What is an Antenna Trap?

An antenna trap is an inductive component used in antenna design to isolate different sections of the antenna for different frequency bands. It allows a single antenna to operate efficiently on multiple frequencies by creating a high impedance at specific frequencies, effectively shortening or lengthening the antenna.

Example Calculation 1

Let's assume the following value:

Using the formula:

\[ L = \frac{31.8}{7} \approx 4.54 \text{ μH} \]

The Antenna Trap Inductance is approximately 4.54 μH.

Example Calculation 2

Let's assume the following value:

Using the formula:

\[ L = \frac{31.8}{14} \approx 2.27 \text{ μH} \]

The Antenna Trap Inductance is approximately 2.27 μH.
