically connected with the vibrator, a sliding contact placed on the tube at a distance h from the cylindrical screen, wherein the shim is movable in the tube, for example, via a threaded connection by adjusting the distance h between the antenna and the cylindrical screen for adjusting the coupling coefficient of the vibrator to the collector of transistor microwave avtogenerato pa, and the length adjustment of the vibrator thus allows setting either inductive or capacitive nature of the antenna impedance.
