Design and Analysis of Single Feed Dual Band Stacked Patch Antenna for GPS Applications

摘要

An efficient double band with single feed GPS frequencies 1.22760 GHz (L2) and 1.57542 GHz (L1) such as Surveying, Mapping and Geo informatics. By trimming opposite sides of two different pair of square and isosceles corners of square patch in dielectric substrates, stacked patch antennae for double band operations are obtained. Both the upper and lower patches have 2 pairs of square and isosceles truncated corners each. The inculcation of corner truncation has achieved better return loss and gain at L1, L2 bands. A concise antenna is designed and simulated using IE3D simulation tool.
