A novel lumped LC resonator antenna with air-substrate for 5G mobile terminals
Abstract
The extending applications for mobile computing have experienced immense progress over
the previous decade. However, this has ultimately influenced the shortage of bandwidth. Therefore,
to fulfill the consumers’ demand, inexpensive antennas need to be uniquely designed for the next/fifth
generation (5G) frequency spectrum. Consequently, this paper presents a novel antenna composed of
inductors (L) or capacitors (C) on an air-substrate. Zinc (Zn) and copper (Cu) materials are utilized
to fabricate the lumped LC resonator prototype. The effects of antenna’s and substrate’s thickness on
resonant frequency or bandwidth have been studied. The finalized configuration engaged 1113 sq. mm
area and operated at 28 GHz with approximately 3 GHz bandwidth. At resonant frequency, the system
demonstrates peak gain and efficiency values of 10.6 dBi and 91%, respectively. The core objective of
this paper is to report an antenna featuring simple and economical design along with premium results
for 5G mobile terminals.
