MULTI-ELEMENT ANTENNA LINEAR DISCRETE DIGITAL MODULE Russian patent published in 2017 - IPC H04R1/44 

FIELD: radio engineering, communication.

SUBSTANCE: multi-element linear antenna discrete digital module containing pressure receivers, the outputs of which are connected to the inputs of the respective signal processing devices located at a certain interval along the module, the outputs of the signal processing devices being connected to the inputs of the information transmission device and its output connected to the communication line, the multi-element linear digital discrete digital module is made sealed. As pressure receivers, capacitive sensors are mounted on the printing circuit board, in which signal processing devices in the form of a single chip, which additionally performs the function of directly measuring the change in capacitance, are arranged in close proximity, the circuit boards being fixed to a box-type supporting base. On the conductors of the printing circuit board, power is supplied to the signal processing devices and the pressure receiver, the synchronization pulse and the output digital code.

EFFECT: increasing the conversion efficiency in the low-frequency area of the impact spectrum.
