A Wide Band Pattern and Frequency Reconfigurable Microstrip Patch Antenna using Varactors for WLAN Applications
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 9
Abstract
Wireless communication systems are being used for a number of applications nowadays and for that, a number of antennas or a single antenna with multiple functional capabilities has become inevitable. This paper attempts to design a frequency as well as pattern reconfigurable microstrip patch antenna using electrical reconfiguration method. Three cases are being taken into account. The first case results in an operation at 5.2GHz and the remaining two cases offer operations at 5.2GHz and also at 2.4GHz. In the 5.2GHz band a ‘figure of 8’ E-plane pattern and an equal gain H-plane pattern are obtained in all the cases, whereas in the 2.4GHz band an equal gain E-plane pattern and 180º switchable H-plane patterns will be resulted according to the switching status. This antenna is an attractive candidate for Wireless Local Area Network (WLAN).
