Embodiment
Because described annular super wide band plane printed antenna works in microwave frequency band, its radiation theory will be analyzed by microwave transmission line theory here.Suppose that the external diameter of paster antenna circular ring-shaped radiation unit is half wavelength lambda/2, the thickness of medium substrate is L
3.Like this, circular ring-shaped radiation unit, medium substrate and ground plate can be regarded as the long Low ESR microstrip transmission line for λ/2, and form open circuit in radiating element edge.Again because dielectric substrate thickness is much smaller than wavelength X, thus electric field is substantially unchanged along the component in paster plane normal direction.When only considering principal-mode excitation, electromagenetic wave radiation can be thought to be opened a way by radiating element substantially, and the edge at position causes.The electric field of open end can be decomposed into the horizontal component along paster plane and the vertical component being parallel to plane normal, wherein vertical component is cancelled out each other mutually on the contrary because of phase place, therefore the horizontal component of electric field makes radiating element open end be equivalent to the annulus of cophase detector on infinity plane.Like this, radiating element to external radiation just equivalence become the radiation in gap.
