Thinner active elements create which combination of wavelength and frequency?

• A. Longer wavelength, Lower frequency
• B. Shorter wavelength, Higher frequency
• C. Longer wavelength, Higher frequency
• D. Shorter wavelength, Lower frequency

Answer: (B)

Thinner active elements resonate at higher frequencies, which means shorter wavelengths. The essential relationship is that wavelength and frequency trade off inversely for a given propagation speed: fλ = v. When you shrink the element, the resonant mode moves to a higher frequency, so the wavelength becomes shorter. In short, thinner elements produce a shorter wavelength and a higher frequency.
