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
Radio Marconi the development of proprietary technologies in 2006 and started its international expansion, with the first international project realized in 2007 at the Oslo Opera House. The company made a patent application in Italy in November 2007. In 2009, it further developed technology aimed at low consumption multimedia technology (known as MODE23). Patent applications were expanded to Europe, United States, Canada, China, Oman, Qatar and United Arab Emirates. In 2010, the company obtained a patent for its MODE23 technology in its native country. Its applications extend to other parallel markets, such as those involved with sport. In 2011, Radio Marconi was
