-A cavity backed coplanar waveguide to coplanar strip fed logarithmic uniplanar spiral antenna, which covers a 9 to 1 bandwidth with a return loss better than 10 dB from 0.4 to 3.8 GHz is presented. A wideband balun covering the frequency range of the antenna was developed.The constructed spiral antenna is very useful in a stepped frequency ground penetrating radar for humanitarian demining due to the very wide bandwidth, relatively small size, and being uniplanar. Successful detection of a small 5.4 cm non-metallic AP-mines in a pseudo minefield are presented.

“…The devices show narrow beam widths of ~35° FWHM in power, and reception angles of ±50°. Two dipole antennas coupled to coplanar strip waveguides, inspired by similar systems in microwave electronics [220], are coupled to a rectifying MOM diode. Due to the interference between the two antennas, the diode can be placed off-center and "see" off-normal angles.…”

Infrared photodetectors (IRPDs) have become important devices in various applications such as night vision, military missile tracking, medical imaging, industry defect imaging, environmental sensing, and exoplanet exploration. Mature semiconductor technologies such as mercury cadmium telluride and III-V material-based photodetectors have been dominating the industry. However, in the last few decades, significant funding and research has been focused to improve the performance of IRPDs such as lowering the fabrication cost, simplifying the fabrication processes, increasing the production yield, and increasing the operating temperature by making use of advances in nanofabrication and nanotechnology. We will first review the nanomaterial with suitable electronic and mechanical properties, such as two-dimensional material, graphene, transition metal dichalcogenides, and metal oxides. We compare these with more traditional lowdimensional material such as quantum well, quantum dot, quantum dot in well, semiconductor superlattice, nanowires, nanotube, and colloid quantum dot. We will also review the nanostructures used for enhanced lightmatter interaction to boost the IRPD sensitivity. These include nanostructured antireflection coatings, optical antennas, plasmonic, and metamaterials.

“…To facilitate numerical analysis, the metallization planes of slotline are assumed to be infinite to apply the available empirical formulas in [20], [24] for the various transmission-line parameters, including the characteristic impedance, effective dielectric constant, and attenuation constant. After obtaining the matrix of TSLO by (1) and (2), the input impedance seen from the end of ACPW can be given by (4) The cascade of all uniform and tapered transmission-line parts yields the complete equivalent circuit of the CPW-to-CPS transition, as shown in Fig. 1(b).…”

Abstract-The coplanar waveguide (CPW)-to-coplanar stripline (CPS) transition is analyzed theoretically and experimentally in this paper. To characterize this transition in the lower frequency band, a simple equivalent-circuit model that consists of uniform and nonuniform transmission lines is established. The elements of this model can all be obtained by the closed-form formulas; hence, this model is suitable for computer-aided-design application. This model is then applied to design and analyze the CPW-to-CPS transitions with various structure parameters. In the higher frequency band, the partially prizm-gridded finite-difference time-domain (FDTD) method is employed to take into account the bond-wire effect as well as the surface-wave leakage and space-wave radiation associated with the transition. In this study, results based on equivalent-circuit model, FDTD simulation, and measurement are compared. Good agreement among these results supports the usefulness of the proposed equivalent-circuit model and also validates the FDTD method. By using the equivalent-circuit model to optimize the transition configuration, the CPW-to-CPS transition with broad bandwidth and low insertion loss may be achieved.
