Antenna Engineer Interview Questions
91 antenna engineer interview questions shared by candidates
Some questions about basic antennas like patches and dipoles, smith chart operations and matching questions. Basic questions about antenna arrays.
What is antenna’s noise temperature
Explain your experience with designs in detail.
Software knowledge ( they didn't ask me since they were not convinced with my performance ) but they were about to conduct a demo of CST or HFSS
If high power amplifier on system board, how you going to test it?
Probability problem or series of numbers to complete. Simple antenna theory: reflection coefficient, dipole, PIFA, IFA, FRIIS equation, patch antenna... How can you cover the 700-900 MHz and 1700-1900 GHz band? (you need matching network) If you have two hours to make a dipole antenna how would you do? (if that's the job of an antenna engineer at Apple then I don't want the job). One of them asked me about the gain definition.... I had to explain him that the IEEE gain does not include the mismatch loss (only the realized gain does). Unit of directivity? Very insulting question when you have a PhD degree like also: what is the relationship between voltage current and capacitance. Some of the engineer where good and very nice. Sone others did not even care about the interview. One of them took me to the lunch barely spoke with me and realized when we came back that we were supposed to have the interview while having lunch (So I had only 5 mins of interview instead of 30mins).
how to make circular polarization with monopole antennas. explaining the Maxwell equations. how to measure the phase center.
What is Directivity? What is antenna gain? How much is path loss gain of 20dB? Explain what is a vector network signal analyzer? Explain to me what is regression testing? What's TRP and TIS and explain to me the difference between the two? What are the degrees measured at? What was your day-to-day like at your previous company? How do you setup your test procedures (at previous company)? What was your university major? Explain, why you chose it?
About my background and previous work I had done.
