A novel ultra-wideband waveguide-to-microstrip transition for millimeter-wave applications

Broadband Millimeter-wave Microstrip Line to Waveguide Transition

Millimeter-wave antennas have been developed for applications of broadband high-speed wireless communication systems and automotive radar systems in these days. Microstrip antennas (MSA) are more advantageous than other millimeter-wave antennas at the viewpoints of low-profile and low-cost. The antenna is connected to the backed RF circuits through the waveguide in the millimeter-wave module as...

A Novel Multilayer Microstrip Antenna for Ultra Wideband Applications

As wireless communication applications require more and more bandwidth, the demand for wideband antennas increases as well. For instance, the ultra wideband radio (UWB) utilizes the frequency band of 3.1-10.6 GHz .In this paper we introduce a new multilayer microstrip antenna for ultra wideband applications. In order to achieve suitable bandwidth, the antenna size is fine for mobile application...

Broadband Transition from Microstrip Line to Waveguide Using a Radial Probe and Extended GND Planes for Millimeter-Wave Applications

A broadband microstrip line-to-waveguide (MSL-to-WG) transition is developed for E-band applications. In order to achieve a sufficient and broadband coupling between the microstrip line (MSL) and waveguide (WG), a radial electric probe at the end of the MSL and extended ground (GND) planes on the dielectric substrate are proposed. Results are compared against a simple transition (S-Tr) with a s...

Millimeter-Wave Microstrip Line to Waveguide Transition Fabricated on a Single Layer Dielectric Substrate

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...
