This paper describes the building and testing of a 2.4 GHz antenna which can be used for WLAN as well as for other purposes. The antenna was built to have highest gain at 2.4 GHz although it can be used from frequency of 1.7 GHz up to 2.6 GHz. The paper also describes the calculation of the antenna parameters and dimensions as well as the measurements of its parameters. After the numerical modeling and building, the antenna was tested in the laboratory.The numerical modeling was performed with XFDTD software and the testing of the antenna was done at the Microwave Laboratory of Faculty of Electrical Engineering and Computing, Zagreb. The results showed that the highest antenna gain of 9.46 dB was obtained at 2.437 GHz, which is a frequency used for wireless internet. The antenna can be used on ships in the port as well as on the sea for boosting the range and increasing the received power level of a wireless internet signal.
