Abstract

The invention provides a radome, an antenna structure and a wireless electronic device. The antenna structure comprises a radome and a radiator located inside the radome; Where (n-1) *[Lamda]1 / 2 (H1 (n*[lamda]1 / 2, H1 denotes the thickness of the radome,[Lamda]1 denotes the propagation wavelength of the electromagnetic wave emitted by the radiator in the radome, and n is a positive integer; And / or,L=a*b*[lambda]0, L denotes the length of the line segment from the radiation surface of the radiator to the inner side of the radome, the centerline being a straight line perpendicular to the radiation surface of the radiator, [lambda]0 denotes the propagation wavelength of electromagnetic waves emitted from the radiator in air, a denotes a preset parameter, and b is a positive integer. In this way, the directivity and gain effect of the electromagnetic wave beam can be enhanced, so as to compensate the loss of the electromagnetic wave in the wireless transmission and achieve a longer wireless transmission distance, thereby improving the overall performance of the antenna structure, reducing the area, circuit complexity and corresponding cost required by the conventional design, and enhancing the overall competitiveness of the product.

Description

technical field [0001] The invention relates to the field of wireless propagation technology, in particular to a radome, an antenna structure and wireless electronic equipment. Background technique [0002] Due to the high-speed data transmission capability and high image resolution due to the large bandwidth of the millimeter wave, the application of the millimeter wave is becoming more and more popular and important. However, due to the high operating frequency of the millimeter wave, the propagation loss of the millimeter wave is relatively high during the wireless transmission process, and the wireless propagation distance is short. Therefore, the actual application needs to be presented in an array to achieve a higher antenna gain. To overcome the high propagation loss and achieve a longer propagation distance. In addition, in order to achieve the best imaging effect, it is often presented in the form of a millimeter-wave antenna array in practical applications to impr...
