The absorption spectrum of H-shaped fractal antenna with a gap at the center of the antenna and VOx layer formed on the gap for multi-band microbolometer was compared with that of it without the gap and VOx layer. At room temperature, simulation and measurement results for the characteristics of H-shaped fractal antenna with a gap and VOx layer have been showed that only one resonant wavelength has...
We have proposed microbolometer sensor coupled with H-shaped fractal antenna. Firstly we have designed the H-shaped fractal antenna by the approximate formula and finite element method (FEM) simulation. Then, we have fabricated microbolometer sensor and measured the characteristics of H-shaped fractal antenna. From the transmission measurement, we could successfully confirm the absorption peaks in...
A dual-band microbolometer coupled with an H-shaped fractal antenna, which can detect both infrared (IR) and THz waves simultaneously is proposed. Firstly, the H-shaped fractal antenna for 125 and 500 μm dual-bands is proposed by using the dipole antenna formula and finite element method (FEM) simulation. On the basis of simulation results, the H-shaped fractal antenna for the microbolometer is fabricated...
