MANET is a mobile ad hoc network in which nodes are move freely and perform the communication. In mobile ad hoc network, directional antenna plays a vital role. Directional antenna has many advantages such as increased transmission range, higher gain and reduced interference. Directional antenna uses a set of elements which has fixed beam nature and radiate the frequency in all directions and also at a specific angle. In this paper we analyze the performance of different directional antennas for different routing protocols such as AODV, LANMAR and RIP. The performance analysis is based on different metrics of the application layer such as average jitter, average end to end delay and the basis of physical layer metrics such as power consumed in transmit, receive and idle mode using QualNet 6.1.
