Abstract :
WiFi USB dongles still draw some attention in the scope of wireless LAN device technologies, especially regarding the design of the radiator, which must be compact. The present work proposes a compact planar IFA-based antenna for a dualband USB WiFi dongle. The design of the antenna was numerically assisted using the antenna analysis software Empire XCcelTM. Experimental validation was achieved assembling and testing a prototype under practical conditions such as the influence of the dongle case, and the effect of plugging the USB stick in different positions alongside a typical laptop. Overall, the antenna complied well with the design constraints, notably regarding the good frequency stability of the impedance match.
