Superconducting planar-transmission-line resonators play an increasingly important role in applications such as astronomical detection and circuit quantum electrodynamics. When measuring the transmission response of array resonators, however, one often observes some spurious resonances besides intrinsic ones. In this letter, effect cavity accommodating a half-wavelength superconducting microstr...

The millimeter-wave front-end module for an automotive radar sensor is generally composed of an antenna placed on the front surface of the sensor head and a millimeter-wave circuit inside it. As the antenna for the radar sensor, several types of antennas, a slotted waveguide antenna, a triplate antenna, a dielectric lens antenna, a dielectric leaky wave antenna and a microstrip antenna, have be...

As the demand for low-cost electronic systems increases, increasing wiring density/reducing printed circuit board (PCB) layer count becomes inevitable. This reality limits the PCB routing layer options of high-speed input/output (I/O) signals, making it more difficult to meet the next-generation product’s performance targets. For example, using densely wired microstrip routing on a PCB helps re...

The basic shape structures are designed at frequency 2.4 GHz based on radiating structure 5 and 5.2 GHz based on radiating structure 3. The frequency bands that have been chosen are based on the IEEE standards. Then both structures are combined to achieve dual band resonant. The techniques that have been used are by designing the 3.5 shaped by using microstrip, planar and coplanar waveguide str...
