A Compact Coaxial Slotted-Cavity Feed Antenna with Shaped-Beam Pattern for High-Power Microwave Using Polarization Cancellation Techniques

The coaxial slotted-cavity antenna is an easily-manufactured, novel high-power microwave antenna developed specifically for its compact and shaped-beam characteristics. It can directly cascade with the high-power microwave source, and radiate linear-polarisation electromagnetic wave without extra power dividers and mode converters, which obtains a low profile. In this study, a double-layer coaxial...
