Abstract

The invention belongs to the field of wireless communication, and particularly relates to a small broadband differential excitation dual-mode and dual-polarized base station antenna in this field. Theantenna comprises a first dielectric plate, a second dielectric plate a third dielectric plate, a reflection plate, a coaxial connector, a radiation patch, a driving branch and baluns. The first dielectric plate is horizontally arranged at the uppermost layer of the whole antenna; the reflection plate is horizontally arranged at the lowest layer of the whole antenna; the pair of mutually orthogonal baluns are arranged between the first dielectric plate and the second dielectric plate, and the first dielectric plate and the reflection plates are respectively perpendicular to the baluns up anddown; the orthogonal surfaces of the orthogonal baluns are respectively printed with the second dielectric plate and the third dielectric plate to allow the second dielectric plate and the third dielectric plate to be mutually perpendicular to the first dielectric plate and the reflection plate. The small broadband differential excitation dual-mode and dual-polarized base station antenna ensuresthe miniaturization while ensuring the broadband.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a small broadband differential excitation dual-mode dual-polarization base station antenna in the field. Background technique [0002] Dual-polarized antennas play a significant role in improving multipath fading and increasing channel capacity, so they are widely used as base station antennas. With the development of modern mobile communication technology, broadband, miniaturization, high isolation and low cross-polarization have become the mainstream trend of dual-polarized antenna design. In particular, the communication upgrade of wireless technology requires base station antennas to take care of multiple frequency bands and arrays of multiple frequency band units. This requires a single base station antenna unit to be as broadband as possible while keeping the size of the antenna small. [0003] Various dual-polarized antennas have appeared in recent years, which can b...
