Grid bracket structure for mm-wave end-fire antenna array
Bracket structures that structurally support and enhance the performance of millimeter-wave tapered-slot end-fire antennas for use in vehicular radar systems. The system includes a first longitudinal rib and a second longitudinal rib, each defining a first longitudinal slot and having a transmission end and a chip connection end. The system includes a crossbeam coupled to the first longitudinal rib and the second longitudinal rib. The system includes a first end-fire antenna having a transmission end that is received by the first longitudinal slot and a chip connection end. The first end-fire antenna is designed to transmit a first signal having a first phase. The system includes a second end-fire antenna having a transmission end that is received by the second longitudinal slot and a chip connection end. The second end-fire antenna is designed to transmit a second signal having a second phase that is different than the first phase.
