The invention provides an electromagnetic generation device and microwave equipment. The electromagnetic generating device comprises an anode piece and a cathode piece, a cathode cavity and a resonant cavity communicated with the cathode cavity are defined by the anode piece, a tuning part is arranged on the cavity wall of the resonant cavity, and the electric size of the resonant cavity is adjusted through the tuning part; and the cathode piece is arranged in the cathode cavity. The electromagnetic generation device provided by the invention can reduce the electromagnetic wave frequency.

An ultra-wideband end-fire antenna with a common aperture embedded in a metal carrier includes a metal cavity with a coaxial cable compartment on one side. A radiator module is connected to the bottom of the metal cavity via a radiator fixing slot. The radiator module includes a common aperture antenna substrate. A low-frequency radiator is printed on the side of the common aperture antenna substrate closer to the coaxial cable compartment, and a high-frequency radiator is printed on the side farther from the coaxial cable compartment. This invention utilizes a dual-band antenna in a common aperture design to enhance the channel capacity and anti-fading capability of the communication system. At the same time, by achieving the antenna's carrier conformal characteristics, high isolation, and miniaturization, it enriches the antenna's application scenarios and improves the overall performance of the communication system.
