Millimeter Wave Antenna for Intelligent Transportation Systems Application

Integrated Design and Simulation for Millimeter-wave Antenna Systems

1 0-7803-6599-2/01/$10.00 © 2001 IEEE 2 Updated November 8, 2000 Abstract—Several instruments operating in the microwave and millimeter-wave bands are to be developed over the next several years at JPL or in conjunction with various other companies and laboratories. The design and development of these instruments requires an environment that can produce a microwave or millimeter-wave optics des...

Printed Wideband Antenna for Millimeter Wave Applications

A Millimeter-wave Slot-v Antenna

A new V-shaped slot antenna built on a dielectric substrate is presented. The antenna is a non-resonant, travelling-wave design, with a predicted impedance in the range from 50R t o €400. Calculations indicate that this antenna should have a gain of 15 dB with 3-dB beamwidths of loo in the H plane and 134' in the E plane. Pattern measurements at QOGHz support the theory. It should be possible t...

Injection Molded Millimeter-Wave Horn Array Antenna

This paper shows injection molded millimeter-wave horn array antenna for the 1-dimensional APAA(Active Phase Array Antenna). The antenna is composed of horn antennas, grooved circular waveguide polarizers, E-plane T-junctions, and E-plane bends employing dielectric waveguides. This structure makes it possible to manufacture a feed circuit and radiating elements as an integrated unit by using in...

Wideband Millimeter - Wave Cavity - Backed Bowtie Antenna

Although many directive antennas operating in a narrow band of millimeter (mm) waves were reported, e.g., antennas for 60GHz wireless local area network (WLAN), their wideband counterparts are still unpopular. Cavity-backed antennas (CBAs) are widely developed and reported in microwave frequency bands, but handful of literatures can be found about mm-wave CBAs in spite that their many propertie...
