  • Patent number: 11575206
    Abstract: The present invention provides a self-filtering millimeter-wave wideband multilayer planar antenna. The antenna includes a first layer having a slot feed. A second layer includes at least a pair of probes fed by the slot feed from the first layer. A third layer includes at least two substantially planar radiating patches each patch respectively coupled to one of the probes on the second layer. The radiating patches are arranged to radiate a millimeter-wavelength electromagnetic wave when the slot feed receives excitation energy and transmits the energy to the radiating patch through the respective probe. The self-filtering antenna does not require a resonant cavity structure coupled to the radiating patches. Antenna arrays of arbitrary numbers of antenna elements may be constructed from the self-filtering antenna. Such arrays are particularly suitable for 5G mm-wave backhaul communications.
