Antenna Bandwidth Calculator
Antenna Bandwidth Calculator
This calculator helps determine the bandwidth of an antenna based on its center frequency and quality factor (Q). Bandwidth is a critical parameter in antenna design, indicating the range of frequencies over which the antenna can operate effectively.
Usage Guidance:
- Enter the center frequency of the antenna in MHz, GHz, or another consistent unit.
- Input the quality factor (Q), which represents the antenna's efficiency and selectivity.
- The calculator will compute the bandwidth using the formula: Bandwidth = Center Frequency / Q.
Example Calculation:
For an antenna with a center frequency of 100 MHz and a Q factor of 50:
- Bandwidth = 100 MHz / 50 = 2 MHz.
- This means the antenna can effectively operate between 99 MHz and 101 MHz.
Key Parameters:
| Parameter | Description |
| Center Frequency | The resonant frequency at which the antenna operates most efficiently. |
| Quality Factor (Q) | A dimensionless parameter indicating the antenna's selectivity and energy loss. |
| Bandwidth | The range of frequencies over which the antenna meets performance criteria. |
Applications:
- Designing antennas for wireless communication systems.
- Evaluating the performance of existing antennas.
- Optimizing antenna parameters for specific frequency ranges.
