On the last day of CES, while still getting over some of the death curry that we foolishly ingested the night before, I had a meeting with SkyCross, who recently announced a new actively tuned multiband antenna module for smartphones. With LTE, the demand for more and more bands on a smartphone has and will continue to increase, which has at present driven OEMs to simply include more antennas, each tailored for a specific frequency. Remember that the geometry of an antenna defines its radiative properties and resonant frequency, which in turn affects gain at different frequencies. At present I’ve seen smartphones with as many as four or five antennas, which poses considerable challenge for engineering a device, as number of antennas and their...
