Theoretical gain of a hertzian dipole
Webb12 okt. 2016 · An antenna that radiated equally well in all directions would have a directivity of 1 (0 dB.) The Hertzian dipole presented earlier has a directivity of 1.5 (1.76 dB), owing … WebbMicrostrip dipole antennas are modeled using arbitrarily oriented biaxially anisotropic substrates. The Method of Moments is used to compute induced currents and the results are used to calculate input impedance, resonant length and directive gain. We show that the orientation of the medium does affect performance metrics but at varying degrees …
