T. Milligan et N. Herscovici, LOW-SIDELOBE ARRAYS FED BY A UNIFORM-DISTRIBUTION FEEDING NETWORK, IEEE antennas & propagation magazine, 39(3), 1997, pp. 72-74
Low-sidelobe arrays typically use feeding networks with appropriate am
plitude and phase distributions, which, in some cases, can be lossy an
d narrow-band as a result of their complexity. In the new approach pre
sented in this payer, a simple uniform distribution feeds the array el
ements, which are not uniformly positioned in the traditional uniform
grid. The location of the array elements is such that the sidelobes of
the array factor are ''pushed'' in the end-fire direction. There, the
element pattern is low enough in amplitude to effectively suppress th
e array-factor sidelobes to the required level. The combination of the
simple uniform-distribution feeding network and the spatial distribut
ion of the array elements results in a simple design for a low-sidelob
e array.
