摘要：
In this paper, A novel stable gain printed log periodic dipole antenna (PLPDA) with two slotted dielectric substrates, based on the substrate integrated waveguide (SIW) technologies is proposed. This antenna consists of a traditional PLPDA fed by SIW, which reduces dielectric loss and conductor loss and two pieces of Rodgers5880 substrates with periodic slots, two pieces of Rodgers5880 substrates arc symmetrically loaded on PLPDA above and under respectively. The effects of slotted dielectric substrates were simulated. Simulated results show that antenna achieves a more stable gain than the traditional antenna over the frequency of 24.2-34.1GHz with reflection coefficient less than -10dB.
