“…HPBW is usually denoted as ∆θ −3 dB , with θ being the azimuthal angle in the horizontal plane containing the axis with the elements of the ULA and −3 dB subscript referring to the fact that halving the power corresponds to a reduction by 3 dB of that power when being expressed in decibels. Over the past decade, the theory has been supplemented with a compact expression for the directivity of the binomial array antenna for an arbitrary d/λ ratio [29]. In [30], a study of a 10-element binomial array antenna for Global System for Mobile Communications applications is described.…”

This research extends the theory of binomial array antennas. A closed-form expression for the half-power beamwidth of the array factor of an array antenna is presented. The expression is correct for the ratios of element spacing to wavelength greater than or equal to one quarter. Also, exact equations for determining the half-power beamwidth for main-beam steering are derived. A comparison with an approximate formula for the half-power beamwidth of binomial array antennas is carried out.
