Description

We propose MEMS antenna with user hand grip sensing functionality for 5G mmWave phased antenna system. The device is called “SENTENNA” which stands for SENsor and anTENNA. The SENTENNA is fabricated on two glass substrates. The top metal patch fabricated on the glass acts as a radiation patch of antenna and an electrode of capacitance sensing simultaneously. The proximity-coupled microstrip patch antenna is designed and fabricated to operate at 28 GHz and capacitance variation on the patch is measured at 1 MHz. The performance of the designed SENTENNA is evaluated by HFSS and experimental.
