Design of a Multiband Antenna for LTEGSMUMTS Band Operation

الملخص EN

This paper proposes a multiband antenna for LTE/GSM/UMTS band 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.

The antenna provides a wide bandwidth to cover the hepta-band LTE/GSM/UMTS operation.

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 overall dimension of the proposed antenna is 55 mm × 110 mm × 5 mm.
