The behavior of the proposed antenna has been investigated by studying different parameters to achieve the maximum gains of 6 and 7.7 dB in LTE band 3 and band 7, respectively, with optimal size. Measurements indicate that the antenna operates from 1.71 to 1.9 GHz and from 2.5 to 2.7 GHz with | S 11| < -10 dB. A trapezoid-shaped director is employed to achieve maximum gain over the required frequency bands. The dipole, operating in the lower band (centered at 1.8 GHz), is elliptical-bow-tiein shape with rounded edges, whereas a J-shaped dipole enables its operation in the upper band (centered at 2.6 GHz). It is designed on a low-cost FR4 substrate with a dielectric constant 4.6, loss tangent of 0.02, and thickness of 1.6 mm. ![]() A printed Yagi-Uda antenna with two closely-spaced driven dipole elements and truncated ground plane is presented for dual-band operation.
