Abstract:
Design of a compact dual band (28/38 GHz)
antenna for sub mm-wave 5G application employing near field
resonant parasitic (NFRP) excitation is reported in this article.
Two differently sized electrically small stepped impedance
resonators (SIR), loaded beneath the substrate and above the
superstrate respectively, and parasitically excited by a
monopole printed on the top side of the substrate, constitute
the basic antenna element contributing to the dual band
performance at 28 and 38 GHz. This basic antenna element is
further deployed to realize a 2-element MIMO antenna
exhibiting excellent impedance and radiation characteristics
over both the bands. The design is currently under further
investigation and experimental results would be presented
during the conference. The proposed antenna exhibiting
impedance bandwidth of 3.5 GHz and 1.5 GHz centred at 28
GHz and 38 GHz respectively with satisfactorily low mutual
coupling and ECC ca
