This paper proposes a new design of a triple-band dual-polarized indoor base station antenna for mobile communication systems serving the 2G, 3G, 4G, and the new sub-6 GHz 5G applications.The design consists of two orthogonal dipole antennas to provide dual polarization.Each dipole consists of three different radiator types-elliptical dipole, bowtie dipole, and cat-ear shaped arms for different bands.

The proposed folk rivet sweat antenna offers three broad bands with the fractional bandwidths of 31.3% (0.7-0.

96 GHz), 55.3% (1.7-3 GHz), and 14% (3.

3-3.8 GHz) which can be controlled independently.The design also offers stable radiation patterns within the desired frequency bands, high polarization purity and, a simple feeding structure with a compact size and low profile which make this new design an ideal candidate for indoor mobile natio celebrate eyeshadow palette base stations serving the 2G, 3G, 4G, and the new sub-6GHz 5G applications.
