Which of the following condition will lead to higher antenna efficiency?
23. Which of the following condition will lead to higher antenna efficiency?
- Decreasing radiation resistance often leads to increased antenna efficiency
- Increasing radiation resistance often leads to increased antenna efficiency
- Maintaining the equilibrium of radiation resistance often leads to increased antenna efficiency
- None of the above
Answer: B) Increasing radiation resistance often leads to increased antenna efficiency.
Explanation:
Radiation resistance is a measurement of the power wasted by the antenna as a result of energy radiation. Increasing radiation resistance often leads to increased antenna efficiency; this is because increased radiation resistance implies that a greater proportion of the input power is transformed into radiated energy, resulting in less power being lost.
