The EIRP is the total power an ideal isotropic antenna would have to put out to provide the same signal strength as the Antenna Under Test (AUT) in the direction of the AUT's strongest beam.
In summary, the following evaluation criteria should be considered in order to quantify the design criteria: the half-power beamwidth of the main beam, side lobe distance, directional gain with respect to an isotropic antenna element, RMS performance for DF accuracy, and bandwidth.
At transmitter, if isotropic antenna is used, D =1 at this moment.
The SU-Tx is equipped with an ESPAR antenna, and transmits symbols to the SU-Rx, which is equipped with an isotropic antenna, while jointly keeping interference to N PU-Rxs (equipped with isotropic antennas) under a certain limit.
The directivity of an isotropic antenna was 1 since U and U0 were same.
For an isotropic pattern, antenna gain is low but the recognition range of tags is wide, so studies to enhance receiver sensitivity with isotropic antenna over a wide range have been carried out [12-15].
Considering the relationship between the equivalent isotropically radiated power (EIRP) and the power received by an isotropic antenna, it is possible to estimate the power density at the receiving point in scenarios that follow LOS COST-WI model, as (see Appendix)
In fact, every antenna is characterized by a density of radiation that can be calculated in the case of an isotropic antenna by equation:
The Base Station (BS) antenna used in this work is a computational two-element uncorrelated dual-polarized isotropic antenna. The antennas are located 0.5[lambda] apart from each other.
The SFA-S is an active broadband isotropic antenna combined with a portable USB-powered spectrum analyzer (manufactured by a third party to EMC Test Design's specifications).
