A Critical Study of the Circuit Relations of Two Distant Antennas

چکیده
In this work, we present a critical s tudy of the circuit relations for two distant coupled antennas: either both are transmitting, or one is transmitting a n d one is receiving. W e found that Carter’s two mutual impedances , Z t2 and Z 2 , , a r e not applicable to t h e s e two c a s e s . Two sets of circuit relations have been formulated, with two sets of wave impedances , to characterize t h e s e new circuit relations. It is shown that the coupled wave impedances are not equal to e a c h other, a n d they satisfy a conjugate relation with a negative sign. S u c h a relation also applies to Carter’s Z12 a n d Z,,

In In this paper, two low profile, single fed cavity backed slot antennas providing a circularly polarized (CP) wave are introduced. One of the antennas presents a right-handed CP (RHCP) wave, while the other one offers a left handed CP (LHCP) wave. The proposed antennas consist of a square shaped Substrtae Integrated Waveguide (SIW) cavity incorporatng two couples of radiating slots to radiate...

متن کاملCritical Study of Right to be wrong From the point of view ofcollectivists, utilitarians, and virtuosos
circuit right discourse is one of the most common theories in the contemporary period about regulating human social relations. The formation of this course of thought and the exhibition of a unidimensional understanding of the concept of right in the West is the result of socio-political changes in the seventeenth and eighteenth centuries. It was during this period that thinkers’ response to th...
متن کاملEquivalent Circuit Model for Square Ring Slot Frequency Selective Surface
An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...
