DATASHEET Part No. 1002857 Product: EtherHelix GPS Antenna Part No. 1002857 EtherHelix Mission Critical GPS Antenna 1.575 GHz Circularly Polarized Supports: Aviation, GPS Navigation Systems, Fire & Rescue, Asset Tracking, Automotive, Security, Home Network application EtherHelix series of GPS Quad Helix Isolated Magnetic Dipole (IMD) antennas deliver on the key needs of device designers for higher functionality and performance in the worlds smallest Stand alone Circular polarized external and internal designs. These innovative antennas provide compelling advantages for GPS enabled cell phones, navigation equipment, and other mobile devices. Real-World Performance and Implementation Antennas may look alike on the outside, but the important difference is inside. Other antennas may contain simple PIFA or monopole patch designs that inter-act with their surroundings, complicating component layout or changing performance with use position. Ethertronics antennas utilize patented IMD technology to deliver a unique size and performance EtherHelix GPS Antenna combination. Quadhelix design Electrical Specifications Measured in Free space 1.575 GHz Frequency GPS - 1.575 GHz Polarization Right Hand CP (RHCP) Peak Gain (dBi) -3.0 -5 dB at Zenith KEY BENEFITS Smallest Effective Size Beam-width 120 degrees (Axial Ratio < 3dB) Ethertronics antennas require a Axial Ratio (dB) < 1.5 at zenith smaller keep-out area for surrounding components, leading Average Efficiency (%) 27 to a smaller effective size. VSWR Match 2.0:1 max High Performance Ethertronics high efficiency and Feed Point Impedance 50 ohms unbalanced simple design rules lower Power Handling 0.5 Watt CW development risk and speed time- to-market without sacrificing Mechanical Specifications & Ordering Part Number performance. Plus, high RF selectivity eliminates the cost and Ordering Part Number 1002857 space for band-pass circuitry.
