In this article, a multi‐port one‐radiator antenna (MOA) is proposed for the effective design of octa‐band mobile antenna including the LTE secondary (penta‐band), GPS, and BT/Wi‐Fi (2.4 GHz and 5 GHz) band. The MOA is composed of one radiator, high‐pass filter (HPF), and two‐ports. The two‐ports connect to one radiator for the LTE secondary/GPS and the BT/Wi‐Fi band, respectively. To minimize the amount of interference between two ports, one port for BT/Wi‐Fi band has a gap coupled feed and HPF. The VSWRs and the efficiencies of octa‐band without and with the HPF have been measured and compared. The results show that the performance of integrated ports with the HPF is recovered to the same performance of isolated ports. These results indicate that the MOA could be an attractive solution as a compact antenna to cover LTE secondary, GPS, and BT/Wi‐Fi band at mobile terminals.
