title = "Investigation of near field beam patterns for rotating arrays",
abstract = "The near field focusing capabilities for circularly rotating conventional monostatic arrays operating in the frequency band from 5 GHz to 15 GHz are studied. The impact of the inter-element spacing on the beam patterns and sidelobe structure of two different UWB arrays is investigated. The UWB beam pattern is also investigated for different inter-element spacing in the azimuthal direction. The influence of signal bandwidth on beam patterns is also studied. The results show that the array with non-equally distributed elements has lower sidelobe level than that with equally distributed elements. It is also shown that for sparse arrays the sidelobe level increases with inter-element spacing and the sidelobes move closer to the main beam.",
