Abstract
A compact log-periodic antenna based on Spoof surface plasmon polaritons(SSPPs) is proposed in this work. The antenna consists of three part: the microstrip line, the SSPPs conversion part, and radiation part. The SSPPs structure generates surface waves, which are eventually radiated by dipoles acting as radiators. The SSPPs mode has high field limitations, and tightly restrain the signal in the groove structure of SSPPs to ensure the efficient transmission of the signal and reduce the transmission loss. The simulation results show that the voltage standing wave ratio(VSWR) of the antenna is lower than 2 and the gain is higher than 6.1 dB in the frequency range of 7.3-10.6 GHz. The proposed antenna has a good performance of low profile, compact structure, which is of great value in wireless communication systems.
