Technical Difficulties of Integrated Multi-Band WiFi, LTE & 5G Antennas

More wireless terminals integrate WiFi, LTE and 5G communication functions into one device, promoting composite multi-band antennas to be widely applied, while cross-frequency signal crosstalk becomes the core technical obstacle of product development. Different frequency bands have distinct wavelength features, increasing layout difficulty inside limited equipment inner space.Optimizing isolation between adjacent antenna terminals reduces mutual signal interference. Full-band sweep testing after sample completion ensures integrated antennas satisfy official communication specifications for civil and industrial wireless equipment.
