| Resumo: | In this paper, a dual-band patch antenna is developed for the Industrial, Scientific and Medical (ISM) bands of 2.4 GHz and 5.8 GHz with improved performance in terms of radiation pattern characteristics (antenna gain, front-to-back ratio and directivity) for both bands. For this purpose, a bandstop reflector based on Frequency Selective Surface (FSS) was designed and optimized. Simulation results show improved gain for the proposed structure for both frequency bands, with a gain of 7.54 dBi and 6.8 dBi at 2.4 GHz and 5.8 GHz, respectively. Measurement results showed a gain value of 7.46 dBi at 2.4 GHz. A bandwidth of 7% was obtained at the central frequency of 2.4 GHz (ranging from 2.37 to 2.56 GHz), while a bandwidth of 1.07 GHz (18.8% fractional bandwidth) was achieved at the frequency of 5.8 GHz. The measured experimental results were in agreement with those obtained by computational simulations and the satisfactory performance validate the proposed structure |
