| Abstract: | To meet the requirements of building the indoor base station and beautifying the environment of district wireless communications, a dual-band tapered slot horizontal omni-directional antenna was proposed experimentally based on tapered slot antenna theory, geometrical theory of diffraction and rotating field theory. The proposed antenna is composed of four wideband tapered slot antennas, one dual cone reflector and power divider. The radiation pattern in vertical plane is compressed and thus a higher gain is obtained. The experimental results show better radiation and higher gain. The antenna can be applied to wideband, dual-frequency, and multi-frequency wireless communications. The proposed antenna can offer practical guidance to engineering application. |
