      alternating current (or voltage) to a dipole (two conductor) antenna. The frequency of thealternating current for the exercises in our study will be considered to be 2.4 gigahertz(2.4 GHz), which is an unlicensed frequency regulated by the FCC. In the present Wi-Fistandards another unlicensed frequency for use is 5 GHz .

      -174 dBm/Hz+10*log(40 kHz)+3.3 dB = -124.7 dBm Antenna Gain : 27 dB, Sidelobe rejection: -30 dB . Pattern : The RSM has a horn antenna for the receive and transmit path In this Report, a one way half power beam width of . 5° is assumed. The shape is approximated by a cos2 function as shown below.

      where t( , ) is the relative magnitude of the AUT pattern at any angle with respect to the maximum.2 For an isotropic radiator, t( , ) = 1, so that D = 1. For any real antenna, t( , )< 1 for much of the surface, resulting in D > 1. Directivity is the only term related to the antenna gain, which is solely a relative term.

      The net antenna gain is determined by adding the antenna gain to the line losses up to the reference plane. See Figure 3-10 and equations 3.8-13 to 3.8-18. The system temperature can be calculated from system losses from the reference plane to the receiver second IF bandwidth filter.
