Comparison of near-field beams between the uniform circular array (UCA) and uniform concentric circular array (UCCA), where a series of UCAs are employed to enhance the focusing ability to enable ...

Formulae are derived for calculating the field strength distribution for the types of broadside array normally used for short wave broadcasting, namely arrays consisting of rows of colinear half-wave ...

For some applications single element antennas are unable to meet the gain or radiation pattern requirements. Combining several single antenna elements in an array can be a possible solution. This ...
