Slot resonator with PBG layers

This paper shows the study and results of the three layers slot resonator using photonic band gap (PBG) substrate. The full wave transverse transmission line (TTL) method is used to calculate the complex resonant frequency, using double spectral variables. This method presents efficient and concise calculus in the determination of the structure parameters. Numerical results for the resonant frequency of three layer´s substrate slot antenna, for s and p polarization of PBG material, for different substrate thickness and resonator length are presented.
