Abstract
A downhole electromagnetic modular system has two or more antenna modules incorporated into a drill string, each antenna module comprising an antenna sub and an antenna. The antenna modules may be spaced apart by one or more spacer modules, battery modules, spacer-battery modules, and/or downhole tools. The connected modules (and/or downhole tools) provide an electrical pathway throughout the modular system. An antenna module may have an inner connector formed on its antenna sub between the antenna of that antenna module and a retainer of that antenna sub. An antenna module may have two antenna groups located towards opposite ends of the antenna module and spaced apart by more than half the length of the antenna module. If an antenna group has more than one antenna, those antennas may be co-located or in proximity to one another. A probe may be held fixed by the retainer of the inner pin connector.
