Abstract
Systems and apparatuses include a radio frequency feed configured to connect to a feedline, and a plurality of radiating elements coupled with the radio frequency feed. Each radiating element is arranged at an oblique angle relative to an antenna axis and configured to radiate at a wavelength (λ). The plurality of radiating elements define a phase center distance between about 0.15λ and about 0.2λ.
