No, this is not an “L-band”, GNSS antenna ... BUT it demonstrates the shrinking size.

NEW Molex 206513 Antenna for 2.4 GHz, 3x3x4 mm in size.
Less than $1.00 for quantity 1, both Mouser and Digi-Key now stocking.

Molex’s 206513 series is a 2.4 GHz embedded ceramic antenna with high efficiency over 55% on all frequency bands. This miniature SMT ceramic component requires a very small (4 mm x 4 mm) keep-out area and is designed to be mounted directly at the corner of the main device PCB. It has a frequency range of 2.4 GHz - 2.5 GHz, return loss of <-6 dB, and peak gain (max) 3.6 dBi. It features an omnidirectional radiation pattern.
