IPC: H01Q13/20
Filed: 2000-09-18
Granted: 2002-05-11
Abstract: A kind of planar array retrodirective reflector, which is formed by the assembly of using the combination of two substrate layers and the leaky-wave antenna array coupled and fed through microstrip aperture, is provided with two-dimensional (2-D) retrodirective effects. The upper substrate is used to design microstrip leaky-wave antenna for exciting the first order leaky-wave mode. The lower substrate is used to design a quasi-planar microstrip circuit for feeding the upper leaky-wave antenna. The medium between both mezzanines is a common grounding face that is a metal face; and an aperture is etched at the common grounding plate for coupling signal. Signal is fed in from the lower layer of microstrip line to excite the first high order leaky-wave mode of the upper layer microstrip through the aperture so as to reach the purpose of radiating the retrodirective wave. The number of aperture is determined by the amount of required leaky-wave array antennas. The present invention is a planar reflector that is effective for high retrodirective wave amount of incident source and is provided with the characteristic of wide scan elevation angle retrodirective wave. The advantage provided by the invention includes the followings: avoiding the complexity of connecting-wire network obtained in conventional reflector with two-dimensional effect; the retrodirective wave effect having wider scan elevation angle than the previously designed retrodirective-wave reflector; providing low cost, thin thickness, high portability; without adding the application structure of device, power source; having simple-connection wiring network to provide more empty member for externally adding active circuit; the design of a pile of array structure having 2-D retrodirective wave effect; the capability of separating the feeding circuit and leaky-wave antenna to have optimized design; and placing the metallic grounding face at the medium between the leaky-wave antenna face and the feeding rear-stage circuit face to have the best isolation effect capable of avoiding poor phenomenon of to improper mutual coupling.
