Detail Information
Description :
This document provides a five-band+ GPS Antenna design; this simulation is for wireless LAN.
Application:
The application shall apply for antenna unit which shall be used for AVL or Fleet Management antenna systems. The combination of High Gain GPS antenna and a low profile covert GSM antenna is highly ideal for these applications that require durability, small in size, covert installation and rugged construction.
