An SIW cavity is a useful tool to design an FSS which shows a rapid roll-off rate and insensitivity to polarizations and incident angles of electromagnetic waves. However, due to its high Q-factor, the FSS also shows narrow bandwidth which is undesir

A channel decomposition method is presented to evaluate the diversity performance of on-body UHF antenna systems. The novelty of this method amounts to separating the human body and propagation channel for independent estimation of each contribution.

We present an omnidirectional UHF body-worn antenna specifically designed for vests worn by law enforcement agencies. Typically, body-worn antennas suffer from pattern nulling that decreases communication reliability. The proposed antenna system cons
