This image shows a horn antenna of the type used in microwave measurement and radar work. A horn’s flared aperture focuses energy into a narrow beam, and that directivity is why it serves as a reference in test setups, where repeatable readings matter, and as a practical radiator on radar ranges. Antenna Experts is a High Gain Horn Antenna manufacturer in India, supplies these antennas for wideband microwave use and also handles export orders for overseas buyers.
