19. Which of the following type of antenna has a directivity of 0 dB?
- Horn antenna
- General antenna
- Patch antenna
- Isotropic antenna
Answer: D) Isotropic antenna
Explanation:
An isotropic antenna has a directivity of 0 decibels isotropic (dBi). An isotropic antenna is a reference point for measuring the performance and directivity of other real-world antennas; we can also say that this sort of antenna is completely idealized.
