ABSTRACT:
A microstrip probe blade which has a ceramic body (20) with a microstrip (26) on one side and a metalized ground plane (30) on the other. A straight needle (32) having a tapered end and a spherical tip is attached to the microstrip axially and protrudes from the body parallel to the microstrip such that a high frequency signal may be conducted through the device with a minimum of electrical aberations. With this blade test, frequencies as high as 10 gigahertz may be achieved overcoming previous frequency limitations. The probe blade by virtue of the ground plane (30) wrapping around slightly to the microstrip side of the body (20) allows the addition of resistors (36) or chip capacitors (38) to minimize electrical spikes, transients, and unwanted opscillations to power supply frequencies.
