Review of Microstrip Patch Antenna for WLAN and WiMAX Application

In this rapid changing world in wireless communication, dual or multiband antenna has been playing a key role for wireless service requirements. Wireless local area network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) have been widely applied in mobile devices such as handheld computers and smart phones. These two techniques have been widely considered as a cost-effective, flexible, reliable and highspeed data connectivity solution, enabling user mobility. This paper presents a literature survey of dual band rectangular patch antenna for WLAN and WiMAX application with variety of substrate, feed techniques and slots. In this paper we also discuss the basics of microstrip antenna, various feeding techniques, design model and antenna parameters with their advantage and disadvantages.
