摘要

Design procedure of a high gain dual-band printed monopole antenna, resonating at 2.4 GHz and 5.5 GHz, is presented. The proposed design meets the specifications required by WI-FI, WIMAX and radio frequency identification (RFID) reader applications. Our design utilizes Rogers RT/Duroid 5880(tm) substrate, and the major radiation element is an annular circular patch shape. The design was improved by adding a face-to-face fork shape metal inside the annular circular patch. The antenna feed consists of a microstrip line and a slotted transformer section for matching purpose. A prototype of the proposed antenna was fabricated and the measurements of the return loss and antenna radiation pattern were performed. The comparison between the results obtained from the simulation and the measurements showed an excellent agreement.
