Abstract
An electronic pet gate. The electronic pet gate includes a gate transmitter generating a barrier field and a gate receiver generating a deterrent stimulus in the presence of the barrier field. The gate transmitter includes a loop antenna in a low profile elongated sill and a barrier signal generator. The loop antenna transmits the barrier signal and has an elongated geometric shape configured to shape the radiated electromagnetic field into a truncated ellipsoid. The truncated ellipsoidal barrier field has significant field strength along the length of the low profile sill and minimal field strength along the sides of the low profile sill. The low profile sill is designed to securely rest on the floor to block access to an area restricted to a pet without being a substantial physical impediment or hazard to people passing over low profile sill.
