“…Now, various planar microwave SSPP transmission lines (TLs) [12] have been designed using PCB technology from C-to K-band, for example, single-conductor SSPP structures [13] and hybrid structures (SIW/SSPP or half-mode SIW/SSPP) [14,15]. By employing the novel characteristics of SSPP such as highly confined field, non-linear dispersion, and deep subwavelength, many functional microwave devices have been designed, such as filters [16,17], dividers/couplers [18,19], and various types of antennas [20][21][22][23].…”

In this study, a novel frequency beam-scanning (FBS) antenna based on composite substrate integrated waveguide/spoof surface plasmon polariton (SIW/SSPP) waveguide is proposed. The composite SIW/SSPP slow-wave waveguide is designed by embedding a series of periodic subwavelength H-shaped grooves on the top surface of the SIW. Its transmission characteristics own both the features from SIW and SSPP, and can be flexibly mansplained by tuning the key structural parameters. To convert the propagating composite slow-wave mode into the radiation mode effectively, a new flexible digital modulation method with staggered metallic vias is proposed and used. The presented beam-scanning antenna has a simple feeding structure, a single dielectric layer, and a compact volume of 0.75 � 8.55 � 0.015 λ 0 3 . A prototype of the antenna is fabricated and tested to verify its performance. The experimental results demonstrate that the proposed antenna can realise a continuous beam-scanning angle of 49°in an operating bandwidth of 8.7-9.2 GHz with a high frequency-scanning sensitivity (FSS) of 9.8 °/100 MHz −1 . Moreover, the measured results indicate that the antenna has high peak gain with an average level of 12.7 dBi, high radiation efficiency with an average level of 87%, and stable unidirectional radiation pattern in the working band.

This letter proposes an end‐fire Vivaldi antenna based on spoof surface plasmon polaritons (SPPs). SPP is generated by a periodic corrugated metal–insulator–metal (CMIM) waveguide on which the odd mode of the SPP is propagated and is rarely used in the design of antenna transmission lines. Gradient corrugations and slotlines form the transitional part to achieve momentum matching and impedance matching between the microstrip feed line and plasma waveguide. In addition, one parasitic patch is introduced in flare aperture to improve the performance of the radiation. Both the simulation and measured results are carried out and match well with the theoretical design. This antenna generates end‐fire radiation beams within 4‐9 GHz frequency range (S11 < –10 dB). Measured results show that the realized gain is higher than 8.87 dB and the 3 dB beam width is stable between 31 and 36° over the operation frequency.

“…For example, various plasmonic transmission lines (TLs) have been developed [2,[15][16], and their characteristics also have been thoroughly analyzed by others, these TLs based on SSPPs structures can be used to enhance the EM field confinement, reduce the crosstalk and improve the transmission efficiency. The low loss and high efficiency properties of SSPPs TLs inspire researchers to present different wireless devices, such as antennas [17][18][19][20][21][22], filters, power dividers [27][28][29] and couplers [30][31].…”

An Ultra-Thin and Compact Band-Pass Filter Based on Spoof Surface Plasmon Polaritons

In this work, we report an ultra-thin and compact SSPPs-based waveguide band-pass filter with metals etched on the top surface of substrate, and the side and bottom surfaces of substrate also are covered with metals. The size of this filter is 1.07λ 0 ×0.32λ 0 ×0.02λ 0 (where λ 0 is the wavelength at center frequency). This proposed filter can inherit the merits of rectangular waveguide and SSPPs structure, and its lower cutoff frequency can be tuned by the width of rectangular waveguide, while the upper cutoff frequency can be tuned by the length of complementary comb-like structure. Gradient groove depths are also used to form a smooth transition from rectangular waveguide to SSPPs structure, realizing a good momentum match. The dispersion curves and electric field distributions have been thoroughly investigated to reveal the SSPP-based waveguide filter mechanism. A prototype is fabricated and measured. Both simulations and measurements validate that the band-pass filter proposed in this work has high-efficiency and low-loss transmission properties.
