Description
The MHA-1575A (formerly MWSL-1300) is a GPS L1 miniature dielectric-loaded antenna.
The MHA-1575A is a breakthrough GPS L1 dielectric-loaded antenna which uses MARUWA’s distinctive materials technology to provide unrivaled circularly-polarized gain from a uniquely small volume.
The dielectric core together with the flywheel effect of the advanced design provides excellent performance in the most tightly integrated applications. The MHA-1575A acts as its own filter, attenuating signals from common cellular and ISM frequencies by as much as 30dB.
Key Features
- Designed for installation with 1.5mm gap from antenna side to host PCB ground-plane
- Filters against interference from cellular and ISM bands
- Balanced design rejects common mode noise from ground plane
- Solder-pad installation to device PCB
Applications
- UAV/AUV
- Asset Tracking
- Hand-held Devices
- Traffic Enforcement
- Emergency Location
- Seismic Monitors/Measuring
- Wildlife Tracking
- Marine Tracking

Features of Sarantel Antennas
Helical Conformation is applied to MARUWA’s Dielectric Ceramic and our antenna has 4 features as follows.
- Wide Beam-width
- Jamming-Resistant
- Insusceptible to human body
- Compact Size
Wide Beam-width
Due to its wide beam-width, Sarantel Antennas can be attached at any angle.
Jamming Resistant
When receiving radio waves in the gap between buildings or trees, antenna receive signals from satellites and signals reflected by interference. In case of GPS, it calculates the location by using distance from the satellite. The actual signals from satellite and reflected signals are different in the route and if antenna recognizes both are correct signals, the result may become inaccurate.
As Sarantel Antennas are designed to receive the signals from satellite more strongly and less strongly to the reflected signals, they are jamming-resistant and calculate the location very precisely.
High Interference Resistance
Sarantel Antenna demonstrates high interference resistance. The chart on right hand side shows feature of “Return Loss”;
- Case 1: Free space only for antennas without the mobile device
- Case 2: Antenna placed in the mobile device and holding it by hand
- Case 3: Antenna placed in the mobile device and holding it by hand and close to human body
As Sarantel Antenna does not get interfered by human body, it shows high performance and feature.
Compact Size
The compact size is realized by using its high Q dielectric Ceramic.
