The technology of ridged-waveguide filters provides high midband frequencies as well as the suppression of spurious passbands up until very high frequencies. Due to the concept of these filters, broad bandwidths lead to reduced filter dimensions that are very difficult to fabricate. The interdigital arrangement of resonators guarantees a more reliable fabrication of these filters. The research was done in order to supply filters for the different frequency bands in the 5G communication standard.

In the paper we describe how the detection of living objects, such as people and animals, can be significantly improved. It is particularly important to detect people in dangerous environments to protect them. For such a detection task we use a radar system. Radar, because the detection also has to work at night and if it rains or snows, these are the situations when other systems, i.e. cameras, fail. Our experiments showed that many radar applications can benefit from our approach.

UAV-based antenna measurements are of particular interest for physically large antennas, where traditional antenna measurement techniques are not applicable. Precise position information is obtained by GNSS, where the receiving GNSS antenna is a critical system component. An additional antenna groundplane may be beneficial or even required, depending on the antenna design. Appropriate groundplane configurations improved the achievable position accuracy in the majority of investigated cases.

In near-field in situ measurements the antenna under test may not be accessed to use specifically tailored test signals. Instead there is a need to tackle modulated field signals where short-time measurement approaches offer a way to transform such fields using time-harmonic near- to far-field transformations. Short observation times make such approaches especially useful in measurement scenarios where unmanned aerial vehicles are used to move the field probe.

Short summary
In high-frequency technology, devices for filtering signals in the frequency domain are often based on resonant structures. As a result, the physical dimensions of a filter generally increase with decreasing frequency of operation. In this work, bandstop filters are built from special resonant elements with small physical dimensions to reduce the filter size. The small sizes result from the large permittivity of the used ceramic, increasing the electrical length of the resonant elements.

Near-field measurements are commonly performed in anechoic chambers which limits the flexibility and requires high precision equipment to achieve exact results. We investigate a simple near-field measurement setup that does not use a sophisticated positioning system nor does it operate in a controlled environment. Instead, the probe antenna is moved by an operator person while its position is measured by a laser tracker. Measurement results are shown to illustrate the performance of the system.

Short summary
Near-field far-field transformations are commonly performed for time-harmonic fields. Considering in-situ measurement scenarios with given transmission signals, time-varying aspects of modulated signals have to be taken into consideration. Two methods for the measurement of modulated fields are investigated and characterized, which work with a time-domain representation of the radiated fields and, at the same time, allow to employ the standard time-harmonic near-field far-field transformation.

Meta-sheets open up new opportunities in the design of radomes for microwave antennas. A meta-sheet typically consists of a periodic array of small resonators embedded in a thin dielectric layer. The smallness of unit cells and the large electrical size of microwave radomes significantly complicate full-wave numerical simulations as a very fine sampling over a large area is required. This paper proposes an efficient simulation approach, which combines Physical Optics and Finite Element methods.

Short summary
By analyzing the behavior of a self-mixing receiver, an appropriate model with a squre-law device can be obtained. This model is analyzed and a novel transmission technique with higher spectral efficiency is deduced by the formulation of the signal reconstruction problem as a phase retrival problem. Simulation results show the good performance of the proposed method.

This work investigates the errors, numerically and analytically, which occur due to the discretization of surveillance space in a multi-sensor radar system. The result of these investigations help to imprve the efficiency of the well-known compressed sensing algorithms. The improvement is critical for the cases where the signal processing algorithms must deliver the results within very short time intervals, e.g. 5 milliseconds or less.

Radar is well known for its utilization in the aeronautical and the automotive sector. Affordable systems have started conquering safety relevant applications as permanent monitoring units. New applications also entail new challenges. The paper investigates the effects of signal degrading sediments and assesses them. It is pointed out that liquid water has a particularly negative influence. In order to limit this disturbance factor, a methodology is presented to weaken its impact by up to 75 %.
