Omnidirectional wrapped microstrip antenna for WLAN applications in laptop computers

An omnidirectional low profile microstrip antenna for WLAN applications in laptop computers is presented. By wrapping the patch antenna around the screen edge, very good omnidirectionality is achieved. The designed structure, fed by a microstrip inverted line, can be easily integrated inside the display plastic cover. An antenna prototype has been fabricated and tested. Good agreement has been obtained between simulations and experimental results. An adequate coverage of the whole 2.4 GHz ISM band has been achieved.
