A slim vertically polarized omni-directional feed circuit integrated loop slot antenna for mobile base station is proposed in this paper. Picocell antenna requires a compact and slim structure, because its construction space is limited in urban areas. The proposed antenna consists of loop slots and patches to improve omni-directional pattern and bandwidth. In order to enhance the directivity gain,...
In this paper we propose a horizontally polarized antenna with omni-directivity in horizontal plane to use for reference antenna. Ripple coefficients of the radiation pattern in horizontal plane improve to ±0.1 dB. The theory of characteristic modes is used to analyze and illustrate the reason of the excellent omni-directivity property of the proposed antenna.
In this letter, we propose a horizontally polarized antenna with omni-directivity in horizontal plane. Ripple coefficient of the radiation pattern in horizontal plane improves up to dB. The theory of characteristic modes is used to analyze and illustrate the reason for why the omni-directivity property of the proposed antenna improved. Finally, we verify the antenna performances by experiment.
In this paper we propose a horizontally polarized antenna with omni-directivity in horizontal plane. Ripple coefficient of the radiation pattern in horizontal plane improve to ±0.1 dB. The theory of characteristic modes is used to analyze why the omni-directivity property of the proposed antenna increased comparing with that before optimization.
