| description | In this paper, a flat-top metasurface broadband mushroom antenna for microwave power transmission (MPT) is proposed. It has a <inline-formula> <tex-math notation="LaTeX">$4\times 4$ </tex-math></inline-formula> array of patches that are connected to the ground through vias to form a mushroom structure to reduce back lobe radiation. The antenna is fed by a microstrip, with the feeding slot located just underneath the central gap between the mushroom cells. This configuration enables the simultaneous excitation of dual resonance modes, resulting in aperture radiation and a wide impedance bandwidth. The final design has an overall dimension of <inline-formula> <tex-math notation="LaTeX">$1.96\lambda _{0} \times 1.96\lambda _{0} \times 0.09\lambda _{0}$ </tex-math></inline-formula> at 5.4 GHz. After simulation and measurement, The final impedance bandwidth is 4.2-7.0GHz (50%), the flat-top bandwidth is 4.2-6.3GHz (40%), the peak gain is 8.4dBi, and the stable 1dB flat-top beam bandwidths of the E-plane and H-plane from 4.2GHz to 5.4GHz are both greater than 67° and 38°, and the 3dB flat-top beam bandwidths of the E-plane and H-plane are both stably greater than 85° and 24° at 5.6-6.3GHz. The stable flat-top radiation pattern makes it more popular in microwave radio transmission. Compared with other works, this antenna has the advantages of broadband, compactness, and wide beamwidth. |
