摘要： Interconnection apparatus providing a right angle H-plane bend in grounded coplanar waveguide (GCPW) transmission line media. Respective first and second GCPW lines include a dielectric substrate, on which is formed on a bottom surface a bottom conductive ground plane, and on a top surface is formed a center conductor strip sandwiched between first and second top ground plane strips. The two GCPW lines are disposed orthogonally, forming a corner junction at which corresponding bottom and top ground planes, and the center conductor strips, of the lines are electrically connected. The gaps between corresponding top ground plane strips and the center conductor strips have regions of increased gap width at the corner junction to compensate for the capacitance resulting from the junction.

摘要： A microstrip probe that can be inserted into the mouth or radiating portion of a thick flared notch or open ridged waveguide radiator element within an array antenna aperture and coupled to the TEM feed circuit transition of that element. The probe can then be used to extract performance diagnostic data of the circuitry behind the array aperture without removing the aperture itself. The probe bypasses the radiating portion of the array element and the effects of mutual coupling associated with the array. The probe is a printed circuit board whose thickness matches the gap dimension of the flared notch feed circuit transition line at its feed launch point. A coaxial connector at one end provides a connection to a microstrip line formed on the circuit board. The ground plane of the microstrip narrows to transform the microstrip line into a broadside coupled strip transmission line, which runs to the insertion end of the probe. The strips are shorted together at the insertion end. A slot is formed at the insertion end which is one quarter wavelength in length to encourage coupling from the feed circuit into the probe.

摘要： Low frequency radiating elements are embedded in a flared notch array. The flared notch array forms a series of parallel troughs in which absorptive loads are placed to reduce the antenna radar cross section. The low frequency radiating elements are embedded in the array transverse to the troughs at or below the level of the absorptive loads, and excite several troughs. The absorptive load material is absorptive in the operating band of the flared notch array, but appears as a relatively low loss dielectric at the lower frequencies of operation of the low frequency radiating elements. The low frequency radiating elements can perform Identify Friend or Foe functions in the UHF and L-band regions of the spectrum, while the flared notch array operates at X-band.

摘要： A length of strip transmission line uses two symmetrically spaced center conductors between two groundplanes. These conductive strips produce an even-mode electric field between the two groundplanes when excited in-phase and an odd-mode electric field when excited in anti-phase relationship. For the latter case, the phase velocity of the odd-mode is significantly affected by the electric field in the gap region between the conducting strips. By varying the relative dielectric constant of a material located in the gap region, e.g., by means of a voltage-controllable dielectric such as barium-titanate compositions, the phase velocity and, hence, the phase shift of an RF signal propagating through the strip transmission medium can be controlled.

摘要翻译： 一段带状传输线在两个接地面之间使用两个对称间隔的中心导体。 当激发同相时，这些导电条在两个接地平面之间产生均匀模式的电场，当以反相位激发时，产生奇模态电场。 对于后一种情况，奇数模式的相位速度显着地受到导电条之间的间隙区域中的电场的影响。 通过改变位于间隙区域中的材料的相对介电常数，例如通过诸如钛酸钡组合物的电压可控电介质，相速度以及因此传播通过条带的RF信号的相移 可以控制传输介质。
