“…The transmitting/receiving antenna system plays a key-role in all the ground penetrating radar applications [16,17]. In order to introduce the approach at hand, let us assume that the antenna system is deployed under a multi-monostatic configuration (i.e., the location of the transmitting antenna coincides with the measurement point) and moves over a scanning plane at z = 0 while radiating a monochromatic wave.…”

Abstract-This paper presents a reconstruction approach which exploits the field detected by a holographic radar in order to localize and geometrically qualify a set of scattering objects. In particular, thanks to the adoption of the Kirchhoff Approximation, the problem is formulated as a linear inverse one wherein the unknown function is the characteristic function accounting for the support (location and geometry) of the target(s). The reconstruction performances of the approach are investigated through an accurate numerical analysis, and an experimental validation is also performed with the aim of testing the effectiveness and the practical relevance of the proposed method.

Abstract-The design and full-wave analysis of piezoelectric microneedle antenna sensors for minimally invasive near-field detection of cancer-related anomalies of the skin is presented. To this end, an accurate locally conformal finite-difference time-domain procedure is adopted. In this way, an insightful understanding of the physical processes affecting the characteristics of the considered class of devices is achieved. This is important to improve the structure reliability, so optimizing the design cycle. In this regard, a suitable sensor layout is described, and discussed in detail. The major benefit of the proposed system stems from the potential for obtaining a superior performance in terms of input impedance matching and efficiency, in combination with an electronically tunable steering property of the near-field radiation intensity which can be profitably used to enhance the illumination and, hence, the localization of possible malignant lesions in the host medium. By using the detailed modeling approach, an extensive parametric study is carried out to analyze the effect produced on the sensor response by variations of the complex permittivity of the skin due to the presence of anomalous cells, and thus useful heuristic discrimination formulas for the evaluation of the exposure level to cancer risk are derived.

“…The tunability property is also known as reconfigurability characteristic. Reconfigurable devices such as antennas [1][2][3][4][5][6][7][8][9][10][11][12][13][14], filters [15][16][17][18][19], impedance tuners [20][21][22][23], phase shifters [24,25] and amplifiers [26][27][28][29] have been used in recent years, considerably. The pattern, polarization, bandwidth and resonant frequency are fixed radiation parameters of the conventionally used antennas.…”

Abstract-A novel multi-state RF MEMS switch for microstrip antenna applications is presented. The proposed switch exhibits seven different states of operation, has a very simple DC biasing mechanism, and can be integrated with antenna structure. Based on these properties, this switch may find its usage in multifunction reconfigurable antennas. To exhibit this application, it is employed in the reconfiguration mechanism of a U-slotted antenna. In different states of the switch, the antenna resonates at different frequencies. All the standard frequency bands of the wireless communication services with some additional frequency bands is covered with this reconfigurable U-slotted antenna. Moreover, the proposed antenna structure is a cost-effective solution since it comprises a commonly used FR4 substrate. The switch is integrated with antenna structure on the same substrate. A prototype of the designed antenna was fabricated and tested for performance verification of the proposed switch and antenna.
