Design and Analysis of Microstrip Patch Antenna Array using Different Substrates for X-Band Applications

摘要

The paper proposes a high gain narrow band array of rectangular microstrip patches. Each element of the array is rectangular in shaped. FR-4 and Rogers-3006 material with dielectric constant 4.4 and 6.51, loss tangent of 0.002 and height 1mm have been used as substrates. The feeding is done using microstrip line feed. For the current scenario proposed design of 8×1 patch array antenna using ROGERS-3006, outputs better result as far as gain of the antenna is concerned in comparison with FR-4 in X-band application at precise frequency of 10 GHz. The patch array has been targeted for the application as sensor for "Intrusion Detection", where high gain, narrow bandwidth and higher directivity is needed, which are computed and compared in the proposed research.
