Reconfigurable Antenna Design Based on Fresnel Zone Plate
2021 IEEE 4th International Conference on Electronics Technology (ICET), 2021The rapid development of wireless devices now requires antennas to be highly flexible more than ever. In this work, we demonstrate a reconfigurable antenna with beam steering based on Fresnel Zone Plate (FZP). The FZP-based antenna is implemented on a metasurface mounted with microwave PIN diodes.

Fresnel zone plate antennas at millimeter wavelengths
International Journal of Infrared and Millimeter Waves, 1991The performance characteristics of Fresnel zone plates are described with emphasis on applications at millimeter wavelengths. Recent results are included along with a summary from numerous earlier investigations. Parameters described include design information, efficiency, bandwidth, focal characteristics, off-axis performance, axial intensity ...

Infrared antennas coupled to lithographic Fresnel zone plate lenses
Applied Optics, 2004Several designs for Fresnel zone plate lenses (FZPLs) to be used in conjunction with antenna-coupled infrared detectors have been fabricated and tested. The designs comprise square and circular FZPLs with different numbers of Fresnel zones working in transmissive or reflective modes designed to focus infrared energy on a square-spiral antenna connected

Millimeter-wave Fresnel zone plate antennas
SPIE Proceedings, 1994Fresnel zone plate antennas have seen extensive research in recent years. Both transmission and reflection types have been analyzed and tested, and found to give excellent performance. Parameters such as far-field patterns, gain, efficiency, frequency dependence, aberrations, scan capability, focal region properties, and off-axis performance have been ...

Beam control in Fresnel zone plate antennas
Proceedings. The 9th Russian-Korean International Symposium on Science and Technology, 2005. KORUS 2005., 2006The problem of synthesizing the structure of the diffractive antenna does not have a unique solution and the beampattern can be corrected by choosing the free parameters or/and optical scheme. All this can be applied to create directivity pattern of unconventional form, for example, conical beampattern.

Conical Double-Dielectric Fresnel Zone Lens and Antenna
IEEE Microwave and Wireless Components Letters, 2007A conical double-dielectric phase-reversal Fresnel-zone plate (FZP) lens is introduced. We present the lens design equations as functions of cone opening angle. As an example, the phase-reversal lens has been applied to four millimeter-wave antennas with different lens opening semi-angles: 45deg, 60deg, and 75deg (conical lenses) and 90deg (plane lens).

Variety of cylindrical Fresnel zone plate antennas
IEEE Antennas and Propagation Society International Symposium. 1999 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.99CH37010), 2003Variations on the half-open cylindrical Fresnel zone plate (CFZP) antenna have been studied in this paper. Starting from the Ji and Fujita's (1996) CFZP antenna model with about 5 dB gain we designed antennas with much higher gain: up to 8.5 dB for the same size quarter-wave antenna, and up to 11 dB for the same height, but 3 times larger in diameter ...

Multilayer phase correcting fresnel zone plate reflector antennas
International Journal of Satellite Communications, 1993AbstractOwing to its flat nature and light weight etc., the Fresnel zone plate antenna is becoming very attractive for such applications as DBS reception and receive‐only VSAT. The disadvantages of low efficiency and high sidelobes of the simple and the phase reversing zone plates can be improved by using phase correcting techniques.

Off-axis-fed fresnel zone plate antenna
17th International Conference on Infrared and Millimeter Waves, 2017Phase-correcting zone plates may be used with off-axis feeds. For angles up to about 20A‚° off-set, the performance is well-behaved, with minor degradation. The design is given for a transmission type and an equivalent reflecting version having a 17A‚° feed offset.
