ΜΕΛΕΤΗ ΟΡΘΟΓΩΝΙΚΩΝ ΚΑΙ ΤΡΙΓΩΝΙΚΩΝ ΜΙΚΡΟΤΑΙΝΙΑΚΩΝ ΚΕΡΑΙΩΝ

THE ANALYSIS OF MICROSTRIP ANTENNAS WITH RECTANGULAR AND THREE TYPES OF TRIANGULAR PATCHES IS GIVEN IN THIS DISSERTATION. THE THEORETICAL ANALYSIS IS CARRIED OUT BY THE USE OF THE OPTICAL RAYS (GEOMETRIC OPTICS THEORY) METHOD. CLOSED FORM EXPRESSIONS FOR THE TOTAL INTERNAL FIELD (UNDER THE PATCH) AND THE INPUT IMPEDANCE ARE GIVEN WITH THE AID OF AN ANGULARLY DEPENDED REFLECTION COEFFICIENT OFA TEM WAVE OBLIQUELLY INCIDEND OF THE EDGE OF THE PATCH. IN THESE EXPRESSIONS THE PRACTICAL FEED SYSTEM AS WELL AS THE FEED POINT HAVE BEEN TAKEN INTO ACCOUNT. THE REQUIRED COMPUTATION TIME IS THE MINIMUM POSSIBLE BECAUSE THE DESIRED QUANTITIES ARE GIVEN IN ANALYTICAL FORM. ESPECIALLY THE TRIANGULAR MICROSTRIP PATCH ANTENNAS HAVE BEEN STUDIED UNTIL NOW ONLY BY THE USE OF NUMERICAL METHODS ASTHE MOMENT METHOD AND THE FINITE ELEMENT METHOD WHICH REQUIRES EXTREME COMPUTATION TIME. THE COMPARISON OF OUR NUMERICAL RESULTS FOR THE RESONANT FREQUENCY AND THE INPUT IMPEDANCE WITH THAT GIVEN BY OTHER RESEARCHERS (WHO USED DIFFERENTMETHODS) AS WELL AS WITH EXPERIMENTAL ONES, SHOWS A GOOD AGREEMENT.
