AN INJECflON LOCKING METHOD FOR MULTIPLE PET OSCILLATORS SUITABLE FOR ACTIVE PHASED ARRAYS AND QUASI-OPTICAL POWER COMBINING 1. Birkeland and T. Itoh* ABSTRACf In this paper we present a new method for the mutual injection locking of large numbers of PET oscillators. This is accomplished by taking advantage of the non-reciprocal nature of the PET, using the gate of the device as the locking signa

~WAVE ELECTRICALLY SCANNING STRUCTURE WITH FERRITE CONTROL E F Zaitsev N P Milevsky ABSTRACT ANTENNA ON PLANAR GYROTROPIC , Y P Yavon , Y A Komarov , A N Puzakov , A Y Kanivets A new antenna, based on a travelling wave antenna principle, is presented. Antenna consists of a ferrite-dielectric waveguide and microstrip dipoles, which are placed along on a surface of the waveguide. The phase veloci

APPUCATION OF THE TLM METHOD A NEW ABSORBING BOUNDARY TO SLOT ANTENNA ANALYSIS FOR THE TLM METHOD IEMO - ENSERG F. NDAGLJD/IANA, P. SAGUET, II. BOUTBINON B.P. 257 38016 GRENOBLE cedex: FRANCE ABSTRACT The TLM method is used to characterize tapered slot antenna radiation. This method enables the calculation of field distribution at any point of the radiating structure and for any band of frequ

THE CONVOLUTION APPLIED ON THE SYNTHESIS SHAPED BEAM . F. Ares* ABSTRACT and E. Moreno* We present an efficient and flexible method for the optimal synthesis of shaped beam linear array. The technique is based on the convolution of the desired pattern and a scanning function. The amplitude of the ripple in the shaped region and the height of the sidelobes in the nonshaped region are controlled.

SCATTERING BY THE INFINITE IfICROSTRIP-PATCH ARRAY. A.S.IlYinsky*, V.I.Ivakhnenko*. ABSTRACT. The paper deals with the problem of eleotromagnetio soattering by the infinite reotangular miorostrip-patoh array. The boundary problem for Maxwell's equations in stratified media is reduoed to the eleotrio field integral equation for the unknown surfaoe ourrent distribution on the patoh in a unit o

A RAPID METHOD FOR ARBITRARY FFT-ALGORITHM MICROSTRIP STRUCTURES USING THE G. Splitt ,) ABSTRACT A rapid method is presented to calculate microstrip structures with arbitrary shape embedded in multilayered dielectric. The current is divided into small rectangular subdomains and is approximated with triangular basis functions in x- and y- direction. A modified Galerkin procedure is applied in

A NEW EXTREMELYWIDEBANDLUMPED SIX-PORT REFLECTOMETER V. Bilik, ABSTRACT V. Raffaj, J. Bezek* The six-port reflectometer structure has been invented which may consist solely of lumped'elements, is inherently dissipative but extremely broadband, covering bandwidths up to 3 decades of frequency. The contribution outlines the principle of operation of the device and presents some experiments with a

X-Band Homodyne Network Analyzer using a Broadband Computer- Controlled SSB-Modulator B. Schonrock, R. Knochel* ABSTRACT A homo dyne network analyzer (NWA) is presented that applies a novel SSB-modulator for modulating the test path. The unwanted or image sideband is suppressed more then 40 dB over the 8-12 GHz frequency range using a microcomputer to adjust the modulator to its optimal operatin

EXPERIMENTAL RESULTS OF NEW FOR NETWORK SELF-CALIBRATION ANALYZERS * PROCEDURES H.J. Eul and B. Schiek ABSTRACT: A general theory for network analyzer calibration is presented. From this theory calibration procedures are derived which allow to evaluate the values of unknown parameters in the calibration standards during the calibration procedure via eigenvalue conditions. The performance of t
