A series of S-band radar scans of grape vines conducted over the growing season is presented. Despite covering the time frame from early development of grape berries to harvest, there is minimal observable change in the radar imagery. This observation along with theory of scattering demonstrate that microwave glare from shoots is the dominant feature in the imagery.

We present significant improvements on in particular our transmitting applicator and its performance. This is a crucial component of our system for direct detection of internal inhomogeneities such as breast tumors and brain hemorrhages by a special transmitting applicator and specially polarized receiving applicators. The operating frequency is about 1 GHz. The transmitting applicator is unique by no need to contact the object under study (OUS) and does not generate any surface waves at it. The primary field has properties behaving as from a magnetic monopole. The overall system allows direct detection without a need for phase measurements, which provides the possibility of using a simple microwave generator and simple rectification and position registration of the received signals. The receiving 3D contacting applicator contains a high-permittivity ceramic and is resonant in order to provide the desired field polarization sensitivity. The desired system properties are achieved by optimized use of the orthogonality properties of the primary magnetic, induced electric, and diffracted electric fields.

The radiation characteristics of Chebyshev function-based power weighted linear array antennas influenced by elements configuration are investigated in terms of width of main lobe (WML) and sidelobe level (SLL). The investigation is also performed using a theoretical approach focused on synthesizing process. The use of Chebyshev function as weighting coefficient for linear array antennas with number of elements less than 10 shows that the variation of array-elements-number (N) with a constant inter-elements-spacing (d) can improve WML and provide notable impacts to SLL. While the variation of inter-elements-spacing (d) with a constant array-elements-number (N) yields to the WML improvement without significant effect on SLL. The theoretical approach is then validated by the experimentation with the error rate in SLL and WML of 1.68% and 3 %, respectively.

Antenna radiation pattern measurement has been a challenge to many researchers, especially when the size of the antenna is large due to the requirement of a large anechoic chamber. Furthermore, a quick measurement process is required when many radiation patterns need to be measured. In this paper, a measuring system to measure a large interleaved linear array antenna of a total length of 1.35 meters operating at C band frequency was constructed. The measuring system was constructed with an azimuth range capable of nearly ±180° and able to measure radiation patterns of an array with linear or circular polarization. Typical measurement speed to provide a sample of 1028 measurements points is 16 seconds, with 0.116° resolution for 120° azimuth range without a positioner component.

Presented is a numerical study of the impact of the antenna pattern sampling resolution on the accuracy of Over-The-Air (OTA) throughput measurements. More specifically, a Line-Of-Sight (Random-LOS) testing scenario is addressed. The communication throughput is evaluated as the Probability of Detection (PoD) of a single bitstream based on the ideal digital threshold receiver model. The maximum deviation of throughput efficiency is computed as a function of the azimuthal sampling resolution for various generic antenna gain patterns. The coefficient of variation of the antenna gain pattern is introduced to evaluate the impact of the azimuthal sampling. The presented approach can be used to define the sampling resolution of the throughput performance of a device under test in Random-LOS OTA.

In this research study a Microwave-based Tomography (MWT) system is developed as a low cost system which consists of a microcomputer-based data acquisition module that obtains data from a PocketVNA and a mechanical system based on stepper motors which are used to control the angular positions of the Vivaldi antennas along a circular path around the observed object. The stepper motors are driven through motor drivers and an Arduino board. The used Vivaldi antennas can be operated as microwave transceivers from frequency of 1.5 GHz to 9 GHz, while the PocketVNA is used to measure the transmission and reflection coefficients (S11and S12), magnitude and phase of the microwave that have a frequency range of 500 kHz to 4 GHz. Measurements in this study were carried out in the frequency range of 3–3.78 GHz with an increase in frequency of every 0.5 GHz, and measurements were executed 5 times at each angle position, while the antenna position was shifted every a 5°. The test object used was in the form of an octagonal iron metal and cylindrical metal also nylon or polyethylene. The images of the reconstruction process based on Born approximation algorithm significantly illustrates the shape and cross section of the test object.

In this paper, a metal-frame-based dual-band 4-antenna multi-input and multi-output (MIMO) system operating at both 3.3-3.6 GHz and 4.8-5.0 GHz bands for the fifth-generation (5G) mobile applications is proposed. Each antenna element consists of a rectangular feeding branch, an L-shaped slot and an L-shaped coupling branch. The slot and coupling branch are excited by the feeding branch to generate the low (3.45 GHz) and high (4.8 GHz) resonant frequencies. In particular, the L-shaped slot is set on the metal frame of the mobile handsets, which makes the antenna element and metal housing well integrated. A simplified antenna prototype is fabricated and measured. The simulation and measurement results, such as S-parameter, efficiency, envelope correlation coefficient (ECC) and 3D radiation pattern are presented. And the simulation and measurement results can have good agreement.

This work illustrates the benefit of subtracted beam antenna we presented earlier for a sensor system in fruit pre-harvesting. The angular resolution pattern of a receiving antenna that shows how far the unwanted object (fruit) can be eliminated from the desired target (fruit under test) is proposed. The link budget for the beam subtracted antenna is also calculated to indicate the transmitting power for ensuring the receiving power for a normal sensitivity of the sensor. This calculation shows that the beam subtracted antenna can be employed in pre-harvesting of fruits.

In recent years, the requirements for high power transient electromagnetic field measurement have gradually increased. The calibration is the most critical part in accurate measurement. Therefore, the need for high-accuracy calibration of high power transient electromagnetic field sensors, including amplitude calibration and frequency bandwidth calibration, has become increasingly urgent. However, IEEE Std 1309-2013 does not contain a specific calibration method for high power transient electromagnetic field sensors. In this paper, by analyzing the TEM cell and the monocone TEM cell, combined with the advantages of these two standard electromagnetic field generating devices, these two TEM cells are selected as the calibration devices for the transient electromagnetic field sensor. Unfortunately, the size of TEM cell, constrained with the calibration accuracy, decreases its frequency bandwidth. And the low frequency of monocone is unavailable due to its narrow time window. As a viable solution, the TEM cell is used for amplitude calibration, meanwhile the monocone TEM cell is used for frequency bandwidth calibration. Moreover, a practical and operational calibration process is proposed in this paper. The process includes the obtainment of the calibration coefficient $K$ in the amplitude calibration, as well as the determination method of the sensor's upper frequency in the bandwidth calibration.

This paper proposes a secondary radar for detection of hidden pedestrians. A transponder carried by a pedestrian responds to a radio-wave transmitted from a car. The distance between the transponder and the car can be measured by using a phase detection scheme, where the frequency detected radio-wave is doubled at the receiver.
