WebThe half-power (-3 dB) beamwidth is a measure of the directivity of the antenna. Polarization, which is the direction of the electric (not magnetic) field of an antenna is another important antenna characteristic. This may be a consideration for optimizing reception or jamming. WebFor the EBG-covered antenna, the measured Half-Power Beamwidth (HPBW) is 12[degrees] in the E-plane and 14[degrees] in the H-plane; the Side-Lobe Level (SLL) is -9.84 dB in the E-plane and -13.15 dB in the H-plane.
