[Field of Industrial Application] The present invention relates to a high frequency transmission line switching device, and more particularly to a high frequency transmission line switching device that constitutes a monitor of an antenna device that monitors azimuth information given to an aircraft in an electronic scanning antenna device of a Takan navigation aid system. It is something. [Prior Art] The direction monitor of the conventional Takan navigation aid system receives a transmission signal in one direction radiated from the antenna by one monitor antenna located around 1 meter from the antenna, processes this received signal and determines the direction. Accuracy was monitored. [Problems to be Solved by the Invention] The conventional azimuth monitor described above has the disadvantage that it monitors only one direction and cannot monitor the azimuth of signals radiated in all directions. In particular, when using an electronic scanning antenna to monitor in all directions, the antenna is a multi-element cylindrical array type antenna, so a large number of monitor antennas spaced about 1 meter apart is required, and the entire antenna becomes large. Become. [Means and Examples for Solving Problems] The high frequency transmission line switching device of the present invention has 36 antennas located inside 36 antennas in order to monitor all directions.
Among the received signals of one pick-up probe, the received signals of 10 adjacent pick-up probes are switched in all directions in 36 directions, that is, every 10 degrees. The received signals selected by the high frequency transmission line switching device of the present invention are given an appropriate phase and combined, thereby making it possible to obtain an output equivalent to the received signal by the monitor antenna described above. The high frequency transmission line switch has 36 input terminals, 10 output terminals, 43 switching signal input terminals, and 90 PIN diodes.When the PIN diodes are forward biased,
Using the characteristics of low impedance and high impedance when reverse biased, 10 of the 36 inputs are selected according to the combinations shown in Table 1.
It has electrical switching to the output. FIG. 1 is a circuit diagram of an embodiment of the present invention. Input terminals 1 to 36 of high frequency signals received by the pick-up probe and these input terminals 1 to 36
