Plot the 3-Dimensional Radiation Pattern, Plot of Azimuth and
Elevation radiation pattern of the Horn antenna....
Plot the 3-Dimensional Radiation Pattern, Plot of Azimuth and
Elevation radiation pattern of the Horn antenna. Simulate it for
the 100 MHz? What is the Directivity of the antennas. What is the
Beam-width and Sidelobe levels?
Find 10 (TEN) different antennas and draw the antenna and
radiation pattern in 3 dimensions. Make sure to specify the
coordinate system used and that both the antenna and pattern are
aligned with the coordinate system (no x,y, z shown in both, no
points awarded).
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.

2 A rectangular search radar antenna is 2.5m wide by 1.4m high.
It has an azimuth length efficiency of 0.78 and elevation length
efficiency of 0.65 and is operating at 13GHz. For this antenna,
calculate: a. Azimuth and elevation beam widths; b.
Effective aperture; and Gain c. If the elevation
efficiencies are improved to 100%, what is the effect on beam
width? Justify your answer.

Construct a time series plot. What type of pattern exists in the data?
The time series plot indicates a linear trend and a seasonal pattern
Show the four-quarter and centered moving average values for this time series.
Compute seasonal indexes and adjusted seasonal indexes for the four quarters.
