Problem statement. Currently, the task of creating a domestic small-sized receiving antenna of the L1 and L2 frequency ranges for use as part of low-element densely packed antenna systems is urgent. L bands are used for terrestrial and satellite radio communications, satellite navigation systems, GSM mobile communications, radar, etc. The main difficulty lies in achieving small dimensions while maintaining key electrodynamic characteristics and, accordingly, low interference of antennas as part of a densely packed antenna system.

Goal. To consider the design and electrodynamic characteristics of a two-band compact antenna with sharp frequency selectivity. Describe the possible chemical composition of the substrate and its production technology.

Results. Information on the design, electrodynamic characteristics and frequency selectivity of a compact antenna designed to operate in the L1 and L2 frequency ranges. Basic data on the possible chemical composition of the ceramic substrate and its baking technology.

Practical significance. The use of the proposed antenna will make it possible to create densely packed two-band antenna systems from domestic resonators for GNSS digital antenna arrays.
