A micro-actuated metasurface leaky-wave antenna steers mm-wave beams over a wide range while avoiding the losses of conventional phased arrays.
Sparse surface wave transducers and tailored surface impedance suppress grating lobes while cutting phased-array complexity, power, and weight.
A micro-actuated stacked metasurface steers mm-wave beams over a wide range while avoiding the loss and complexity of conventional phased arrays.
Adjusting the air gap with a micro-actuator lets this metasurface switch and tune wave polarization and phase with low loss.
A dispersive lens corrects leaky-wave beam squint, enabling wideband high-gain steering without a complex mm-wave feed network.
A dispersive lens integrated with a leaky-wave antenna enables mm-wave beam scanning and wider bandwidth without a complex feed network.
Anti-phase feeding from opposite ends moves broadside radiation outside the open stopband, reducing standing-wave gain loss.
Air-gapped scatterers and monolithic switches cut parasitic and dielectric losses, enabling efficient millimeter-wave beam steering.
Variable sidewall dielectric thickness in an air-filled SIW antenna controls leaky-wave phase and amplitude while cutting dielectric losses.
