  • Patent number: 10978811
    Abstract: Techniques described herein provide slot antenna arrays for a millimeter-wave communication system. One or more implementations form a slot antenna array by creating multiple slot antenna out of a metal band that surrounds an outer edge of a housing structure. Various implementations form the slot antenna array to support millimeter waveforms associated with the millimeter-wave communication system. To form the antenna array, one or more implementations capacitively couple a respective signal feed to each respective slot antenna using a stripline connected to an inner edge of the metal band, where the stripline provides isolation between the antenna array and hardware components included in the housing structure. In response to coupling the signal feeds to the slot antenna, various implementations transmit a beam-formed wireless signal associated with the millimeter-wave communication system to enable successful data exchanges.
