| Summary: | This paper presents a detailed investigation on
the phase agility of reflectarray antennas designed in the X-band
frequency range. A novel technique for the analysis of the
required reflection phase from individual reflectarray elements
to form a planar wavefront of the periodic aperture is presented.
Various slot configurations embedded in the patch elements of
reflectarrays are also proposed for the performance
improvement of reflectarray antennas. The feasibility of using
these slot configurations for frequency tunable reflectarrays and
designing periodic structure of slotted patch elements are also
demonstrated. The designed reflectarray antenna with
attainable frequency tunability of 1700MHz, demonstrated that
a maximum dynamic phase range of 320° and a volume
reduction of up to 24.36% are achieved at 10 GHz. |
