Processes and apparatuses for antenna frequency matching are disclosed. In one embodiment, a calibration process for an antenna having radio-frequency (RF) radiating antenna elements comprises: determining resonance frequencies of RF radiating antenna elements in a group of RF radiating antenna elements; selecting voltages to apply to the RF radiating antenna elements to cause resonance frequencies to match between the RF radiating antenna elements in the group of RF radiating antenna elements when the voltages are applied; and storing, in memory of the antenna, voltage information indicative of the voltages for driving the RF radiating antenna elements in the group.
