SYSTEM FOR RADIO COMMUNICATION WITH MOBILE OBJECTS Russian patent published in 2014 - IPC H04B7/26 

FIELD: radio engineering, communication.

SUBSTANCE: mobile objects include: a unit for determining the position of a mobile object in space, a high-frequency switch, K inputs/outputs of which are connected to inputs/outputs of K on-board broadband radio-frequency modules, and n of the K inputs/outputs (n=1, 2, 3, …; n<K) to inputs/outputs of n groups, consisting of K corresponding duplexers; combined inputs/outputs of each group of the K duplexers are connected to a broadband antenna, the (K+1)-th duplexer with radio-frequency inputs/outputs for radio-electronic equipment is also connected to the corresponding broadband antenna.

EFFECT: high reliability of transmitted information in air-ground channels in metre and decimetre ranges during manoeuvre of a mobile object and fewer receiving and transmitting antennae of the mobile object.
