摘要： A quadri-polarization diversity antenna system is disclosed.
According to embodiments of the present disclosure, an antenna system includes an antenna array including a first column of dual-polarized antenna units and a second column of dual-polarized antenna units. Each of the dual-polarized antenna units includes a first antenna element and a second antenna element perpendicularly crossing each other. In each column, the first antenna elements are conductively connected to form a first subarray and the second antenna elements are conductively connected to form a second subarray. The antenna system further includes an RF matrix that selectively adjusts phases of RF input signals to generate RF output signals provided to the subarrays. When the RF output signals are radiated by the dual-polarized antenna units, a first beam with +/−45° polarizations and a second beam with 0°/90° polarizations are formed, and the first beam and the second beam are formed toward spatially different directions from each other.

摘要： The present disclosure relates to an antenna RF module, an RF module assembly including the antenna RF modules, and an antenna apparatus including the RF module assembly. Particularly, the antenna RF module includes an RF module, a radiation element module arranged on a first side of the RF filter, and an amplification unit board arranged on a second side of the RF filter, an analog amplification element being mounted on the amplification unit board. A plurality of antenna RF modules constitute the RF module assembly, and the RF module assembly and an antenna housing constitute the antenna apparatus. Accordingly, a radome that interrupts dissipation of heat to in front of an antenna is unnecessary, and heat generated from heat generating elements of the antenna apparatus is spatially separated. Thus, it is possible that the heat is dissipated in a distributed manner toward the front and rear directions of the antenna apparatus. The effect of greatly improving performance in heat dissipation can be achieved.
