Abstract

A new design of compact elliptical microstrip patch antenna is proposed for Ku-band applications. The proposed antenna consists of elliptical patch on RO3003 substrate followed by a thin foam substrate as dielectric followed by an infinite ground plane. In the ground plane, a square slot below the elliptical patch is cut. Theoretical reflection coefficient, gain and radiation characteristics of the antenna are discussed in this paper. The simulation results show return loss (S₁₁) better than 22.98dB at resonant frequency 14.6 GHz with the impedance bandwidth 33.56% or 3.95 GHz (12.9 GHz to 16.85 GHz) for voltage standing wave ratio (VSWR) <; 2 and 98.77% or 12.41 GHz (6.15 GHz to 18.15 GHz) for VSWR ≤ 2.3. The variation in gain is less than 1dB over the entire frequency range. The antenna presents nearly uniform radiation patterns across the frequency band with VSWR <;2. The overall size of proposed antenna is 50mm × 50mm × 3.162mm.
