Frequency Scanned and Leaky-Wave Linear Slot Arrays,ning techniques for compact arrays. In particular, methods used to enhance scan rates for slotted waveguide array antennas without sacrificing antenna gain and sidelobe levels are explored. The focus on scanned slotted waveguide arrays naturally lead to a need to address the rather different electro作者: 愉快么 時間: 2025-3-23 05:14 作者: Invigorate 時間: 2025-3-23 09:36
