A Wideband ME Dipole Array with Stable Gain

A low-profile wideband magneto-electric (ME) dipole antenna array with stable gain is designed in this paper. First, the proposed ME dipole element realizes a wide bandwidth from 5.08 to 7.24 GHz (2.06 GHz, 33.4%), which exhibits two resonant modes. The microstrip line on the lower substrate is used to feed the slot and the three pair of dipoles on the upper substrate. Two rows of via connect the dipoles to the ground. Then, 1×4 ME dipole elements are used to construct the antenna array for high gain. The antenna array shows an impedance bandwidth (IMBW) of 5.1-7.07 GHz (1.97 GHz, 32.5%), with a stable gain from 10.8 dBi to 11.8 dBi. It is worth noting that the antenna profile height is only 0.08
