Robust, secure, low-power wireless communications and networking are needed to support
emerging applications in emergency and disaster response, robotics, autonomous vehicles …

A novel, highly miniaturized, lightweight antenna operating at the low-VHF band is
presented. Earlier studies on an extremely short HF monopole antenna consisting of two in …

Autonomous teams of unmanned ground and air vehicles rely on networking and distributed
processing to collaborate as they jointly localize, explore, map, and learn in sometimes …

Terrestrial signal loss prediction for the VHF band is limited to a few models. With perpetual
prominence in its application, understanding VHF signal variation in a different scenario …

The focus of this paper is to characterize near-ground wave propagation in the lower very
high frequency (VHF) band and to assess advantages that this frequency band offers for …

A low-power, low-frequency, ad hoc networking paradigm is considered for robust
communications among mobile agents in complex non-line-of-sight (NLOS) indoor and …

In this article, we investigate the problem of distributed coherent beamforming in wireless
networks where multiple distributed transmitters adjust the phases of their signals to form a …

A nonintrusive near-held measurement technique for 3-D radiation pattern and gain
characterization of antennas is presented. The method is of particular interest for low …

In this chapter, we present a literature survey of an emerging, cutting-edge, and
multidisciplinary field of research at the intersection of Robotics and Wireless Sensor …

This paper presents an extremely low-profile frequency-tunable composite antenna with
enhanced gain and an omnidirectional radiation pattern. The antenna is based on a recently …
