摘要

Recent years have seen development of variety of dual band antennas specifically for next generation wireless communications systems that will require increased bandwidth and higher data rates. These dual band antennas find application in mobile terminals, such as cellular devices or portable laptops, Wi-Fi dongles. Antennas employed in such systems have certain requirements: High gain, stable and omnidirectional radiation pattern, reduced interference. This paper presents a compact dual band monopole antenna suitable for 2.4/5 GHz WLAN application. The antenna is fabricated on an FR4 substrate of size 20 × 30 × 0.8 mm~3 and consists of multiple meandering lines connected to the 50-Ohm microstrip feed signal line to generate the desired dual resonance frequencies. Two impedance bandwidths, for S11≤-10 dB, of 240 MHz and 2570 MHz have been obtained from simulation results which show that the required bandwidths of IEEE 802.11b/g (2.4-2.485 GHz) and IEEE 802.11a (5.15-5.825 GHz) can be completely covered by the proposed antenna. Prototype of the proposed antenna shows good agreement between simulated and measured results. Improved bandwidth and nearly omnidirectional radiation pattern of the proposed antenna at both resonance frequencies make it a viable choice for integration into modern portable devices. All simulations have been carried out using Ansoft's HFSS ver. 15.0.
