The invention relates to an antenna
assembly and a vehicle. The antenna
assembly comprises a
dielectric body, a first antenna structure, a second antenna structure and a
metal frame body. The projections of the plurality of second antenna structures on the
dielectric body along the thickness direction of the
dielectric body are arranged around the circumferential direction of the first antenna structure, the plurality of second antenna structures are rotationally symmetrical about the center of the first antenna structure, and each second antenna structure is coupled with the first antenna structure. The
metal frame body is arranged around the periphery of the first antenna structure, and the
metal frame body is connected with the
dielectric body. The low-profile antenna structure is realized, the influence caused by the
surface wave effect of the
dielectric body is improved, the mutual
coupling interference between double frequencies is reduced, and the
antenna gain and the
antenna bandwidth are improved. Besides, the metal frame body can restrain back lobe level energy,
capacitance coupling is formed between the first antenna structure and the metal frame body,
capacitance coupling is formed between the second antenna structure and the metal frame body, the
antenna miniaturization design is further achieved, the overall size is reduced, and the installation space can be prevented from being limited.
