Abstract
A broadband slot antenna array based on metasurface with gain stability is proposed for the 5 GHz wireless local area network (WLAN) band in this paper. Firstly, multi-mode resonant theory is used to widen the bandwidth of the slot antenna. Then, a non-uniform rhombic metasurface is placed above the slot antenna to expand the bandwidth of the antenna further while increasing the gain. Finally, nine rectangular patches are placed at the non-uniform rhombic metasurface. And the current in the high-frequency is amplified which leads to the maximum gain variation of only 1.7 dBi across the entire operating frequency range (4.7–7.7 GHz). To verify the design, a 2 × 2 antenna array is fabricated. The antenna array achieved a bandwidth of 47.6 % (4.8–7.8 GHz) and a maximum gain of 15.2 dBi within the operating band. The 1 dBi gain bandwidth is 2.1 GHz (4.7–6.8 GHz).
期刊介绍：
AEÜ is an international scientific journal which publishes both original works and invited tutorials. The journal''s scope covers all aspects of theory and design of circuits, systems and devices for electronics, signal processing, and communication, including:
signal and system theory, digital signal processing
network theory and circuit design
information theory, communication theory and techniques, modulation, source and channel coding
switching theory and techniques, communication protocols
optical communications
microwave theory and techniques, radar, sonar
antennas, wave propagation
AEÜ publishes full papers and letters with very short turn around time but a high standard review process. Review cycles are typically finished within twelve weeks by application of modern electronic communication facilities.
