Antenna Toolkit — Simulation Quiz

Total number of questions - 4

Simulate the following cases using Antenna Toolkit before starting the quiz. For each case, create a new design and rename it.
Case A : Inset fed patch antenna as shown in workshop.

Case B : Inset fed patch antenna as shown in workshop with inset distance of 1mm.

Case C : Planar inverted F antenna with center frequency of 2.4 GHz and Duroid as substrate.

Case D : Planar inverted F antenna with center frequency of 2.4 GHz and FR-4 epoxy as substrate.

1 / 7

What happens to the resonance frequency of the inverted F antenna you have created, if the permittivity of the substrate material is increased? (Compare the results of case C and case D)

Shifts to higher value

Shifts to lower value

Remains same

2 / 7

In case C, what is the frequency range for which the S11 parameter is below -20 dB?

3.40 GHz to 3.45 GHz

2.40 GHz to 2.45 GHz

1.40 GHz to 1.45 GHz

4.40 GHz to 4.45 GHz

3 / 7

In case C, what is the input impedance value at 2.4 GHz frequency? (Select the best option)

0.2 - 1.1i Ohm

1.1 - 0.2i Ohm

1.1 + 0.2i Ohm

0.2 + 1.1i Ohm

4 / 7
