摘要: Disclosed is a multiple meander strip monopole antenna, which can have a broad bandwidth and easily miniaturize the antenna by using a meander structure. A grounding conductor plate is coupled to the under face of a dielectric base plate. A radial cross-strip is disposed symmetrically at the center of the upper surface of the dielectric base plate. Each radiating member of a multiple radiator is connected to the end portion of each corresponding branch of the radial cross-strip and stands substantially perpendicular to the base plate. Each radiating member is composed of a vertical strip section having a tapered structure, in which its width is progressively widened upwardly for an impedance matching and at least one meander strip section connected integrally to the upper end of the vertical strip section. When a feeding is carried out at the center of the radial cross-strip, a signal radiated from the multiple radiator is cancelled out in the axial direction of θ=0° and a radiation gain is increased as θ increases, thereby providing a conical beam radiation pattern. A broad bandwidth from 2.9 GHz to 10.85 GHz can be achieved and an excellent monopole radiation pattern having the same gain in all directions can also be achieved.
