WebAntenna Fundamentals I. Douglas B. Miron Ph.D, in Small Antenna Design, 2006 Half-Power Beamwidth. The half-power beamwidth (HPBW) requires both an intended direction and a plane of definition. For example, suppose we are at the center of coordinates and we want to transmit along the y axis with a horizontal dipole. We would orient the … 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. Radiation-enhancement properties of an X-band woodpile EBG and its application to a planar antenna. WebMost commonly, beamwidth is defined by either the half-power beamwidth (HPBW) or the null-to-null spacing of the main lobe (FNBW). To find the HPBW, we move 3 dB down from the peak and measure the …
