hi everyone,
The unit of gain for circular polarized antenna is dBic. However, there is no such function (dBic) in HFSS. Which function should I choose to derive correct unit for gain of circular polarized antennas? dB or dBc or something else? THX.
the field can propagate. However, transmission loss is large, especially when the permittivity is low.
besides, TEM mode can not be built as dual/multi conductors are necessary for TEM mode. Instead, I think the transmission wave is surface wave.
it depends on the transmitted power, the gains of the antennas, the efficiency of the rectify circuit and the resistance of the load, as well as the distance between the transmitted antenna and the received antenna.
Help!!!
I am interesting in rectenna. However, I don't know how to simulate rectenna.
Would anyone send me some tutorials on how to simulate rectenna?
Utilizing HFSS/Designer or ADS are fine.
Greatly appreciated!
it depends on those indicated by davenn.
besides, the size of the antena is important. make sure the transmit antenna and the receive antenna have the same polarizations.
EBG stractures
the stopband of an EBG operates in certain frequencies. in the stopband, it presents high impedances. the structure you present seens have no vias. for such a structure, no bandgap will observed, but in-phase reflection.
Hi, Every one
All the discussion on dispersion diagram is about symmetry structure (such the muchroom-like, square).
So, how to simulate dispersion diagram of a EBG with asymmetry structure (such as rectangular)?
feed the patch with an aperture will cause heavy backward radiation.
the U-slot and E-shape microstrip antenna is wideband antenna. you can download some paper from IEEE.
