Compact metal-plate slotted WLAN-WIMAX antenna design with USB Wi-Fi adapter application
Compact metal-plate slotted WLAN-WIMAX antenna design with USB Wi-Fi adapter application
In this study, a compact antenna design, which operates in the 2.4, 5.2, and 5.8 GHz (WLAN) and 3.5and 5.5 GHz (WiMAX) frequency bands, has been implemented to be compatible with the 802.11.ac/n standards. Theproposed metal antenna is made of a copper plate of thickness 0.5 mm with a compact overall physical size of 20 mm× 30 mm. Although it is low-profile, it can work with high efficiency because it has a cheap planar metal structureand it does not contain any expensive dielectric material. The antenna is investigated in terms of S parameters, inputimpedance, efficiency, surface current distributions, and radiation pattern. The implemented antenna has been used ina USB WiFi adapter design for a desktop computer as an indoor WLAN application. The protector outer jacket of theWiFi adapter has been designed using a 3D printer, and the adapter card and driver are acquired commercially. As aresult, the produced WiFi adapter has been realized in a size of approximately 60% smaller than the other modules usingcommercially available monopole antennas on the market. The WiFi adapter provides IEEE 802.11.n/g/b standards andsupports USB 2.0. It has been observed that the speed measurement tests have been performed successfully and thatthe download-link and upload-link can reach 600 Mbps data rates. In addition, BPSK, QPSK, and 16QAM with OFDMmodulation techniques are used.
