DGS based Planar Inverted F Antenna for Multiband Applications

Abstract

As Long Term Evaluation systems have more benefits when compared to other network systems, it became more popular. Integrating a lower band with a higher by considering space as a constraint became a challenge for designers. A simple PIFA (Planar Inverted F Antenna) with DGS(Defective Ground structure) is suggested inmultiple band applications. The proposed antenna is designed using the CST Microwave Suite 2017. The design is for substrate having εrof 4.4(FR-4), (tan δ ) 0.02 as loss tangent with a thickness of 1.53mm is preferred for designing of this antenna and is etched directly upon the substrate.
