- Abstract
In this work, a wideband magneto-electric dipole antenna with circular polarization is introduced, which covers the 2G, 3G, LTE, and 5G frequency bands. In the proposed antenna, a planar dipole antenna with triangular corners, which plays the role of an electric dipole with circular polarization radiation, is mounted on a vertically-oriented cavity, which acts like a magnetic dipole. A Y-shaped probe is used to excite the antenna, which improves the axial ratio (AR) diagram due to its unique geometry. A sample of the proposed antenna is fabricated, and its measurement results are presented. The measurement results show an impedance bandwidth of 81.46% from 2.35 to 5.58 GHz, which covers the entire bandwidth required for 5G applications. Also, the measured 3-dB AR bandwidth extends from 2.26 to 5.58 GHz (84.61%). The measurement results show a relatively stable gain over the whole band, with a maximum gain of 9.91 dB at 4.8 GHz. One of the most significant advantages of the magneto-electric dipole antenna is its high front-to-back ratio (F/B). This advantage is also achieved in the proposed antenna, resulting in a maximum measured F/B of 29.3 dB. The simulated and measured results show a good agreement.
