Antennas, in essence, channel electrical power into electromagnetic signals. The shape, size, and connectorization all affect the antenna radiation pattern. Two key parameters in assessing the performance of an antenna are directivity and gain\u2015directivity is a measurement of the concentration radiation in a direction while gain represents the power [&hellip;]","thumbnail_url":"\/blog\/wp-content\/uploads\/2017\/02\/Figure1.jpg"}
