In this paper, the authors have proposed microstrip phase antenna arrays for smart antenna applications designed at 2.7GHz frequency. The antenna array simulations are carried out by using IE3D software. The simulated antennas are fabricated using glass epoxy substrate with dielectric constant 4.4. The fabricated arrays are tested practically for the return losses, radiation patterns and gain measurements. Both the simulation and practical results are compared and found that they are in good agreement. Details of the antenna array design are presented and experimental results are discussed. Phased antenna arrays are useful for many types of applications such as traffic control and collision avoidance radars, smart base station antennas for WLAN and cellular communication.
