Design Of A Dual Band GSM Micro-Strip Patch Antenna

Abstract New design of obtaining a dual frequency bands antenna operate on the dual frequency bands of the Global System for Mobile Communications GSM Lower band 900 MHz Upper band 1.9 GHz with a single-feed square micro-strip antenna are proposed and experimentally studied. The proposed designs are based on the same patch dimensions configured with one rectangular slot in the form of cut inside the square patch antenna with different dimensions. The result of this work shows that the slot loaded into the square patch antennas offers further size reduction with multiband properties that can be used in GSM applications. Details of the design considerations of the proposed antenna are described and experimental results of the obtained dual-band GSM performance are presented and discussed.
