There is another type of line, which is usually used at very high frequencies: the slotline. Symmetry or impedance boundaries also. In this post we will study the waveguides using an FEM simulator such as HFSS, which is able to analyze tridimensional electromagnetic fields . simulator ANSYS HFSS. . The simple E-shaped monopole antenna results in a single resonance, and by loading the vertical arm of the antenna with narrow slots and stubs, a multi-band. EXCEPTION: When a Wave Ports edge touches a radiation boundary the edges. [HOST] - Download as a PDF or view online for free. These coupled lines are fed by microstrip lines, which are excited in the simulation using wave-ports, and terminated to constitute a. Antenna software HFSS (high frequency structure simulator) - Download as a PDF or view online for free. According to the. Like the slotline HFSS, which is able to. Slotline Antenna; Bonding Wire HFSS is in “Scully” c:/Otherprg/hfss/doc; Challenging setup for unbalanced or non-enclosed lines (microstrip, CPW, slotline, etc. ) Customer Training Material. Typically the edge boundary takes the boundary condition defined in the 3D geometry. The antenna is fed by a balanced microstrip-slotline and makes good use of space to reduce feeding network area and the size of antenna.
