With the arrival of the internet of things and the rise of wearable computing, electronics are
playing an increasingly important role in our everyday lives. Until recently, however, the rigid …

Both the radiation efficiency and bandwidth of electrically small antennas are dramatically
reduced as the size decreases. Fundamental limitations on the bandwidth of small antennas …

An approach for modeling antenna impedances and radiation fields in terms of fundamental
eigenmodes is presented. Our method utilizes the simple frequency behavior of the …

We introduce a systematic approach to the shape optimization of compact, single-aperture
MIMO antennas. Because the characteristic modes of a radiator represent its complete set of …

Acoustically driven antennas operating at resonant wavelengths up to 10 5 times smaller
than electrical antennas offer great potential for portable, low power communication systems …

Additive manufacturing paves new ways to the efficient exploration of the third space
dimension, providing advantages over conventional planar architectures. In particular …

New three‐dimensional (3D) printing techniques enable the integration of an antenna
directly onto the package of a small wireless sensor node. This volume‐filling approach …

Additive manufacturing of complex volumetric structures opened new frontiers in many
technological fields, turning previously inconceivable designs into a practical reality …

High‐gain directive antennas are used to support point‐to‐point long‐range wireless
communication channels. In typical designs, the array factor plays the key role, while …

A conformal microstrip antenna is highly integrated with the carrier profile, giving it the
advantage of reduced carrier space. However, the processing technology for fabricating an …
