This paper presents the design, signal processing, and field measurements of SPIDA, a
direction-finding antenna for the 2.4 GHz ISM band, intended for both communication and …

We study the benefits of electronically-switched directional (ESD) antennas in wireless
sensor networks (WSNs). ESD antennas have proved beneficial in cellular and ad-hoc …

Motivated by recent interest in directional antennas for WSNs, we propose a Four-Beam
Patch Antenna (FBPA) designed to meet the size, cost and complexity constraints of sensor …

Compared with omni‐directional antennas, directional antennas have many merits, such as
lower interference, better spatial reuse, longer transmission range, and improved network …

Directional antenna technologies have made significant advancements in the last decade.
These advances have opened the door to many exciting new design opportunities for …

Directional antennas have been shown to have the potential to provide dramatic increases
in throughput and reduction in delay, while simultaneously requiring lower transmit power …

We present the real-world evaluation of Spida, an electronically switched directional
antenna. Compared to most existing work in the field, Spida is practical as well as …

This paper considers the introduction of switched beam directional antennas in wireless
sensor networks. The paper compares the performance of an existing solution based on S …
