In the ad hoc networks, it consists of many sensor nodes, and each sensor node is equipped with five units. The transmission unit cares for the transmission and receiving of data through the antenna. In this paper, the microstrip patch and 1x2 array antennas are designed and fabricated. The results of simulated and measured results are compared at operating frequency 5.4GHz. The results show the enhancement in the bandwidth and low VSWR which shows the maximum radiation of power. The array antenna can be operated for the wideband with better reflection coefficient, gain, bandwidth, and VSWR and radiation pattern. This smart antenna is self-efficient to configure with multiple high directivity beam to save the power, range and use reuse of channels. Such smart antennas are used for the ad-hoc network, Wi-Fi, UWB, and high-speed LTE applications.
