<P> Marconi was awarded a patent for radio with British patent No . 12,039 , Improvements in Transmitting Electrical Impulses and Signals and in Apparatus There - for . The complete specification was filed March 2 , 1897 . This was Marconi 's initial patent for the radio , though it used various earlier techniques of various other experimenters and resembled the instrument demonstrated by others ( including Popov ) . During this time spark - gap wireless telegraphy was widely researched . In July , 1896 , Marconi got his invention and new method of telegraphy to the attention of Preece , then engineer - in - chief to the British Government Telegraph Service , who had for the previous twelve years interested himself in the development of wireless telegraphy by the inductive - conductive method . On June 4 , 1897 , he delivered `` Signalling through Space without Wires '' . Preece devoted considerable time to exhibiting and explaining the Marconi apparatus at the Royal Institution in London , stating that Marconi invented a new relay which had high sensitiveness and delicacy . </P>
