Abstract
This paper represents the numerical simulations of high gain inverted-F and loaded inverted-F antennas (IFA) for WLAN/Wi-Fi applications. The dimensions of the antennas are 16×34, 21×34 and 26×34 mm2 in case of IFA, slightly loaded IFA (SLIFA) and heavily loaded IFA (HLIFA) respectively. The antennas contain a very good peak gain of 7.89, 8.11 and 8.15 dBi with less than 1.2, 1.0 and 0.8 dBi gain variation within the -10 dB return loss bandwidth for IFA, SLIFA and HLIFA respectively. Moreover the proposed antennas can provide more than the required bandwidths for WLAN/Wi-Fi operations at 2.4 GHz (2.4~2.484 GHz) band. In addition, the proposed antennas have achievable return loss and radiation characteristics. Due to the compactness of the antennas, they are promising to be embedded within the different portable
devices employing WLAN/Wi-Fi applications.
