Substantially Flat Resonant Elements TRIZ Cases

Voids, air bubbles, or dopants tune dielectric permittivity in a patch antenna array to widen bandwidth while preserving mechanical stability.

A 2×2 polygonal patch array with corner notches lets one frequency selective surface pass both 5G and 6G signals while lowering manufacturing cost.

A segmented metal-mesh transparent antenna uses capacitive and tuning segments to match CP bandwidths while preserving transparency.

Embedded MTM-EBG unit cells let a low-profile patch antenna switch resonance across GPS L1, L2, and L5 bands without added size.

A stacked PCB antenna uses through-hole coupling between radiators to remove the radome, cutting size and cost while preserving gain and bandwidth.

Light-controlled metasurface tuning steers microwave and MMW beams toward moving targets without complex control circuits.

A PCB-compatible metasurface uses phase-shifted meta-atoms to steer full-duplex beams without ferrites, weight penalties, or frequency change.

A central strip-wiring connection preserves main polarized-wave reflection while reducing cross-polarized reception in liquid crystal surfaces.

A parasitic element, patch, and through-via widen 25.6-29.8 GHz bandwidth while avoiding complex multilayer antenna fabrication.

Coupled second-harmonic oscillators and on-chip patch antennas raise THz radiated power while easing lens cost and heat dissipation.

Stub conductors around the patch create gap capacitance for impedance matching, boosting bandwidth, gain, and directivity in compact antennas.

A high-k dielectric member around the patch substrate boosts low-elevation radiation gain while keeping the antenna compact.

Integrated feeding lowers microstrip antenna thickness while preserving signal coupling.

Asymmetric feed structures with unequal electrical lengths produce symmetric radiation patterns, reducing beam offset and improving gain.
