An ultra-low profile reconfigurable multi-beam antenna based on impedance modulated metasurface
ABSTRACT A new ultra-low profile reconfigurable multi-beam antenna is proposed. It is based on impedance modulated metasurface fed with a one-divide-four electronically controllable feed network. By properly arranging the feed network, six beams at different azimuth planes are formed by controlling four diodes. The gain is enhanced through loading a cross metal strip in the middle of metasurface. The results indicate that the realized antenna has dimensions of 126 mm × 126 mm × 4 mm (equal to 2.1λ0 ×2.1λ0 ×0.067λ0, λ0, wavelength at 5 GHz). Its −10-dB bandwidth is larger than 30.0% (4.28 GHz − 5.79 GHz) when diodes I-V are turned on successively. And it can radiate beams pointing to (0°, 33°), (20°, 44°), (150°, 36°), (180°, 35°). Furthermore, the beams can be steered to (0°, 43°) and (180°, 43°) in case that diodes I&II or III&IV are switched on simultaneously.
期刊介绍：
Publishing eight times per year, Electromagnetics offers refereed papers that span the entire broad field of electromagnetics and serves as an exceptional reference source of permanent archival value. Included in this wide ranging scope of materials are developments in electromagnetic theory, high frequency techniques, antennas and randomes, arrays, numerical techniques, scattering and diffraction, materials, and printed circuits. The journal also serves as a forum for deliberations on innovations in the field. Additionally, special issues give more in-depth coverage to topics of immediate importance.
All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. Submissions can be made via email or postal mail.
