It acts as a bridge or coupler between a guided transmission line (like a coaxial cable or waveguide) and an unbounded medium (free space).

A graphical representation of the radiation properties (like power or field strength) as a function of spatial coordinates. Usually, it consists of a main lobe (the primary direction of radiation) and side or back lobes (unwanted radiation in other directions). Slide 11: Yagi-Uda Antenna If you are compiling
Elements are fed with a progressive phase shift ( ), causing maximum radiation along the axis of the array.
Single wire antennas provide broad omnidirectional coverage. For long-distance communication, point-to-point links require highly directional beams, achieved by grouping individual antennas into arrays.
