Millimeter-Wave Antenna With Adjustable Polarization

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...

Printed Wideband Antenna for Millimeter Wave Applications

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...

Millimeter Wave Multi-Beam-Switching Antenna

The paper introduces a high gain end-fire printed antenna operating at 14 GHz with a bandwidth of 2 GHz. The 3x3 antenna sub-array formed of this element is used to present its beam steering and multi-beam-switching capabilities for millimeter wave Massive MIMO antenna arrays of 5G networks. The co-existence of these two techniques in a Massive MIMO sub-array, aided by the use of a simple two v...
