How do phased array antennas work
WebApr 10, 2024 · This method used a clover antenna phased array with steering capability to obtain high gain or wideband operation. Clover's phased array antenna can steer the beam to \(\pm 45^{ \circ }\) at the operating frequency ranging from 24 to 28 GHz. For simulation of the antenna, the CST tool was widely used and it attains a gain was about 9 dB. WebJul 14, 2024 · By definition, a the elements of a planar phased array are planar antenna elements, which are not isotropic: they have a unidirectional directivity perpendicular to the plane of the antenna. But let's say that G is the gain of each planar (e.g. patch) element in the orthogonal, or "broadside", direction ( θ 0, ϕ 0 ).
