A Balanced Feed Triple Frequency Patch Loaded Printed Dipole Antenna for WiMAX/WLAN Applications

摘要

This paper presents a simple inexpensive balanced feed printed dipole antenna on FR-4 substrate with parasitic patches to enhance matching at the frequencies of interest. The antenna resonates in the 2.4GHz band, 3.5GHz band as well as the 5.2GHz band. The integrated balun ensures equal distribution of current to both dipole arms. The antenna is very simple in configuration having dimensions 70 × 58 × 1.52 mm^3.
