Abstract
A leaky-wave antenna (LWA) realizes radiation of travelling wave along guiding structures. Periodic modulation is an effective approach to turn non-radiating modes into radiating modes. A high-efficient LWA based on spoof surface plasmon polaritons (SSPPs) loaded with parasitic patch array is proposed. Sinusoidal modulation is used for the radiation of SSPPs, while parasitic array mitigates the open stopband (OSB) effect. A prototype is fabricated and measured. The measured and simulated results agree well with each other. Such design shows wide angle coverage of 83° from backward to forward and stable gain distribution of about 12 dB within the whole operating band.
Highlights
Leaky-wave antennas (LWAs) was first introduced by Hansen in 1940, consisting of a slotted rectangular waveguide [1]
Spoof surface plasmon polaritons (SSPPs) are novel guiding modes excited on the surface of periodic metamaterial structures
Periodic surface waveguide is cascaded between two spoof surface plasmon polaritons (SSPPs) transmission lines to form well-performed LWA [15]
