Optical slot antennas and their applications to photonic devices
We present optical slot antennas and their applications to photonic devices. We show that metallic nanoslots have the properties of a slot antenna by measuring the transmission spectra and far-field radiation patterns and then prove that they can be ...

Textile UWB antennas for wireless body area networks [PDF]
A new ultrawideband (UWB) textile antenna designed for UWB wireless body area network (WBAN) applications is presented. Unlike previous textile antennas, these antennas offer a direct integration into clothing due to a very small thickness (0.5 mm) and ...

SAMBA: Superconducting antenna-coupled, multi-frequency, bolometric array [PDF]
We present a design for a multipixel, multiband (100 GHz, 200 GHz and 400 GHz) submillimeter instrument: SAMBA (Superconducting Antenna-coupled, Multi-frequency, Bolometric Array). SAMBA uses slot antenna coupled bolometers and microstrip filters.

Frequency Agile Slot Antenna Using Contactless Capacitive Loading
In this paper, a reconfigurable slot antenna capable of tuning a full octave in frequency from 2 GHz to 4 GHz is presented. The design is based on changing the capacitive loading of a slot antenna by physically displacing a metal plate connected to a ...

Comparison of an electrically-small planar antenna array with a conventional monopole array [PDF]
A new type of linear array is proposed which utilises annular slot antennas operating in the 'DC' mode. These conformal elements are electrically-small and have wire-monopole-like radiation patterns.
