摘要： A communication antenna and radiation unit thereof with tapered clearance slots for transceiving radiation signals disposed at four corners of the radiation unit. The slots form groups and are arranged and fed by two feeding units. A middle portion of the radiation unit is a flat central platform. Peripheries of the radiation unit are turned up to form folded edges. The communication antenna includes a reflecting plate and a radiation unit operating at a low frequency. The central platform has a high-frequency radiation element. The radiation unit has a small aperture and is lightweight, so the antenna size is reduced, and a radiation performance indicator can be ensured. The radiation unit is applied to a multi-frequency antenna, has little effect on a high-frequency oscillator, and is especially suitable for a multi-frequency base station antenna with a low-frequency unit and a high-frequency unit forming an array in a nested manner.

摘要： An integrated antenna unit where two dual-polarized radiating elements are connected on a PCB serving reflecting board as well as a filter lid of two-band pass filters. Each of two band-pass filter is connected directly to a two-way power splitter serving connection of same polarization from the two radiating elements. Two walls running parallel are extending at the band-pass filter edges to support the cavity of the filters and at same time serving as reflecting walls enabling to control the 3 dB azimuth beam generated by the radiating elements. Next, a multi-array antenna by collocating multiple arrays of the integrated antenna units.

摘要： A wideband dual-polarized radiation element includes two pairs of cross polarized dipoles and baluns which correspondingly feed current to each dipole in a balanced manner. Each dipole includes a pair of unit arms aligned on a top end of the corresponding balun. One end of each unit arm is connected on top of the balun, and the other end of one unit arm is bending inwards to form inward loaded line, and the other unit arm is bending downwards to form downward loaded line. An antenna includes a metal reflector and at least one wideband dual polarized radiation element, which has excellent radiation and polarization performance.
