I’m trying to study for my Electrical Engineering course and I need some help to understand this question.

Hi there,

I need help with my assignments and need to get them done by 03/28/2021. Here are the tasks:

Follow the design guidelines given in Antenna Magus, Course Material and teaching slides taught in class to design the following:

1. Design a 4×1 patch antenna array with corporate feed network at 2.5 GHz with FR4 substrate for inter-element spacing of 0.5 wavelength and 0.7 wavelength.

(a) Plot the reflection coefficient magnitude and 2D and 3D radiation pattern for both inter-element spacings.

(b) Compare the results for two different inter-element spacings in terms of resonant frequency, maximum gain, beamwidth and sidelobe level, and explain the results.

2. (a) Design a 8×1 patch antenna array with corporate feed network at 6 GHz with FR4 substrate and half wavelength inter-element spacing and plot the reflection coefficient magnitude and 2D and 3D radiation pattern. Explain the difference that you observe between phi=0 degree plane and phi=90 deg plane in radiation pattern.

(b) Design a 4×1 patch antenna array with corporate feed network at 6 GHz with FR4 substrate with half wavelength inter-element spacing and plot the reflection coefficient magnitude and 2D and 3D radiation pattern. Compare the performance with 8×1 patch antenna array of (a).

3. Design a simple Discone antenna with 5 GHz as center frequency and plot the reflection coefficient magnitude and radiation pattern. Find out the difference between a quarter wave monopole with 5GHz resonant frequency (design not required) and the Discone antenna. Can you design an ultra-wide-band Discone (search internet)?

Thank you so much!
