Abstract
. A single-layer broadband endfire antenna with high-gain and stable beams based on the spoof surface plasmon polaritons (SSPPs) is proposed in this paper. The amplitude and phase of the surface wave are controlled by asymmetric protrusions on both sides. The anti-symmetric structure is added to balance the upper and lower electric fields while adjusting the impedance matching at the same time. Eventually, endfire radiation is generated with a stable beam to the free space within 5.25–7.94 GHz to form a relative bandwidth of 40.8%. The maximum achieved gain is 11.7 dBi at 7.1 GHz. The experimental results are basically consistent with the simulations. The antenna with high-gain, broadband and a stable beam can be effectively used in wireless communication systems.
期刊介绍：
Since 1992, the Radioengineering Journal has been publishing original scientific and engineering papers from the area of wireless communication and application of wireless technologies. The submitted papers are expected to deal with electromagnetics (antennas, propagation, microwaves), signals, circuits, optics and related fields.
Each issue of the Radioengineering Journal is started by a feature article. Feature articles are organized by members of the Editorial Board to present the latest development in the selected areas of radio engineering.
The Radioengineering Journal makes a maximum effort to publish submitted papers as quickly as possible. The first round of reviews should be completed within two months. Then, authors are expected to improve their manuscript within one month. If substantial changes are recommended and further reviews are requested by the reviewers, the publication time is prolonged.
