The emerging of Wireless Local Area Network (WLAN) now moving to demanding on higher data rate transmission. Wi-Fi system that is very popular with operating frequency at 2.4 GHz offered 11 Mbps and 54 Mbps data rates. However, WLAN with 802.11a standard and operating frequency at 5.2 Hz can offers data rate up to 54 Mbps with less interfences. The diversity method such as site diversity, polatization diversity, angle diversity and others can also improved the channel capacity for multi output (MIMO) wireless transmission system. So, this antenna will de designed at both 5.2GHz and 2.4GHz with dual polarizatiob radiation signal. The implematation of single port and single layer on this antenna design can reduce the complexity of the system integration.
