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.
