Mobile 5G Device Antenna Tuning Demystified

5G is bringing a significant increase in new bands that mobile antennas must support. More than ever before, there’s a need for handset designers to use more aperture tuners on a single antenna due to the complexity of the new phone designs. While each addition of an aperture tuner helps optimize the overall antenna performance for each band, it sometimes comes at the cost of antenna efficiency. Without the proper balance of antenna efficiency and performance of each band on an antenna, the overall device performance and range will suffer.
