The disc width is a very important parameter used in directional antenna. It refers to the antenna's radiation graph below the peak 3dB quarters of the width of the angle (the antenna's radiation map is a measure of the antenna in each direction signal ability to send and receive a indicator, usually graphically expressed as the power intensity and the relationship between the angle).
The vertical disc width of the antenna is generally related to the covering radius of the antenna corresponding direction. Therefore, in a certain range through the antenna verticality (pitch angle) adjustment, can achieve the goal of improving the quality of community coverage, which is our network optimization is often used as a means. It mainly relates to two aspects of horizontal disc width and vertical planar wave flap width. The half-power angle of the horizontal plane (H-Plane-Half Power Beamwidth): (45 °, 60 °, 90 °, etc.) defines the beam width of the antenna horizontal plane. The greater the angle, the better the covering at the junction of the sector, but when the antenna inclination is raised, the more prone to the beam distortion, the more area coverage is formed. The smaller the angle, the worse the overlay at the junction of the sector. Increasing the tilt of the antenna can improve the level of the sector at the junction of the coverage, and relatively speaking, it is not easy to generate more area coverage of other communities. In the city center base station because of the small station distance, the antenna inclination is big, should adopt the horizontal plane half-power angle small antenna, the suburb selects the horizontal plane half power angle big antenna; half power angle of the vertical plane (V-Plane Half-powered Beamwidth): (48 °, 33 °, 15 °, 8 °) defines the beam width of the antenna's vertical plane. The smaller the half-power angle of the vertical plane, the quicker the signal attenuation is deviated from the main beam direction, the easier it is to control the coverage by adjusting the inclination of the antenna.
