Abstract

The invention discloses a high-isolation dual-polarization E-type microstrip antenna with a spurious wafer. The antenna has the advantages of high isolation, low cross polarization, small size and simple structure. The antenna adopts a double-layer E-type patch form; E-type patches are respectively printed on both upper and lower surfaces of an upper dielectric slab; slotting directions of the E-type patches are orthogonal; and two linear polarizations in the direction of plus and minus 45 degrees are respectively generated by coaxial probe feed. The high-isolation dual-polarization E-type microstrip antenna has the biggest innovations that two E-type patches are respectively printed on both the surfaces of the same dielectric slab; a conventional single-polarization E-type patch antenna is expanded to a dual-polarization E-type patch antenne; and the high isolation and the low cross polarization characteristic are obtained. Under the condition that the return loss is lower than minus 15dB, the bandwidth of 7.7 percent can be reached, the isolation is lower than minus 30dB, a directional diagram is stable, the cross polarization is good, and the gain is in the range of 6.8dBi-7.4dBi. The high-isolation dual-polarization E-type microstrip antenna can be applied to a micro mobile base station.

Description

technical field [0001] The invention belongs to the technical field of antenna engineering, and relates to a dual-polarization microstrip antenna, in particular to a high-isolation dual-polarization E-type microstrip antenna that can be used for a miniature mobile base station. Background technique [0002] The pico base station (Pico) has the characteristics of small size, low power, light weight, easy to carry and install, and is suitable for hotspot areas and indoor coverage occasions. At the same time, the pico base station (Pico) can well solve the difficult problems of fast blind filling, hot spot traffic sending and receiving, and low-cost coverage encountered in current network construction. As a relay station between the base station and the mobile phone user, the micro base station (Pico) mainly receives, amplifies and retransmits the radio frequency signal of the local base station or the user's mobile phone to increase the field strength and solve various problem...
