Claim:
1. A method of making resistivity measurements of a formation from a wellbore being drilled, the method comprising: providing a resistivity measuring tool comprising: simultaneously transmitting electromagnetic energy into the formation from the first and second axial antennas, thereby inducing a voltage signal related to a formation parameter in the wire winding of the transverse antenna; combining and processing the signals generated due to the first and second axial transmitting antennas to (i) reduce or remove a formation resistivity anisotropy effect and thereby enhance a bed boundary effect, or (ii) reduce or remove the bed boundary effect and thereby enhance the formation resistivity anisotropy effect; measuring an angular position of the tool body relative to the wellbore with the sensor; and correlating the formation parameter with the measured angular position of the tool body.
