Therefore, we chose to select the values for the width of every
ground plane that implements an antenna that is self-resonant and
self-matched to 50Ω. The values for the PCB width of every
antenna configuration are listed in Table I. We note that the last
two antennas are well-tuned with widths close to or even higher
than quarter wavelength; the meander-lines, on the other hand,
operate well with narrow PCBs.
