Part A: Antenna and Circuit Simulation using AWR 1) Figure A1 shows a microstrip antenna with a 50 ohm feedline. WI い W L Figure A1a: Microstrip Antenna w1 2.95mm, 1120mm, L = 36mm, W = 40mm Simulate the microstrip antenna shown above using AWR. Use a frequency sweep from 2GHz to 3GHz. You need to use FR 4 substrate with a dielectric constant of 4.5 and a thickness of 1.575mm. (i) (!!) Obtain graphical results a. S11 versus frequency b. Real(Z11) versus frequency c. Imaginary (Z11) versus frequency Discuss the performance of your antenna 2) Figure A2 shows a microstrip antenna and impedance matching circuit. WI W2 W L Figure A2a: Microstrip Antenna with Impedance Matching w1 = 0.022.mm, 11 = 17.89mm, w2 = 2.95mm, L = 28mm, W = 40mm Simulate the microstrip antenna with matching circuit using AWR over the same frequency range as part A. You need to use FR 4 substrate with a dielectric constant of 4.5 and a thickness of 1.57mm. (i) Obtain graphical results a. S11 versus frequency b. Real(Z11) versus frequency c. Imaginary (Z11) versus frequency (!!) Discuss the performance of your antenna 3) Compare the performance of both antennas.
