Dipole antenna other monopole) antennas on the basis of dipole antennas of which they are one half. German physicist Heinrich Hertz first demonstrated the existence of radio waves in 1887 using what we now know as a dipole antenna (with capacitative end-loading). On the other hand, Guglielmo Marconi empirically found that he could just ground the transmitter (or one side of a transmission line, if used) dispensing with one half of the antenna, thus realizing the "vertical" or monopole antenna. For the low frequencies Marconi employed to achieve long-distance communications, this form was more practical; when radio moved to higher frequencies (especially
Enrico Marconi Enrico Marconi Enrico Marconi, known in Poland as Henryk Marconi (7 January 1792 in Rome – 21 February 1863 in Warsaw), was an Italian-Polish architect who spent most of his life in Congress Poland. Initially he was taught by his father Leander, later on, between 1806 and 1810, he studied both at the University of Bologna and at the Academy of Fine Arts of Bologna. In 1822 he was commissioned by general Ludwik Michał Pac to complete his palace in Dowspuda (then in Congress Poland, now in north-eastern Poland). He settled in Warsaw, where from 1827 he worked for the
