Abstract

Abstract:

In view of the limitation of the installation space and structure size of 5G antenna in satellite communication, this study realizes the miniaturization design of the satellite-borne 5G antenna based on the trapezoidal oscillator structure and L-shaped bending mode. By transforming the vibrator of the log-period antenna from a rectangle to a shorter-length trapezoid, two trapezoids combined with a 90° sector structure are used to further synthesize the antenna, and the vibrator structure is optimized to achieve a horizontal reduction in antenna size and a miniaturized design. The designed antenna is applied to a certain type of satellite platform, and the antenna coupling degree under different placement positions is studied. The results show that compared with the traditional structure, the transverse size of the miniaturized LPDA is reduced from 90 mm to 65 mm, and it has better port impedance matching characteristics and radiation performance, which can better meet the application requirements of compact load, lightweight and frequency band intensification in 5G satellite communication.

Key words: 5G, satellite communications, log-periodic dipole antenna, miniaturized antenna, return loss, radiation pattern, coupling
