Background /Objective: In the recent past Reactive Impedance Surface is used to increase the bandwidth of the patch antenna by antenna designers. The aim is to design a compact antenna using RIS for UMTS spectra.

Methods/Statistical analysis: RIS are effectively used in the design of the proposed antenna (which is made Compact) to increase bandwidth.

Findings: The proposed antenna has superior radiating features due to slots in its ground plane. It resonates at 2.18 GHz having a gain of 4.6 dB.

Applications: This antenna finds application in UMTS (SATCOM).
