FIELD

Field performs several calculations related to the EM fields from an antenna, including the following:

A: determine RF field strength from TX antenna gain and TX power.
B: determine TX power from RF field strength, and TX antenna gain.
C: determine RF field strength from power absorbed by a receiving antenna.
D: determine power absorbed by an antenna from RF field strength and ant gain.
E: determine path loss from RX and TX antenna gain.

Options A and B relate the field strength from a transmitting antenna to the antenna parameters.

Options C and D relate the field strength impinging on a receiving antenna to the antenna parameters and the RF power absorbed by the antenna.

Option E calculates the open field path loss for a pair of antennas.
