Microstrip antennas on multilayer cylindrical and quasi-cylindrical structures

IEEE Antennas and Propagation Society International Symposium. 2001 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.01CH37229), 2002
A method to analyze cylindrical and quasi-cylindrical multilayer microstrip antennas is presented. The method is based on the integral equation technique in combination with spectral domain approach. In the first step the dyadic Green's function of the cylindrical structure is derived in the spectral domain by the use of an equivalent circuit.

Four-point error separation technique for cylindricity

Measurement science and technology, 2018
A four-point error separation technique integrating three-point roundness and two-point straightness error separations is proposed to measure and reconstruct a cylindrical profile for the accurate evaluation of cylindricity.

Cylindrical and Cylindrically Warped Strip and Microstriplines

IEEE Transactions on Microwave Theory and Techniques, 1978
The impedances of cylindrical and cylindrically warped strip and microstriplines are presented. Applications include rolled-up circuits using flexible dielectric material, transition adapter, balun, slotted line, and other special transmission lines. Effects of warpage on the impedances of planar strip and microstriplines are also presented.

A V-block three-probe error separation technique for portable measurement of cylindricity

Precision engineering, 2019
A three-probe error separation technique with a novel V-block for measuring and reconstructing a cylindrical profile is presented. The V-block has two tandem V-shaped planes and three displacement probes mounted in one section.

Radiometric system cylindrical radiator-cylindrical endface detector

Atomic Energy, 2000
A radiometric system for radiators placed flush against the outer surface of the detector is analyzed. The geometric factors which take account of the extended nature of the detector are calculated for three values of the relative thickness. It is shown that for a detector with thickness less than 1.57 the geometric factor decreases with decreasing ...
