This paper revisit and extend the interesting case of bounds on the Q-factor for a given
directivity for a small antenna of arbitrary shape. A higher directivity in a small antenna is …

Far-field shaping of small antennas is a challenge and the realizations of non-dipole
radiation of small to intermediate sized antennas are difficult. Here we examine the antenna …

Sub-wavelength antennas have become ubiquitous in essential devices, such as mobile
phones, sensors, Internet of things (IoT) and machine to machine (M2M) communication …
