Spherical array antenna
From the Rayleigh criterion, the directivity of an antenna, the angular width of the beam of radio waves it emits, is proportional to the wavelength of the radio waves divided by the width of the antenna. Small antennas around one wavelength in size, such as quarter-wave monopoles and half-wave dipoles, don't have much directivity (gain); they are omnidirectional antennas which radiate ra… Web11. apr 2024 · The aim of this work is to determine the complex excitation currents required to shape the array`s electric near-field E(r) to ensure user-specific and quasi interference …
