kytkentäelementti sähk¦magneettisen coupling device to connect the external antenna to implement and walkie talkie

摘要

The antenna (D) of a radio telephone radiates electromagnetic RF radiation which is directed to a dielectric body block (10) according to the invention. By means of an inner and an outer conductor (1, 2) formed on the surface of the block a signal carried by the electromagnetic radiation is coupled to a coaxial cable (12) which takes it to an external antenna.
