“…1) is comprised of crossed slot elements whose dimensions are altered by using radio-frequency (RF) switches such as microelectromechanical systems (MEMS) [9], [10], [13], optoelectronic switches [14], or PIN diodes [8], [15]. The interleaved two-band configuration of the array elements is considered in order to reduce the array size significantly [16]- [18]. This configuration choice also provides broad-band array performance without grating lobes by choosing the element spacings sufficiently small [19]- [21].…”

A novel dual-band reconfigurable aperture (RECAP) design is introduced for operation over a two-octave bandwidth. The proposed RECAP consists of interleaved crossed-slot elements for dual-polarized and broad-band array operation without grating lobes. The dimensions of the array elements can be reconfigured by using radio-frequency switches such as microelectromechanical systems or PIN diodes. The array elements along with the switches are integrated into the top layer of a multilayered composite structure consisting of passive, resistively loaded frequency selective surface (FSS) elements that form a broad-band ground plane system. Excitation is provided through a broad-band balanced/matched feed, and reconfiguration allows for broad-band operation using the same FSS substrate. Besides the FSS substrate, shorting pins can be employed within the cavity to enhance gain performance. Significant analysis and understanding of the FSS/slot array configuration is presented along with measurements that should serve as a reference in future developments of these layered arrays.Index Terms-Antenna isolation, broad-band balun, broaband substrate, frequency selective surface, mode suppression, reconfigurable aperture, slot antenna array.

A new phased array antenna of wide bandwidth and good beam scanning angle has been developed using a low cost multiline phase shifter controlled by a piezoelectric transducer (PET) and a stripline fed Vivaldi antenna array. The multiline progressive PET phase shifter has a low perturbation loss of less than 2 dB and a total loss of less than 4 dB up to 40 GHz with a maximum phase shift of 480 . The proposed phased array antenna consists of four E-or H-plane Vivaldi antennas, a PET phase shifter, and a power divider. The phased array shows a wide beam scanning capability of 27 over a wide bandwidth from 8 to 26.5 GHz covering X, Ku, and K bands.Index Terms-Phased array, phase shifter, piezoelectric transducer (PET), wideband phased array.
