This paper presents a novel one-dimensional (1D) frequency scanning dual-slot-waveguide array antenna with versatile advantages such as large scan volume. high frequency sensitivity. low cross-polarization and low sidelobe. Electromagnetic waves radiate through the leaky-wave dual slots. https://www.bekindtopets.com/limited-stock-Original-U-S-Vietnam-War-Era-Operation-Igloo-White-Seismic-Sensor-Inert-Rocket-great-price/
