A fast and accurate analysis and synthesis technique for high-gain sub-wavelength 2-D Fabry-Perot leaky-wave antennas (LWA) consisting of two periodic metallodielectric arrays over a ground plane is presented. Full-wave method of moments (MoM) together with reciprocity is employed for the estimation of the near fields upon plane wave illumination and the extraction of the radiation patterns of the...
This paper presents an accurate analysis technique for designing broadband high-gain 2-D Fabry-Perot Leaky-Wave Antennas (LWA) consisting of two periodic metallodielectric arrays over a ground plane. Full-wave method of moments (MoM) is employed for the estimation of the near fields upon plane wave illumination and reciprocity is applied for the extraction of the radiation and directivity patterns...
This paper presents a fast and accurate analysis and synthesis technique for highly directive 2-D Fabry-Perot leaky-wave antennas (LWA) consisting of two periodic metallo-dielectric arrays over a ground plane. Full-wave method of moments (MoM) together with reciprocity is employed for the estimation of the near fields upon plane wave illumination and the radiation patterns of the LWA. Two antenna...
A new simple and rigorous analysis technique is presented to derive the complex dispersion characteristics of periodic 2-D Fabry-Pérot Leaky-Wave Antennas (LWA). In order to illustrate the basics of the method an example involving a 2-D periodic array acting as a partially reflecting surface (PRS) situated at half-wavelength distance from a ground plane is utilised. The analysis procedure is based...
We present simple and accurate analysis techniques to simulate and design high-gain Fabry-Perot resonant leaky-wave antennas (LWA). To control the radiation properties of these antennas, two metallodielectric periodic structures are used, one acting as a partially reflective surface (PRS) and a second acting as a high impedance surface (HIS). Full-wave method of moments (MoM) is employed for the estimation...
The analysis of sub-wavelength profile high-gain planar antennas employing two periodic surfaces (AMC and PRS) has been presented using periodic spectral-domain MoM. Three different cavity antenna designs consisting of a grounded 2-D infinite array of metal patches and a superimposed infinite PRS array have been proposed in order to validate the technique. The thickness of the cavity for the three...
