🔍 Key Concepts

• Resonant frequency of an antenna as an electrical circuit (like an LC circuit) • How inductance (L) and capacitance (C) each affect resonant frequency in basic electronics: ( f = \frac{1}{2\pi\sqrt{LC}} ) • Effect of adding a pure resistance (R) on resonance vs. on bandwidth and losses

💭 Think About

• Think about which component(s) actually appear in the resonance formula and how changing their values shifts the resonant frequency up or down. • Consider what happens when you add that component in series with the antenna: does it effectively increase total inductance, total capacitance, or just add loss? • Ask yourself: does changing the transmitter’s output frequency alter the antenna’s natural resonant frequency, or only how well the transmitter is matched to the antenna?

✅ Before You Answer

• Remember that resonant frequency depends on L and C, not directly on R or the transmitter’s setting. • Check which series component would increase the effective L or C seen by the antenna, thereby lowering the resonant frequency. • Verify which option only damps or wastes power (affects efficiency and bandwidth) without significantly shifting the resonant frequency.
