Leaky-Waveguide Antennas TRIZ Cases

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.

A reconfigurable directional antenna uses an evanescent coupling edge with selectable electrical connections to steer electromagnetic radiation beams.

Discrete-dipole methods identify interaction matrices to optimize antenna configurations, reducing device complexity while maintaining optical performance.

Segmenting impedance elements eliminates complex voltage control networks and vias, improving operational bandwidth.

An air gap isolates scattering elements in a steerable beam antenna, reducing parasitic capacitance and scatterer losses at millimeter-wave frequencies.
