Abstract

This paper suggests a new solution for enhancing the immunity against the influence of size variation in ground on a boardintegrated GPS antenna. The original GPS antenna considered has the advantages of a simple design, low cost, and being directly integrated with the associated circuit board. Nevertheless, its performance depends on the ground of the circuit board. Without any special solution, the original antenna can withstand a ground size enlarged up to 122%, with respect to the minimal size required, for meeting the GPS specification. By using the suggested solution, the antenna can allow a ground size enlarged up to 269%. Thus, the improved antenna is more suitable for practical employment. In this investigation, various prototype antennas, with the suggested solution, were created and examined. Both simulated and measured results obtained demonstrate its promising performance stated above.
