Claim 0:
1. A multi-function module for mmWave communication and user input using mechanical switches, the multi-function module comprising:
an elongated antenna substrate;
a plurality of mechanical switches mounted to the elongated antenna substrate and distributed along a longitudinal length of the elongated antenna substrate, at least one mechanical switch of the plurality of mechanical switches being implemented as a radiating element for a mmWave patch antenna, the at least one mechanical switch connected to:
one or more digital switch lines for detecting a key press;
one or more radio frequency feedlines for detecting mmWave signals; and
a radio frequency choke in series with at least one digital switch line of the one or more digital switch lines to decouple the at least one digital switch line from at least one radio frequency feedline of the one or more radio frequency feedlines; and

one or more integrated circuit components mounted to the elongated antenna substrate and configured to use the at least one mechanical switch as the radiating element for the mmWave patch antenna to provide the mmWave communication.
