Design, simulation, and fabrication of second, third, and forth order Hilbert antennas as ultra high frequency partial discharge sensor

摘要

This paper shows design, simulation, and fabrication of the second, third, and forth order Hilbert antennas as ultra-high frequency partial discharge sensor. This type of antennas use a complex geometry arranged from basic fractal geometry. The order of complex geometry depends on the number of iteration (The first iteration is order 1, the second iteration is order 2, etc.). Hilbert Antenna is an antenna that use Hilbert curve to arrange the complex geometry. Hilbert Antennas with 2nd, 3rd, and 4th order were simulated with HFSS 14 then were produced with double-sided PCB. Hilbert antenna were designed in different order, it is 2nd, 3rd, and 4th order for UHF range (300MHz until 3GHz) and in different size, it is size 1 (7¿¿7 cm2) and size 2 (10.5¿¿10.5 cm2).
