standard gain hornWe have measured the amplitude and the phase of the electric field on a planar area very near (about 0.3 wavelengths) to the aperture of a X-band standard gain horn antenna using a photonic sensor and transformed the aperture field distribution to the far field pattern. The...
An H-plane sectoral horn antenna is loaded with low-loss dielectric insertsn alternative embodiments so as to reduce beamwidth, increase axial gain and to achieve non-mechanical beam scanning. In one embodiment, the antenna is transverse... M Hamid 被引量: 21发表: 1984年 Parametric analysis of...
HPM measurement. The radiated HPM is measured by two receivers (one is fixed as a reference and the other one is shifted) in a fully anechoic chamber at a distance of 6 m from the phase center of the horn antenna. Each receiver consists of a standard antenna with gain of 12.6...
