FIELD: electricity.
SUBSTANCE: micro-strip antenna with switched polarisation refers to microwave equipment and can be used in paths of receiving and transmitting communication, radar and radio navigation systems. Device includes metal strip emitter with a branch to coaxial cable, and flat metal shield, between which there is dielectric medium with controlled electromagnetic characteristics, for example liquid crystal, ferroelectric material, ferromagnetic material, etc.
EFFECT: increasing upper limit of working frequencies of antenna and simplifying electronic control circuit.
