Original Article


A flattop radiation pattern antenna with special-shaped array placement for large-scale stadium communications is presented in this paper. The antenna array consists of only 16 electric dipoles, each of that is ± 45° linear polarizations, placed in three rings configuration above a ground plane. Under the ground plane two feeding networks with ± 45° linear polarizations, respectively are used to divide signals to the 16 electric dipoles to produce flattop radiation patterns. A prototype operated at 2300–2700 MHz for stadium wireless communications, such as 4G LTE, is manufactured and tested, and good agreements between simulation and measurement are demonstrated. The measured gain is above 12 dBi and the side-lobe levels are lower than − 20 dB. The measured isolations between the two polarization ports are less than − 30 dB within the operating band. A fast beam ramp of less than 20° from − 3 to − 20 dB is achieved.
