ABSTRACT:
In modern wireless communication system, demand of high bandwidth antennas
with low cost are increased. In proposed paper, these requirements
have been fully justified by using PBG based wideband antenna. Although,
metamaterial is one more option to build this idea, sometimes, negative permittivity
or negative permeability or both does not permit to allow easy fabrication
and maintaining low cost. An antenna with several periodic rods and
organic magnetic materials substrate made it possible to enhance the bandwidth
and think off using it for 5G communication systems. Proposed antenna
is designed and fabricated for frequency range of 40 GHz - 50 GHz, and 12
× 9 periodic rods with substrate having organic magnetic materials property.
Antenna is designed and analyzed using commercial simulation software CST
microwave studio (CST STUDIO SUITE 2014) and measured for return loss
and VSWR for fabricated design. Obtained results meet the requirement of
wider bandwidth of 1.5 - 2 GHz and return loss, ?35 dB, and directivity is 61
dBi with efficiency of 61%.
