“…6 by means of the array simulator. For the design, we optimized the parameters of microstripline and slotline (no tapering) parameters as well as the shape and size of the virtual open circuit [48] to achieve the aforementioned design criteria. We remark that the rectangular shape was chosen for a better incorporation of the balun within the slot/FSS configuration (see Fig.…”

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.

“…Furthermore, rectangular waveguide is not a viable option as its bandwidth is too limited. Double-Y balun requires a large area for the slotline open circuit and via holes that cause severe parasitic effect at high frequency [6]. TSA with wedge-fed transition achieves a broadband performance [7], however, the pattern degradations are observed over almost the entire frequency range due to the interference from the wedge transition [8].…”

Two wideband tapered slot antennas are designed, fabricated, and tested. The first antenna, which is fabricated on a high dielectric constant substrate (e r 5 10.2), shows a measured return loss of better than 10 dB from 1.6 to 12.4 GHz (7.7:1 bandwidth), and an antenna gain varying from 3.6 to 7.8 dBi. The second antenna is built on a low dielectric constant substrate (e r 5 2.2), and demonstrates return loss of better than 10 dB from 1.8 to 15.2 GHz (8.4:1 bandwidth). The second antenna also has improved antenna gain, from 5 to 15.6 dBi, and is used to build a wideband 1 3 4 H-plane phased array with a total gain of 9-17 dBi and a beam steering angle of 6158 from 3 to 12 GHz.

“…The characteristics of the array have been analyzed by modeling the unit element of the infinite array using the numerical methods with periodic boundary conditions [1,2], or using the numerical waveguide simulators [3]. In these work, the active reflection coefficient (ARC) was characterized according to the beam scan angle.…”

coincident data. We measured temperature range from 50 to 240°C. CONCLUSIONSMeasuring for high-temperature and high-pressure with MFBG sensor had been described and its sensing principle was given laconically. The experiment results in this article demonstrated that the MFBG measure pressure maximum reached to 40 MPa and sensitivity was 0.0493 nm/MPa, and the temperature measure range from 50 to 240°C. To normal FBG, pressure sensitivity is 0.003 nm/MPa and temperature sensitivity is 0.0118 nm/°C near 1550 nm in wavelength. When compared with normal FBG, this structure improves characteristic of pressure and temperature about 19 times and 2 times, respectively. To MFBG1, its temperature change consistent with MFBG2 and pressure change very weakly, this can eliminate cross-sensitivity problem for simultaneity temperature and pressure measurement. Compared with epoxy resin bonded, MFBG temperature measure range enlarges one time. Thin layer of metal provides mechanical strength and eliminates out-gassing, at the same time increasing temperature range and heat conductivity of the fiber. The results from theory agrees well with that from the experiments. If mechanical pump was used, we can measure higher pressure. And at the same time, if we adjust material and size of the thin-wall copper cylinder, it can change measure range and sensitivity to adapt many environments such as oil-well and pipe laying.
