Metal Based Vivaldi Antenna & Antenna Array
Vivaldi antennas are wide-band antennas with excellent stable radiation patterns over wide frequency range and its based on metal make these very low loss. A wide band tightly coupled (WBTC) compact array of such antennas results in high gain, narrow beamwidth radiation pattern and can be used in all applications such as in detection of RF hidden devices, aerial /space borne radar detectors / locators (commonly known as ELINT systems), wide-band communication systems and can augment as spectrum sensor array as well.
