The curtain array was usually composed of folded dipoles as elements for their high input impedance, but its bandwidth had a limitation for its antenna mode. This paper proposed a method for broadband folded dipoles using branch arms for current redi

Folded dipoles are typically used as elements in curtain arrays due to their high input impedance, but under this configuration, the bandwidth of the curtain array in antenna mode is limited. This paper proposes an improved folded dipole based on a b

Features of horizontally polarized curtain arrays over perfect earth are explicated through consideration of a vertical linear aperture, and a vertical linear array of isotropes. The ideal sinusoidal distribution, and sampled and binary excitations a

A multilayer dipole curtain array topology is presented and amplitude weights are synthesized to meet a specified sidelobe envelope. While direct optimization of the amplitude weights with a genetic algorithm meets the sidelobe requirement, the resul

The two-element array, which was investigated in the preceding chapter, may be regarded as the special case N = 2 of an array of N elements arranged either at the vertices of a regular polygon inscribed in a circle, or along a straight line to form a
