Compact U-shape radiating patch with rectangular ground planar monopole antenna

Abstract

A compact U-shape radiating patch with rectangular ground planar monopole antenna is proposed. Antenna is fabricated on FR4 substrate with permittivity 4.4 and loss tangent 0.02 with dimension 75(LR) × 48(WR) × 1.6(h) mm^3. Measured return loss is ≤ −10 dB for the entire impedance bandwidth (800–3500 MHz). In addition, different key parameters which affect the impedance bandwidth are analysed and results discussed. Moreover, antennas have acceptable gain flatness with good omnidirectional radiation patterns. Its ease of fabrication, compatibility with other electronic devices, and radiation pattern make it a competent candidate for global system of mobile (890–960 MHz), digital communication system (1700–1900 MHz) and Bluetooth (2.45 GHz) cellular communication applications.
