There is a scenario based question which is confusing for me Antenna had four rods each 15cm arranged as a plus sign. its brass shielding was cut and it had two 75 ohm coaxial cables in it. one 10 cm long was connected to rod A and C whereas other was 17.5cm long connected to rod B and D. On measurement you found good impedance match between antenna and cable. both the cable got combined at the other end into one input connector
- Find Center Frequency
- Predict polarization
- Plot radiation pattern.
Can you tell me how impedance matching works, do length matters and how can we know if antenna with given length is having a good match with coaxial cable with given length
