Guglielmo Marconi's antenna (1901) Marconi's first transmitter,consisting of a copper sheet capacitive antenna(top)connected to a Righi spark gap (left)powered by an induction coil (center)with a telegraph key(right)to switch it on and off to spell out text messages in Morse code

Yagi-Uda antenna(1920s) The Yagi antenna was invented in Japan,with results first published in 1926.The work was originally done by Shintaro Uda,but published in Japanese.The work was presented for the first time in English by Yagi (who was either Uda's professor or colleague),who went to America and gave the first English talks on the antenna, which led to its widespread use.Hence,even though the antenna is often called a Yagi antenna,Uda probably invented it

Horn antenna (1930s) In the 1930s the first experimental research (Southworth and Barrow,1936) and theoretical analysis (Barrow and Chu,1939)of horns as antennas was done.The development of radar in World War II stimulated horn research to design feed horns for radar antennas.The corrugated horn invented by Kay in 1962 has become widely used as a feed horn for microwave antennas such as satellite dishes and radio telescopes. The first modern horn antenna in 1938 with Robert W.Wilson (left)and Arno A.Penzias inventor Wilmer L.Barrow. (right)stand in front of the antenna
