- . 30-dB, right-circularly polarized antenna in a radio link radiates 5-W of power t 2 GHz. The input impedance of this antenna is 75 ohms, and it is attached ɔ a 50-ohm transmission line. The receiving antenna has an impedance mismatch at its terminals, - which leads to a VSWR of 2. The receiving antenna is about 95% efficient and has a field pattern near the beam maximum given by E, = (2âx + jây) F, (0, 0). The distance between the two antennas is 4,000 km, and the receiving antenna Directivity is 100.
