【Abstract】 With the continuous evolution of modern communication, the demand for microstrip patch antennas in the millimeter-wave frequency spectrum has been expanding. This paper presents a design for a wideband microstrip patch antenna tailored to the 77GHz-81GHz frequency range. By employing characteristic mode analysis, a thorough exploration delved into the resonance characteristics and current distribution of the microstrip patch antenna structure,offering a detailed analysis of the corresponding characteristic mode parameters. Subsequently,adjustments and optimizations were applied to the microstrip patch antenna structure to enhance specific characteristic modes. In conclusion, simulations, incorporating excitations, demonstrated that the microstrip patch antenna exhibited commendable gain, with a maximum gain reaching10.6dBi..更多还原
