摘要: An antenna to cover the LTE700 and GSM850/900 frequency bands (i.e. 700-960MHz) for a typical handheld mobile communication device is presented. The design challenge relatively short system ground plane which only 75mm long, relying on smartphone touchscreen as plane. In order obtain high bandwidth potential with single feed, grounded parasitic element used in conjunction main excited strip. manufactured using Laser Direct Structuring technology plastic piece. connection between PCB done thanks two pogo-pins placed underneath To tune desired bands, matching network consisting of lumped elements was at feed. target band (i.e covered reflection coefficient below -6dB both simulations measurements. total efficiency measured be higher than 45% whole bandwidth.
