Embodiments are directed configurations of antenna elements for conformal phased arrays (e.g., circular or cylindrical) to support either omnidirectional or directional high-gain beams. Antenna elements may be spaced about a circle or cylinder with a vertical and circumferential element spacing that is based on a wavelength of an operational frequency. Such a configuration of antenna elements enables easy scaling to different frequency bands and a straightforward extension from single-linear to dual-linear polarization. Furthermore, the antenna elements and their configurations enable conformal phased arrays to be formed as one integrated structure or with multiple modular structures.
