Abstract： Portable telemetry devices, due to their exceptional mobility, ease of transportation, and the capability for temporary augmentation, provide robust supplementary support for telemetry tasks. Among the components of portable telemetry devices, the quality of antenna performance directly impacts the overall system′s performance and decisively determines the range of applications it can be used for.Most existing portable telemetry devices are equipped with directional antennas, which have a narrow beamwidth. This poses significant limitations when these systems are added to special scenarios such as mobile platforms at sea. To address this, an array of multiple antennas is proposed, utilizing multi-antenna signal synthesis techniques to design a phased-array antenna that offers hemispherical coverage.Simulated testing and practical application validation demonstrate that this antenna achieves coverage from 0° to 360° in azimuth and from 0° to 90° in elevation. The gain fluctuates less than 2 dB within the elevation range of 0° to 90°, and it exhibits a gain greater than 8 dBi at low elevations. This outstanding performance makes it highly suitable for receiving telemetry signals from high-speed mobile targets at sea, significantly broadening the application scope and practical effectiveness of portable telemetry devices.
