Sub-Millimeter-Wave Imaging Array at 500 GHz Based on 3-D Electromagnetic-Bandgap Material

Focal Plane Array-based Millimeter Wave Imaging Radiometer

The 4 GHz Bandwidth Millimeter - Wave Radar

The landmark construction of the Advanced Research Projects Agency (ARPA)–Lincoln C-band Observables Radar (ALCOR) at Kwajalein Atoll in 1970 sparked significant interest in the ballistic missile defense (BMD) and satellite-identification communities [1]. ALCOR's 50 cm range resolution using 512 MHz bandwidth data confirmed the viability of valuable new BMD discrimination techniques and provide...

Characteristics of Guided-wave Electromagnetic Bandgap Structure

1. Abstract The performances of the periodic surface structures (PSS) of different geometric shapes on the ground plane are studied. Simulated results with full wave electromagnetic analyses are in good agreement with those experimental data. The optimal structure of PSS bringing about the perturbation electromagnetic waves and power loss will be determined. The proposed wideband PBG microstrip...

Millimeter-wave Imaging Sensor

Electromagnetic waves in the millimeter-wave band have attractive characteristics. One of their features is the wider usable frequency band compared with waves in the microwave band or lower bands. Another feature of using the millimeter-wave band is the fact that it becomes possible to design smaller and lighter equipment that utilizes that band. So it is useful to adapt millimeter waves for s...

Electromagnetically-Coupled Millimeter-wave Antenna Array with Non-Uniform Distribution for 60 GHz ISM Applications

Abstract—In this article, the design of an electromagnetically-coupled millimeter-wave elliptical patch array antenna prepared to work in the 56–65 GHz (14.8%) frequency band is presented. The introduced antenna array is designed for low-loss, high-gain and low cross-polarization levels. The proposed antenna exhibits a measured gain of 8 dBi and good linear polarization across the desired frequ...
