Description

Balanced antenna

Technical Field

The present application relates to the field of antennas, and in particular to a balanced antenna.

Background

Dipole antenna feeding is an important issue in antenna engineering. The challenge is to provide a symmetrical feed from an asymmetric transmission line (typically 50 ohms impedance) to a half-wave dipole antenna (resonant input impedance of about 70 ohms). Balun is a means of achieving impedance transformation from asymmetric feed to symmetric feed. In practice this may be achieved in a number of ways. If the dipole antenna is fed by a coaxial cable, the simplest balun implementation is in the form of a sleeve that is shorted at one end of the cable outer conductor and open at the antenna terminal to form a quarter wavelength. This balun is called balun Zu Kaba.

The existing router antenna wraps the antenna because of more metal parts in the router installation environment and in internal spare parts, and the performance of the antenna is interfered, so that the receiving and transmitting performance of the antenna is affected.
