Abstract
AbstractIn this letter, a compact magneto‐electric (ME) dipole antenna is designed and analyzed without compromising too much good performance of the ME dipole. In particular, the second‐order Minkowski‐like fractal structure is loaded on the planar electric dipole to effectively miniaturize the aperture size of the antenna. A prototype was fabricated and measured. The antenna volume is reduced by 24.6% when compared with the counterpart before the fractal. Meanwhile, the proposed antenna can achieve a bandwidth of 56% in terms of −10 dB ranging from 1.58 to 2.81 GHz. The radiation pattern of E‐ and H‐planes are basically identical. The cross‐polarization level is less than −25 dB, and the front‐to‐back ratio is larger than 14 dB. The maximum antenna gain can be up to 10.1 dBi. The measured results are in good agreement with the simulated ones.
