Pixel Antenna Design for mm-Wave Wireless Communications to Achieve Wide Scanning
2024 18th European Conference on Antennas and Propagation (EuCAP)(2024)
Abstract
In this paper, we illustrate the feasibility of achieving extensive scan capabilities through the integration of a pixel antenna into a radiating matrix, designed for millimeter-wave communications. The antenna element is a combination of a capacitively coupled patch antenna and a partially reflective surface, that operates in the frequency range between 27 GHz and 29 GHz. With the integration of a linear matrix, we can achieve a scan range from
$-74^{\circ}$
to
$+74^{\circ}$
. In an 8
$\times 8$
matrix, the scan range extends from
$-63^{\circ}$
to
$+63^{\circ}$
in the
$\phi=0^{\circ}$
-plane and from
$-57^{\circ}$
to
$+57^{\circ}$
in the
$\phi=90^{\circ}$
-plane, with only a 3 dB scan loss. The planar matrix is arranged in a triangular grid, which significantly reduces mutual coupling with adjacent elements when compared to the regular grid.
