摘要: A system, according to an embodiment of the present invention, comprises a coupler, remote antenna, and handheld GPS receiver. The antenna has microstrip RHCP receiving element low noise amplifier (LNA) powered by coupler over interconnect cable. slotline driver circuit. re-radiates satellite signals received with In typical installation, such as car, user holds receiver while in front seat. mounts windshield cable runs mounted on roof car. can then re-radiate effectively even when two are separated much six feet. shielding metal car is thereby avoided problem that prevent operation
