A multi-band Quasi-Yagi antenna based on loop excitation is presented with 68% miniaturization, which is achieved using loop meandering and a novel defected ground structure (DGS), targeting the 2 GHz band. It has a minimum measured −6 dB bandwidth of 249 MHz (0.780–1.029 GHz) in the lower band and 286 MHz (1.932–2.218 GHz) in the upper band covering several LTE bands. The proposed antenna ensures...
