The design and performance of low-profile,
multiple-feed metasurface antennas with different
numbers of patch cells and different substrate thicknesses
at a terahertz frequency are presented in this paper.
The utilized antenna designs consist of a periodic
array (N × M) metallic square-patch metasurface and a
planar feeding structure, which are both patterned on
an electrically thin, high-permittivity GaAs substrate.
The antenna gain increased in a linear fashion with an
increasing number of patch cells, which were directly fed
by the slit feedline. A 3-dB gain increment was observed
irrespective of the substrate thickness when the number
of patch cells was doubled. However, the 3-dB gain
bandwidth as well as the radiation efficiency changed
significantly with varying substrate thicknesses. The
described antenna structure offers useful characteristics
by means of a combination of different substrate
thicknesses and patch numbers. In addition, the proposed
antenna design features a number of benefits, including
a low profile, mechanical robustness, easy integration
into circuit boards, and excellent suitability for low-cost
mass production. |
