چکیده
|
A tunable spoof surface plasmons antenna using sinusoidally modulated corrugated reactance surface based on a bulleye structure is proposed in this paper. the designed antenna is made of concentric metallic grooves etched on a metal plate, the depth of which is of sinusoidal periodic variation in the radial direction. this makes it possible that highly confined spoof surface plasmons along corrugated surface can be converted to radiation modes. the proposed bulleye antenna can work from 25.8 to 33 ghz and a bandwidth of 7.2 ghz and its main lobe can be directed at 30∘ from the vertical direction at 30 ghz. this antenna has a maximum gain of 15 db and its main lobe can scan from 14∘ to 58∘ by tuning the frequency from 28 to 32 ghz.
