An antenna device, including a case assembly, a first waveguide assembly, and a second waveguide assembly, is provided. A cavity is defined by an interior of the case assembly, and a first side of the case assembly has a slot penetrating the case assembly. At least part of the first waveguide assembly is located within the cavity and is connected to the first side. A projection of the first waveguide assembly to the first side is symmetrically located on two sides of the slot. The second waveguide assembly is located outside the case assembly, is close to the first side, and is connected to the slot. The second waveguide assembly is suitable for transmitting an antenna signal to the cavity through the slot and the first waveguide assembly. The antenna signal resonates in the cavity and radiates outward from a second side of the cavity opposite to the first side.

Disclosed is an universal radio interface system that allows different types of radios to be installed on a mobile or stationary platform. After a radio is installed, the radio can be efficiently removed and replaced with a different type of radio without having to change cabling, connectors, or mounting hardware. The universal radio interface can include an universal interface housing that can be mounted to the mobile or stationary platform. The universal radio interface also includes a radio tray that is installed in the universal interface housing. The radio tray is configured to accommodate specific types or sizes of radio modules. The universal radio interface system can also include a radio tray backing affixed to the radio tray and the radio module. The radio module, radio tray, and radio tray backing are assembled and secured within an interior cavity of the universal interface housing.
