You can solve the problem using Euler's formula to go from a polar (phasor) representation to a rectangular (real + imaginary) representation and then back to a polar (phasor) representation. The result is a rather complicated expression.....that doesn't mean it is wrong! (Handwrite and step by step solutions)

2.9. You are an antenna engineer and you are asked to design a high directivity/gain antenna for a space-borne communication system operating at 10 GHz. The specifications of the antenna are such that its pattern consists basically of one major lobe and, for simplicity, no minor lobes (if there are any minor lobes they are of such very low intensity and you can assume they are negligible/zero). Also it is desired that the pattern is symmetrical in the azimuthal plane. In order to meet the desired objectives, the main lobe of the pattern should have a half-power beamwidth of 10 degrees. In order to expedite the design, it is assumed that the major lobe of the normalized radiation intensity of the antenna is approximated by U(0, 4) = cos"(0) and it exists only in the upper hemisphere (0 <0 < x/2,0 <¢ < 2n). Determine the: (a) Value of n (not necessarily an integer) to meet the specifications of the major lobe. Keep 5 significant figures in your calculations. (b) Exact maximum directivity…

If the effective height of an areal is 1/150th of the wavelength, then estimate its radiation resistance. I need to submit the assignment tomorrow. Please help. Will rate thumbs up.
Q2 You are an antenna engineer and you are asked to design a high directivity/gain antenna for a space-borne communication system operating at 10 GHz.

In order to expedite the design, it is assumed that the major lobe of the normalized radiation intensity of the antenna is approximated by U (0, p) = cos" (0) And it exists only in the upper hemisphere (0 ≤ 0 ≤+2,0≤p≤ 2л).

ට General review of antenna geometries: - 1) Single-element radiators a) Wire radiators (single-element) straight-wire elements (dipoles/monopoles) wire antenna elements loops 31 о helices 0+000° Wire antennas are simple to make but their dimensions are commensurable with the wavelength. This limits the frequency range of their applicability (at most 1-2 GHz). At low frequencies, these antennas become increasingly large. b) Aperture antennas (single element) Aperture antennas were developed before and during the WW2 together with the emerging waveguide technology. Waveguide transmission lines were primarily developed to transfer high power microwave EM signals (centimeter wavelengths), generated by powerful microwave sources such as magnetrons and klystrons. These types of antennas are preferable in the frequency gro 20 GHz. c) Printed antennas The patch antennas consist of a metallic patch etched on a dielectric substrate, which has a grounded metallic plane at the opposite side. They…
Question 1 In this homework, you are supposed to design a WBFM generator using Armstrong method. The required WBFM should be able to transmit an audio signal of bandwidth 50HZ to 4kHz. Design an Armstrong indirect FM modulator to generate an FM signal with carrier 100 MHz and Af 200 kHz. A narrowband FM generator with fe = 100 kHz and 4f = 10 Hz is available. Only frequency tripplers are available as frequency multipliers. In addition, an oscillator with adjustable frequency from 22 to 26 MHz is also available for mixing, along with bandpass filters of any specification. Show your work to get full credit (labelled block diagram, complete calculations for local oscillator frequency etc.).
