A novel mobile terminal antenna covering the low LTE and GSM850/900 communication standards (i.e 700-960MHz) is proposed. The two-port antenna is composed of two coupling elements manufactured on a plastic piece using a laser direct structuring technique. To obtain a high port-to-port isolation between the two feeds, a neutralisation technique is applied. Simulated reflection coefficients and total efficiencies are compared to the measured data showing good agreement and competitive performance.
