Wideband Compact Dual Frequency Dipole Microstrip Patch
Antenna
A small size and very thinwideband dipole microstrip patch antenna for dual frequency operation is
designed and analysed in this paper. The dimension of the proposed antenna is 40×30×1.6 mm3
.The proposed
antenna is designed using a low cost and reliable FR4 substrate. This FR4 substrate material has a thickness of 1.6
mm, dielectric constant of 4.4 and loss tangent of 0.02. The proposed antennaresonates at 2.19 GHz and 2.5 GHz
frequencies with a -10 dB impedance bandwidth of 4.37 GHz, ranging from 1.8 GHz to 6.17 GHz.This shows the
proposed antenna bandwidth is increased to 200%. The VSWR of the proposed antenna is less than 2 for entire
operating frequency range. Radiation efficiency is above 70% at both of the resonance frequencies. A very low cross
polarization is found at all resonance frequencies. CST Microwave Studio is used to design and analyse the
proposed antenna.
