For instance, a phased array consists of two or more simple antennas which are connected together through an electrical network. This often involves a number of parallel dipole antennas with a certain spacing. Depending on the relative phase introduced by the network, the same combination of dipole antennas can operate as a "broadside array" (directional normal to a line connecting the elements) or as an "end-fire array" (directional along the line connecting the elements). Antenna arrays may employ any basic (<answer>omnidirectional or weakly directional</answer>) antenna type, such as dipole, loop or slot antennas. These elements are often identical.
What are the two standard antenna types?
omnidirectional or weakly directional
