To design an antenna for a specific frequency, first calculate the wavelength using λ=cf\lambda = \frac{c}{f}λ=fc, where ccc is the speed of light and fff is the frequency. For example, at 2.4 GHz, the wavelength is 12.5 cm. Then, select the appropriate antenna type (e.g., dipole or monopole), calculate the required length (e.g., 6.25 cm […]

Yagi antennas are directional, offering higher gain (up to 12 dB) and long-range communication, typically up to 50 kilometers at 2.4 GHz. In contrast, Omni antennas provide 360-degree coverage with lower gain (3-5 dB), ideal for short-range applications like Wi-Fi, covering up to 100 meters in open environments. Yagi antennas require precise alignment, while Omni
