In this paper, a high gain narrow band array of rectangular microstrip patch antennae is proposed. Every array element is rectangular in shape. 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. Microstrip lines are used as feed lines to substrate. The proposed design of 8x1 patch array antenna using ROGERS-3006, gives better results in comparison with FR-4 in microwave application. The operating frequency is considered as 10 GHz. The patch array has been targeted for the application as sensor, where high gain, narrow bandwidth and higher directivity is needed, which are simulated and compared in the proposed research.
