    摘要: A patch antenna is disclosed having four ports for circular polarization that suppress the TM-02 mode, resulting in a radiation pattern that is symmetric. The axial ratio performance is consequently superior to that of two-port patch antennas. A four-port patch antenna includes a patch made of an electrically conductive material, a patch substrate coupled to the patch wherein the patch substrate is made of a dielectric material, a ground plane coupled to the patch substrate wherein the ground plane is made of an electrically conductive material having at least four slots formed therein, a feed substrate coupled to the ground plane wherein the feed substrate is made of a dielectric material, and a hybrid network coupled to the feed substrate that includes a right hand circularly polarized port, a left hand circularly polarized port, and two matched terminated ports.

    摘要: A stabilizer and method for use in a wellbore are disclosed. The apparatus can include a rotary body disposed about a tubular and configured to rotate and axially-translate with respect to the tubular. The apparatus can also include a first anti-rotation device disposed axially adjacent the rotary body and configured to resist rotation and axial translation with respect to the tubular. The rotary body can be configured to engage the first anti-rotation device and rotationally lock therewith. The apparatus can also include a biasing member configured to bias apart the rotary body and the first anti-rotation device.
