Electronics Letters (Impact Factor: 1.04). 01/2012; 48:68-U32. DOI: 10.1049/el.2011.3691

ABSTRACT A reconfigurable aperture-coupled reflectarray element offering a continuous tuning of the reflection phase is presented. A single varactor load is demonstrated to be sufficient for a full tuning range. Experimental validations are reported for the measured reflection phase of an X-band reflectarray element.

    ABSTRACT: Some of the most recent developments in reconfigurable reflectarrays using surface-mounted RF-MEMS, which have been developed at the Universidad Politécnica de Madrid, are summarized in this paper. The results include reconfigurable elements based on patches aperture-coupled to delay lines in two configurations: single elements and gathered elements which form subarrays with common phase control. The former include traditional aperture-coupled elements and a novel wideband reflectarray element which has been designed using two stacked patches. The latter are proposed as a low cost solution for reducing the number of electronic control devices as well as the manufacturing complexity of large reflectarrays. The main advantages and drawbacks of the grouping are evaluated in both pencil and shaped-beam antennas. In all the cases, the effects of the MEMS switches and their assembly circuitry are evaluated when they are used in a 2-bit phase shifter which can be extended to more bits, demonstrating that the proposed elements can be used efficiently in reconfigurable-beam reflectarrays.

    ABSTRACT: An electronically tunable reflectarray element is proposed in this work to design beam-steering antennas useful for radar applications. A reduced size reflectarray unit cell is properly synthesized in order to extend the antenna beam scanning capabilities within a wider angular region. The radiating structure is accurately optimized to provide a full phase tuning range by adopting a single varactor load as phase shifter element. A 0.46λ-reflectarray cell is designed at the frequency of 11.5 GHz, obtaining a phase agility of about 330°. The cell is successfully adopted for the design of a reconfigurable reflectarray. The antenna is numerically tested for different configurations of the varactors capacitance values, and good beam-steering performances are demonstrated within a wide angular range.

    ABSTRACT: A new approach is proposed for the study of a pla-nar Fabry-Perot antenna. A reliable description of the coupling between the cavity and the feeding waveguide is developed by taking into account for all the relevant eigenfunctions both in the waveguide and into the cavity. The cavity field is used to compute equivalent currents on radiating apertures, obtaining from them the radiated far field. The approach can be adopted for the analysis as well as for the synthesis of a large variety of cavity antennas.
