  • Electrically short wide-band, wide-scan, slow wave dual notch radiator
    Patent number: 5828345
    Abstract: A dual notch radiating antenna includes a pair of notch cavities having respective slow wave structures extending into the notch cavities. The slow wave structures effectively shorten the length of the dual notch antenna. The dual notch antenna also includes a pair of front end impedance transformers respectively coupled to open ends of the notch cavities. A passageway is coupled between the impedance transformers near the open ends of the corresponding notch cavities. The passageway provides an alternative shorter path for leakage current from one notch cavity to the other notch cavity, thus greatly reducing the likelihood of an effective short circuit occurring at a signal supply port of the dual notch antenna.
