Moreover, the role of multiband antennas becomes more important because the carrier aggregation technique of LTE-Advanced communication system has been released. Because each nation or wireless carrier uses different frequency bands, a multiband antenna is desirable. In various mobile communication services, long-term evolution (LTE) is one of the widely used communication systems as a fourth-generation wireless service. Nowadays, mobile equipment is required to cover various communication services (Wi-Fi, Bluetooth, GPS, and LTE). The overall dimension of the proposed antenna is 55 mm × 110 mm × 5 mm. The measured 6 dB return loss bandwidth is 169 MHz (793–962 MHz) at the low-frequency band and 1030 MHz (1700–2730 MHz) at the high-frequency band. The antenna provides a wide bandwidth to cover the hepta-band LTE/GSM/UMTS operation. The proposed antenna consists of a meandered planar inverted-F antenna with an additional branch line for wide bandwidth and a folded-loop antenna. This paper proposes a multiband antenna for LTE/GSM/UMTS band operation.
