The “Fragmented Aperture Antenna,” a computer-designed planar system, has already demonstrated a 33-to-1 bandwidth – well beyond the 10-to-1 ratio achieved by conventional designs. The researchers ...

The growing demands for wireless communications in tunnel environments are driven by requests for maintaining uninterrupted internet access for users in tunnels as well as wireless connections for ...

This paper proposes a numerically and experimentally validated printed wideband antenna with a planar geometry for Internet of Things (IoT) applications. This design tackles the challenges associated ...

The proposed high-precision fast direction-of-arrival estimation method for planar array includes two steps, and the expression of the result includes two items: 1) a 2-stage grid search approach over ...

Phased array technology is far from new. Phased-array antennas have been used for decades in a variety of military applications. Now, however, their use in 5G systems in the Band 2 frequency range is ...

Research Significance：With the rapid development of modern wireless systems such as radar and communications, there is an urgent need for the integrated development of multi-functional RF antennas.

For some applications single element antennas are unable to meet the gain or radiation pattern requirements. Combining several single antenna elements in an array can be a possible solution. This ...

Evolving communication systems are driving developments in the RF/microwave industry. The large umbrella of 5G focuses on supporting three main technologies: enhanced mobile broadband, which is the ...
