However, when the antenna device of the base station is dual-polarized: line k, two dual-polarized antennas can be generated. Orthogonally polarized signals. The structure design of the dual-polarized antenna is quite complicated, and – the antenna addition, the impedance matching, the size and the polarization_conformity need to be considered, and the β fabrication and assembly process are relatively difficult. Furthermore, the dual-polarized antenna uses two pairs of orthogonal half-wave oscillators, and the field patterns of the two pairs of half-wave oscillators are orthogonal to achieve the purpose of dual polarization. Specifically, the transmitting end of the dual-polarized antenna is equipped with a vertically polarized and horizontally polarized (four) transmitting antenna, and the purely terminal (four) direct polarized and horizontally polarized (four) receiving antennas can obtain two signals. The polarization component EX# Ey whose characteristics are not related to each other. The so-called directional dual-polarized antenna is to vertically polarize and horizontally polarize two receiving antennas (4) in a single-antenna body, and achieve spatial diversity (four) effects through pole-collected reception. Therefore, polarization diversity is spatial diversity. Special circumstances. The advantage of this method 3/12 M391732 is only a single-antenna, so it is compact and saves space in the device. The disadvantage is that its diversity reception is lower than that of the spatial diversity receiving antenna, and because the transmission power is allocated to two days. Online, will cause her work: power loss. In short, the gain of the antenna is low only by the above-mentioned two orthogonal half-wave oscillations, and the polarization of the antenna may be low. ± The creators of this case have finally proposed a structure that is reasonably designed and effectively improved in view of the above-mentioned structure shocked by the actual application of τ deficiency and accumulation of individuals engaged in relevant industry development practice for many years. 』 【New content】 The main purpose of this creation is to provide a design of a slotted structure on the structure of a double-polarized antenna structure antenna unit.
