    摘要： This application provides an antenna and a communication device, and relates to the field of communication technologies, to solve a technical problem of a limited coverage of the antenna. The antenna provided in this application includes a dielectric substrate, a folded dipole, and N symmetrical dipoles. A combined line is disposed on the dielectric substrate, and the combined line has a first end and a second end. The folded dipole is located at the first end of the combined line and is connected to the combined line. The N symmetrical dipoles are disposed on the dielectric substrate, and the N symmetrical dipoles are connected to the combined line. The N symmetrical dipoles are sequentially arranged from the first end to the second end of the combined line. In an antenna provided in this application, bandwidth control of different frequency bands is implemented together by a folded dipole and a symmetrical dipole, increasing an operating bandwidth of the antenna. In addition, coherent superposition can be implemented, by arranging the folded dipole and the symmetrical dipole according to a specific size requirement, on an electromagnetic wave generated by the folded dipole and the symmetrical dipole, achieving a multi-beam characteristic and further achieving omnidirectional coverage of the antenna.

    摘要： Embodiments of the present invention provide a data modulation method and apparatus. The method includes: recognizing a type of data to be sent, where the data to be sent includes multiple types of data; and carrying at least one type of data in the data to be sent in a highly robust symbol, and carrying other types of data in the data to be sent in a common symbol, where the highly robust symbol is a symbol that has higher anti-noise and anti-interference capabilities than the common symbol. By means of the technical solution in the embodiments of the present invention, depending on the type of the data to be sent, the data to be sent can be carried in the highly robust symbol or the common symbol for sending. Therefore, different types of data are separately carried in different symbols for sending, and efficiency of data management can be effectively improved.
