The number of antennas mounted on vehicles keeps growing. Antennas in hidden modules will replace or supplement antennas in shark-fin modules. Chassis antenna cavities were recently proposed as large antenna modules, which can be built, and concealed, inside the vehicle chassis. Recent results of multiple antennas inside a chassis antenna cavity are presented. An inverted-F antenna and a conical monopole antenna are compared, based on measurements performed in an anechoic chamber. Measurements suggest that the position of the antenna inside the cavity has a significant influence on the gain pattern. Further measurements of frequency sweeps are needed, but prior to that exchangeable cavity bases are required.
