Planar Waveguide Arrays for Millimeter Wave Systems

Design of high gain and high efficiency antennas is one of the key challenges in antenna engineering and especially in millimeter wave communication systems. Various types of planar waveguide arrays with series-fed traveling wave operation have been developed in Tokyo Tech with the special focus upon efficiency enhancement as well as reduction of fabrication cost. In this review, four kinds of ...

Dielectric Loaded Exponentially Tapered Slot Antenna Utilizing Substrate Integra- Ted Waveguide Technology for Millimeter Wave Applications

A novel compact dielectric loaded Exponentially Tapered Slot (ETS) antenna using Substrate Integrated Waveguide (SIW) technology is presented in this paper for Millimeter (Mm) wave wireless communication applications. The dielectric loaded ETS antenna and compact SIW feed are fabricated on a single substrate. The compact SIW feeding structure results in a considerable reduction in size and elim...

Millimeter-wave Slotted Waveguide Array Antenna Manufactured by Metal Injection Molding for Automotive Radar Systems

Development of A Compact and Low Profile ‎Cavity Backed Slot Antenna Using Microstrip ‎Gap Waveguide Technology

Proof of concept of a cavity backed slot antenna based on inverted microstrip gap ‎waveguide (IMGW) technology is presented. Since the antenna is operating based on the ‎first resonating mode of the cavity, it is more compact compared to the ordinary cavity ‎backed slot antennas in which the second cavity mode is used for radiation. Furthermore, ‎the proposed antenna element introduces lower lo...

Review of Antenna Technology for Millimeter Wave Automotive Sensors

Automotive sensors for the detection and discrimination of other vehicles on the road, obstacles, and boundaries use miniature radar systems and are heavily dependent in their performance on the antenna system. In this contribution, the requirements for such antenna systems are reviewed and the various options of antenna technology are discussed. In particular, prominent and presently employed,...
