A 100 degree beamwidth ensures excellent hemispherical coverage. Symmetric coverage even in low elevation enhances accuracy. L1 Band Radiation Patterns Maxtena’s M1559CWT uses patented optimized microstrip technology which results in minimal dependence on frequency and features wide beamwidth, low axial ratio and radiation pattern symmetry across all desired frequencies in the L1 band.

Maxtena’s M1559CWT has minimal phase center variation over azimuth and elevation in the L1 band. Maxtena Inc. Rockville, MD 20855 1-877-629-8362 info@maxtena.com www.maxtena.com WIRELESS INNOVATIONS COMPANY Phase Center Variation vs. Azimuth at Theta=30˚ in L1 band. Phase Center Variation vs. Elevation in L1 band. Using GPS carrier phase to increase accuracy in GNSS applications has been proven reliable and has made mm-level accuracy possible. However, in resolving carrier phase ambiguity, it is necessary to make sure carrier phase is received and measured accurately and the effect of antenna and receiver on carrier phase is minimized. Maxtena’s M1559CWT has a flat response over its specified GNSS band and has minimal group delay variation over frequency. Maxtena’s M1559CWT antenna has a flat response over the L1 band, with less than 1 dB variation over it. The superior out-of-band rejection ensures minimal interference. Excellent Group Delay Variation Filtering and LNA Performance < 2 ns group delay variation over L1-band. Outstanding out-of-band rejection and less than 1dB fluctuation of in-band frequency response over L1-band.
