In the thesis, designs of dual-polarized antenna for base stations of CPE FR1 band are presented. The proposed designs can be applied for the 5G NR(New Radio) mobile communication applications. Two designs are proposed and discussed. The main structures of the proposed antennas are based on dual-polarized crossed dipole antenna, with low cost FR4 substrates. The first design is for the low-band base station at 0.698-0.96 GHz. In order to achieve compact size, metal coupling structure is used, making the operating frequency lower than other base station antennas of same size. The antenna is fed and supported by baluns. The second design is for high-band base station at 3.3-5.0 GHz. In order to cover all bands of interest, the dual-polarized crossed dipole antenna is designed by using bow-tie structure to obtain broadband response. In addition, and the two base station antennas are placed on the reflector to obtain unidirectional radiation.
The measured impedance bandwidths of the low-band base station antenna at ports #1 and #2 are 40.5% and 52.7%, respectively. The measured antenna gain is 4.3-6.0 dBi, and the measured port isolation is more than 17 dB. The measured impedance bandwidth of the high-band base station antenna at ports #1 and #2 are 54.7% and 53.1%, respectively. The measured gain is 6.0-7.5 dBi, and the measured port isolation is more than 27 dB. Both proposed antennas have sufficient antenna directivity and high gain for practical purposes. |
