Microstrip-Slot Coupler Design—Part II: Practical Design Aspects
نویسندگان
چکیده
Practical aspects of designing microstrip-slot couplers on an AI ~03 ceramic substrate (e, = 9.8) are treated in supplementation of the theoretical analysis of the coupler presented in Part I. Comparison with implemented couplers yields rules for specification of the reference planes at the ends of the coupling section and for the appropriate choice of definition for the slot-line characteristic impedance. Design data of the standard versions of the microstrip transmission line and the slot line are shown to be adequate for the microstrip-slot coupler. Computed S -parmneter curves plotted for various 3-dB couplers yield information on realizable transmission characteristics.

Microstrip-Slot Coupler Design—Part I: S-Parameters of Uncompensated and Compensated Couplers
Using the even-odd mode anafysis of four-port networks with double symmetry, the scattering parameters of the microstrip-slot coupler are derived from the evenand odd-mode parameters of the coupler cross section. The uncompensated coupler and the coupler compensated by extending tbe slot fines are treated and desigo specifications are given covering the compensation slot lines. A comparison wit...
متن کاملDesign of a Novel 3 Db Microstrip Backward Wave Coupler Using Defected Ground Structure
In this paper an edge coupled microstrip coupler with defected ground structure is presented. A normally 7 dB coupler designed on Alumina substrate is converted into a 3 dB coupler by cutting single rectangular slot in the ground plane encompassing the two transmission lines. Other properties of backward wave coupler remain the same, except for a tighter coupling. With this method of design opt...

متن کاملSuperconducting Microstrip-Fed Antenna Coupled to a Microwave Kinetic Inductance Detector
A proper antenna to couple to a microstrip Microwave Kinetic Inductance Detector (MKID) is designed and simulated. A twin-slot microstrip-fed inline antenna is designed for frequency band of 600-720~GHz integrated with an elliptical lens and coupled to the MKID. A systematic design procedure for design of such antenna with microstrip inline feeding is presented. Whole structure of lens and twin...
متن کاملA Harmonic Synchronized Oscillator using Gunn Diodes Embedded on Slot Line Resonators
This paper represents a novel second harmonic power combining oscillator using mutually synchronized Gunn diodes embedded on slot line resonators. A both-sided MIC technology is adopted in the oscillator. The oscillator consists of Gunn diodes, slot line resonators and microstrip lines. By embedding Gunn diodes on slot line resonators, desired harmonic RF signal can be generated very easily. Th...
