N2 - Spoof surface plasmons polaritons (SSPPs) have the advantages of high field limit, low bending loss, single conductor configuration and low crosstalk, which is ideal transmission line for designing broadband high gain end-fire antenna. This paper presents a low-profile broadband high-gain conformal end-fire antenna, which is designed based on Spoof surface plasmon polaritons (SSPPs). The main radiator of the antenna is excited by the SSPP waveguide that is realized by etching a series of periodic corrugated grooves on the metal strip. This antenna uses a gradient corrugated groove as a transition section to convert the quasi-TEM mode to SSPP mode in the microstrip line, which can achieve the maximum impedance matching. And an extended triangular metal plane is placed on the bottom layer of the proposed antenna innovatively, to act as the reflector. And three printed metal strips are designed as the directors to improve the end-fire characteristics. The overall dimension of the proposed antenna is 1.62?×0.54?×0.014?, which shows low profile characteristics. The simulation results demonstrate that the realized gain of planar antenna is over 9.26dBi at the designed frequency 5.4GHz, and the return loss bandwidth (RLBW) is 16.1%. Half power lobe width reaches 56°. After antenna conforming to the cylindrical carrier, the end-fire performance agrees well with the planar antenna. Since the antenna is designed on a single-layer dielectric substrate, it has the advantages of high efficiency, good directivity, high gain, wide bandwidth, convenient production, and small size.
