A 2-D closed-form model of multiferroic antennas in the GHz range is proposed. The model predicts the electrical and mode shape responses of film bulk acoustic resonators (FBARs) and solidly mounted ...

Wireless communications are rapidly advancing toward the next generation with much higher expectations for data rates, reliability, coverage, capacity, efficiency, connection, and latency, compared ...

In this paper, two K band antenna elements which consist of proposed semi-elliptical capacitive coupled and magnetic dipole patch antennas are designed and investigated for beam steering applications ...

All metal patch circularly polarized S-band antennas are being developed at NASA’s Jet Propulsion Laboratory for the Lunar Farside Seismic Suite (FSS). The antennas are proposed to be used as a ...

This paper reports the method of using near-field electric field data to detect array antenna feed faults based on region-based convolutional neural network (R-CNN). Four different models are trained ...

The inverted-F antenna with a parasitic branch (IFA&PB) is widely used in metal-bezel smartphones. Typically, the primary IFA branch is directly fed, while the parasitic branch is excited via ...

This paper presents a check-in system based on RFID technology. The adopted solution uses a multiplexer to interconnect several antennas using a single RFID reader. The flexibility is demonstrated ...

This paper explores the development of advanced electromagnetic antennas operating in the micro- and millimeter-wave spectra, essential for modern communication, radar, environmental monitoring, and ...

This paper demonstrates the use of additive manufacturing techniques through two examples of 5G internet of things (IoT) soil humidity sensors. A combination of inkjet-printing and 3D printing is used ...

This paper presents a complex antenna tile to be integrated in the fuselage of an aircraft for satellite applications in Ku-band. The different parts of the antenna and the interaction with the ...

The beamforming technologies of spaceborne multi-beam phased array antennas are first briefly discussed in this paper. Then, some successfully launched satellites using multi-beam phased array ...

Conventional resonant partially reflective surface (PRS) antennas suffer from narrow bandwidth and struggle to maintain a pencil-shaped beam at higher frequencies. This paper compares the near-field ...
