Abstract:
A resistivity logging tool includes a resistivity antenna and an antenna shield having a longitudinal slot segments interconnected to form an elongated slot with an elongated slot length that is longer than the length of the sleeve in which the slot segments are formed thereby enhancing electromagnetic wave strength propagated through the shield. Longitudinal slot segments may be interleaved to maximize the total number of elongated slots.
