This paper is the review of amateur-built high-directivity wire antennas, for Wireless Local Area Network (WLAN), operates at 2.4-GHz frequency range. Those antennas can be deployed for range extension and interference reduction, for example. Covered in this review are a biquad antenna with reflector, Yagi-Uda antenna, and helical antenna. The distinctive feature of these antennas is their ease of construction. The performance of those antennas is highly satisfactory, although they are not the commercial ones. Discussed in this review are their physical structures, directivity (Gain), input impedance, and polarization.
