Design and Performance Analysis of High Gain Narrow Band Patch Antenna Array at X-Band

The paper proposes a high gain narrow band array of rectangular microstrip patch antennas. Each element of the array is rectangular in shape. A high dielectric and low lossy material Rogers-3006 with dielectric constant 6.51, loss tangent of 0.002 and thickness 1 mm have been used as a substrate. 50 X microstrip line feed is used to exit the microstrip antenna. We cannot achieve high gain and directivity with single element so 8 x 1 patch antenna array designed to achieve high gain and directivity for intrusion detection application at precise operating frequency of X-Band. The patch array has been targeted for the application of "Intrusion Detection", where high gain, narrow bandwidth and higher directivity are needed.
