The sources of losses are: * Resistive losses * Resonance - energy can be trapped in a parasitic LC tank circuit and dissipate through resistances. * Substrate losses - if the thickness of the substrate is comparable to the $\frac{\lambda}{2}$, or half of the wavelength, some of the signal can travel through the substrate. ===== Design and simulation ===== The ANSYS HFSS suite can be used to design and simulate antennas. kb/antenna_design.txt Last modified: 2024-04-30 04:03by 127.0.0.1
