Nowadays, more and more technologies are implemented in vehicles to improve driver assistance in order to enlarge comfort and avoid accidents. Automotive radar systems have been gradually installed into vehicles with the growth of wireless technologies. Among the utilizations of automotive radar systems, survey around automobiles for the prevention of traffic accidents is one of the prospective...

Abstract Organic light emitting diode (OLED) technology continues to make strides, particularly in display technology, with costs decreasing and consumer demand growing. Advances are also seen OLED solid state lighting (SSL) though broad utilization of this is lagging. This situation has prompted extensive R&D achieve high-efficiency SSL devices at cost-effective fabrication. Here we review...

To meet the packaging requirements of terahertz (THz) communication systems, a microstrip line (MSL) to rectangular waveguide (RWG) transition is proposed in this paper. In transition, MSL connected corrugated substrate integrated (CSIW) by tapered for quasi-TEM TE10-like mode conversion on substrate, which requires no via holes or shaped dielectric, and easy process THz bands. Then, CSIW strai...

question I am frequently asked is, “Why do the antenna dimensions in the W1GHZ Microwave Antenna Book — Online not include the probe dimensions (for the transition from waveguide to coaxial transmission line)?” The answer is that the transition is part of the transmission line, not the antenna, and does not directly affect the performance of an antenna. The transition may be right at the antenn...

A broadband transition design between rectangular waveguide and GCPW is proposed and studied. The E-field of GCPW is designed to be gradually changed to that of waveguide via the simple tapered probes and metallic vias. The planar circuit of the transition is fabricated by low cost standard PCB process. The tolerance analysis for this transition is also given. A back-to-back transition prototyp...

Abstract—The paper presents integrated probe for direct coupling to the WR-10 waveguide with the use of metal filled vias on both sides of the microstrip line. Design and optimization of this novel microstripto-waveguide transition has been performed using 3-D finite element method based software HFSS (High Frequency Structure Simulator). A back-to-back transition has been fabricated and measur...
