Textile antennas woven into flexible wearable bands expand antenna space, reduce interference, and preserve signal quality during movement.
A smaller radial waveguide and adjusted terminal spacing enable microwave power combining without transmission mismatching.
Embedding conductive threads or liquid metal antennas in wearable bands improves flexibility, comfort, and signal durability under tight space limits.
An L-shaped feeding and parasitic antenna arrangement enables vertical polarization in a low-height wireless device without extra noise countermeasures.
Capacitive coupling and a tunable matching structure let a compact UHF RFID tag work on metal without ferrite, spacers, or resonant cavities.
A planar antenna with an embedded absorbent element senses fluid dielectric properties by resonant frequency shift while preserving accuracy.
Conductive vias raise antennas above the circuit to cut coupling, lower connection resistance, and preserve compact wide-band RF layouts.
Segmented metal-frame antenna sections maintain resonant frequency and radiation efficiency when hand contact would otherwise detune the frame.
An orthogonal open feed loop lets a monopole wire-plate antenna connect directly to differential RF transmitters without a balun, cutting size and losses.
A multiple antenna module positions a second antenna perpendicular to a first antenna on a printed circuit board.
Stacked conductive strips and vias form mesh patterns that reduce signal losses in compact millimeter-wave antennas.
