GeMiC 2019 is a scientific conference aiming to bring together academic and industrial researchers from Germany and from abroad, to discuss research progress and prospects in the area of microwave and millimeter-wave theory and techniques.
Phased array systems have made major steps forward with the development of manymajor radar and communications systems. Due to many recent advances, including MMIC,photonics, anddigital beamforming, phased array systems and technology continue to progress rapidly.Current and futuredevelopments of ground -based, sea-based, airborne, and space -based phased array radar,communications,and other electronic systems will be discussed at this international symposium.
This is a conference with a focus on wireless components, applications, and systems that impact both our current and future life style. The conference's main niche is to bring together technologists, circuit designers, system designers, and entrepreneurs at a single event. It was and is the place where these worlds meet, where new processes and systems can be benchmarked against the needs of circuit designers at the bleeding edge of RF systems, where today's design compromises can trigger tomorrow's advanced technologies. Where dreams can become a reality. RWS is the cornerstone conference for Radio Wireless Week.
The interest of Commission B is fields and waves, encompassing theory, analysis, computation, experiments, validation and applications. Areas of emphasis are 1) Time-domain and frequency-domain phenomena, 2) Scattering and diffraction, 3) General propagation including waves in specialised media, 4) Guided waves, 5) Antennas and radiation, and 6) Inverse scattering and imaging.The Commission fosters the creation, development, and refinement of analytical, numerical, and measurement techniques to understand these phenomena. It encourages innovation and seeks to apply interdisciplinary concepts and methods.
IEEE Antennas and Wireless Propagation Letters (AWP Letters) will be devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation.

A K band Dual-Polarized monopulse microstrip patch antenna array has been designed. The 4*4 rectangular patchs and the cross shaped sum-difference network both are optimized by CST. Each polarized antenna array, sum- difference and the feed network are placed on the same layer respectively, which makes this antenna array smaller and compacter. H-shaped apertures are used to promote port-to-port isolation ...

Sharp-directional antenna arrays, excited with electromagnetic waves travelling along a transmission line, are widely used in practice as alternatives to sharp-directional reflector, lens and horn antennas, especially in cases when it is necessary to control the main lobe pattern direction, i.e. as phased antenna arrays. Lately, in connexion with the development of space telecommunication technologies, the interest in non- phased ...

A K band Dual-Polarized monopulse microstrip patch antenna array has been designed. The 4*4 rectangular patchs and the cross shaped sum-difference network both are optimized by CST. Each polarized antenna array, sum- difference and the feed network are placed on the same layer respectively, which makes this antenna array smaller and compacter. H-shaped apertures are used to promote port-to-port isolation result as -25 dB and facilitate the complex microstrip network.
Sharp-directional antenna arrays, excited with electromagnetic waves travelling along a transmission line, are widely used in practice as alternatives to sharp-directional reflector, lens and horn antennas, especially in cases when it is necessary to control the main lobe pattern direction, i.e. as phased antenna arrays. Lately, in connexion with the development of space telecommunication technologies, the interest in non- phased arrays has been revived. The basic reason for this is the smaller volume of such arrays in comparison with aperture antennas having the same characteristics. Moreover, using microstrip and slot radiators allows sufficiently simply realization of plane or conformal antennas. This paper carries out investigations of the angle antenna arrays difference patterns and demonstrates that their slope can be larger than for linear arrays with the same number of radiators and band features. This is determined from the band properties of their sum patterns.
A 20 GHz active receive slot array has been developed for operation in the downlink frequency band of NASA's Advanced Communication Technology Satellite (ACTS) for the ACTS Mobile Terminal (AMT) project. The AMT is used to demonstrate voice and data communication between a mobile terminal and a fixed terminal via the ACTS satellite. The active antenna consists of an array of fourteen linear series-fed-type microstrip slot arrays, fourteen packaged monolithic microwave integrated circuit (MMIC) low noise amplifier (LNA) submodules connected at each subarray output, a 14-way Wilkinson-type power divider, and a final additional LNA submodule used as a driver amplifier. The active receive array was designed to achieve the receive sensitivity requirement by placing the LNAs as close as possible to the antenna subarrays, minimizing the losses that occur in front of the amplifiers. The additional driver amplifier further minimizes the system G/T sensitivity to losses that follow the antenna.<<ETX>>
A circularly polarized feed array for a spacecraft reflector antenna is described that was constructed by using linearly polarized microstrip elements. The array has seven subarrays which form a single cluster as part of a large overlapping cluster reflector feed array. Each of the seven subarrays consists of four linearly polarized microstrip elements. The array achieved a better than 0.8-dB axial ratio at the array pattern peak and better then 3 dB antenna gain to 20 degrees from the peak, across a 7.5% frequency bandwidth. A teardrop-shaped feed probe was used to achieve wideband input impedance matching for the relatively thick microstrip substrate. The low impedance and axial ratio bandwidths were achieved using a relatively thick honeycomb substrate with the impedance-matching feed probes.<<ETX>>
The authors present a novel method for the analytical determination of the amplitude distribution providing the low sidelobe pattern of conformal array antennas. The proposed projection method considers both the nonuniform element density and element patterns on the aperture. Numerical results are given as well as results of experimental verification for an X-band, half-spherical array with 60 rectangular microstrip antennas.<<ETX>>
A low-profile, wide-band antenna array with side-lobe control is presented. The array consists of tapered slot elements fed by a planar microstrip power divider. The power divider incorporates two- dimensional amplitude tapering through a series of unequal T- junctions which gives side-lobe levels of -20 dBi. The number of elements in the array is 8 by 8, and it operates from 12 GHz- 18 GHz. Measured results show that the array has high gain and low side- lobe levels over the entire operating frequency. The methodology involved in designing this array is useful and can be extended to create arrays for radar applications as well as for communication systems.
