Abstract
A modified folded monopole slot antenna for 3G WCDMA (1.91 ∼ 2.17 GHz), 4G LTE (2.17 ∼ 2.67 GHz), 3.5 GHz 5G (3.42 ∼ 3.7 GHz) and Wi-Fi dual band (2.4 ∼ 2.484 GHz / 5.15 ∼ 5.825 GHz) was proposed for the first time. The proposed antenna is designed and fabricated on a FR-4 substrate with dielectric constant 4.3, thickness of 1.6 mm, and size of 35 × 60 mm2. The measured impedance bandwidth of the proposed antenna is 2910 MHz(1.84 ∼ 4.75 GHz) and 930 MHz(5.11 ∼ 6.04 GHz), antenna gain in each frequency band is from 1.811 to 3.450 dBi. In particular, it was possible to obtain a commercially suitable omni-directional radiation pattern in all frequency bands of interest.
