Antenna Arrays TRIZ Cases
- Wideband Phased Array Reflector Antenna Variable Beamwidth
A phased array fed reflector antenna adjusts beamwidth by varying relative amplitudes of inner and outer feed elements.
- Travelling EM Wave Resonator for Substrate Dopant Activation
A travelling electromagnetic wave resonator exposes a substrate surface to parallel-propagating energy for dopant activation.
- Aperture-Coupled Microstrip Antenna for Circular Polarization
A microstrip antenna uses a ground plane slot to couple energy from the feedline to the radiator, generating circular polarization.
- Dual Polarized Antenna Array Beam Generation
Segmenting a dual polarized antenna array into sub-arrays with orthogonal feeds maintains beam stability despite phase and amplitude errors.
