Design the pyramidal horn antenna which operates at WLAN point
to point frequency. The horn antenna must have directivity of 22
and HPBW of 30 degree in E plane. Then, determine the power gain
(in dB) and the HPBW in H plane of this antenna. Please give your
opinion about this antenna.
A C-band station has an antenna with a transponder
gain of 54dB.The
transmitter output power is set to 100 W at a frequency of 6.10
GHz.
The signal is received by a satellite at a distance of 37,500 km
through
an antenna with diameter of 6m. The signal is then routed to
a
transponder with a noise bandwidth of 36 MHz, and a gain of
110dB
