Proceedings of the 52nd European Microwave Conference Contactless Flanges and Rail System for mmW and THz Testing Lingyun Ren, Dhanraj Doshi, Yonghui Shu ERAVANT, USA {fn-lren, fn-ddoshi, yshu}-eravant.com Abstract ? In millimeter-wave (mmW) component engineering and manufacturing processes, it can be a constant struggle to achieve good calibration and measurement accuracy and repeatability. Fur

Proceedings of the 52nd European Microwave Conference Quasi-Monostatic Antenna Displacement in Radar Target Simulation Axel Diewald, Benjamin Nuss and Thomas Zwick Karlsruhe Institute of Technology, Karlsruhe, Germany Email: axel.diewald-kit.edu Abstract ? Radar target simulators (RTS) have recently drawn much attention in research and commercial development, as they are capable of performing ov

A new type of closed square ring decoupling structure is proposed in this letter, which can effectively reduce the coupling of antennas. The designed antenna is composed of two elliptical monopoles and a common ground loaded with a broadband parasitic decoupling structure. Considering the impedance matching, each antenna element is changed from the original rectangular microstrip feed to a tapered

An optically transparent ultra-wideband (UWB) Vivaldi antenna with a rectifier circuit is proposed in this paper. The proposed antenna is designed and fabricated on a soda-lime glass substrate with fluorine doped conductive oxide (FTO) as the conductive layer. A radial stub is used for better impedance matching and enhancing the impedance bandwidth of the antenna. It operates over a frequency rang

This paper explores an original study of bandpass (BP) negative group delay (NGD) robustness applied to the ring-stub passive circuit. The proof of concept (PoC) circuit is constituted by a ring associated with the open-end stub implemented in microstrip technology. An innovative experimental setup of a temperature room containing the NGD PoC connected to a vector network analyzer is described. Th

An effective method is proposed to excite the untilted edge slot antennas. In the proposed method, two T-shaped wires are placed at both sides of each untilted slot. Two legs of each T-shaped wire are connected to the waveguide walls, while the third leg is open. One of the T-shaped wires connects the upper broad wall of the waveguide to the narrow wall of the waveguide which contains the slots. S

A compact four-element ultra-wideband (UWB) multiple-input?multiple-output (MIMO) antenna with dual polarization and dual-notched capabilities was developed and fabricated. The MIMO antenna is composed of four orthogonally placed half-cutting UWB antenna elements. This orthogonal placement improves the isolation. Furthermore, an L-shaped slot and a continuous bending slot are etched to realize the
