Simultaneous Aerial Operations TRIZ Cases
- Electrically Small Antenna Tuning via Phase Detection
A differential current transformer compares loop antenna current to feedpoint voltage, generating a control signal for a servo loop that tunes variable capacitance.
- Antenna Impedance Matching via Segmented Radiators
Segmented radiators and an adjustable matching circuit resolve the trade-off between compact volume and poor impedance matching in notebook antennas.
- Multi-band Antenna Coupling via Conductor Pattern
A multi-band antenna device uses a conductor pattern to couple radiators for improved impedance matching.
- Metal Housing Notches for Wireless Antenna Radiation
Notched metal housing segments ground points to improve antenna radiation efficiency across multiple frequency bands.
