| Summary: | Abstract A simple wideband magneto‐electric (ME) dipole antenna is presented in this letter. In particular, two pairs of L‐shaped slots with different sizes are successively etched out of the pair of horizontal patches of electric dipole, which can enlarge the bandwidth of ME dipole antenna without increasing the antenna size. Two new resonant frequency points are generated respectively at the lower and upper frequency region. To improve the impedance matching characteristics, two vertical rectangular patches are loaded in the middle of the horizontal portion of the Г‐shaped feed structure. A prototype is fabricated and measured, and an overlapped bandwidth of 101.3% (from 1.36 to 4.15 GHz) in terms of VSWR ≤ 2 is achieved, which can simultaneously cover the n50 (1.432–1.517 GHz), n51 (1.427–1.432 GHz), n78 (3.300–3.800 GHz) and 52.5% of n77 (3.8–4.4 GHz) bands of sub‐6G. It should be highlighted that other excellent properties of ME dipole antenna, such as stable radiation pattern, high gain, and low cross‐polarization level (CRPL), are maintained, which makes the proposed ME dipole antenna a good candidate for sub‐6G applications. |
