Ideal Receiving Antennas

An ideal receiving antenna is a tool that calculates the power that would be received by an ideal antenna. Use this type of antenna for a more computationally efficient solution.

Note: Ideal receiving antennas are supported by all solution methods, except FDTD.
The following types of receiving antennas are available:
RX far field antenna
The antenna is located at a point in space with the spatial receiving properties of a far field imported from simulated or measured data.
RX near field antenna
The antenna consists of near field apertures that serve as weights for receiving energy via the specified aperture points.
RX spherical modes antenna
The antenna is located at a point in space with the spatial receiving properties defined by spherical modes. The combination of the spherical modes effectively defines how energy is received, incident upon the antenna from any particular direction.
The following assumptions are made regarding ideal receiving antennas:
  • The antenna is considered to be matched (no mismatch loss is taken into account).
  • The antenna and model geometry are assumed to have no impact on each other during the solution phase (no coupling is taken into account).
