For reliable communication with low-orbit satellites in portable wearable terminals, an antenna with a funnel-shaped radiation pattern is required, where the maximum radiation is concentrated in the sector of small and medium angles of the site, and reception from the zenith is suppressed.

Electrodynamic models of crossed antennas based on Tatarinov dipoles, butterfly dipoles and Nadenenko dipoles have been developed. For each of the proposed solutions, a stable funnel-shaped directional pattern was obtained with the width of the working sector at a location angle from 20° to 60° relative to the zenith.

The proposed antenna can be used in portable satellite communication terminals, emergency rescue beacons and personal trackers operating with low-orbit satellite groups in the UHF band. Its moderate size and weight make it possible to place the antenna as an external element or integrate it into the body of a portable device, and the funnel-shaped radiation pattern allows communication at an arbitrary position of the terminal relative to the satellite.
