Exchangeable bases for rapid prototyping of carbon fiber reinforced polymer antenna cavities

Chassis antenna cavities were recently introduced as large, hidden, antenna modules. Testing different antenna configurations inside the module would require cutting several holes into the cavity floor. Manufacturing of several prototypes is not feasible, especially for carbon-fiber reinforced polymer chassis; flexible solutions are desired. Exchangeable cavity bases for chassis antenna cavities are proposed, designed and manufactured. Antenna measurements show the feasibility of the concept.
