The vertical displacement of a columnar fluidic colloidal dispersion is examined as a frequency reconfigurable dielectric resonator antenna (DRA). The coaxial probe-fed structure has tunableâ€¦ (More)

A cavity model for a spherical inverted-F antenna (SIFA) is proposed using a custom curvilinear coordinate system. The coordinate transformation maps the spherical structure into an equivalentâ€¦ (More)

This work examines the integration of a spherical inverted-F antenna (SIFA) and a spherical buoy structure. The resulting multifunctional antenna system includes an inertial measurement unit (IMU),â€¦ (More)
