Parametric analysis of a broadband Archimedean spiral antenna with cavity
In this article an Archimedean spiral antenna is designed and analyzed that has good operation in broadband application. By analyzing this design, the effects that different parameters have on antenna operation will be studied and ways of optimization will be found. Influences of cavity height and number of turns to obtain good matching and gain in a frequency interval of 4 to 18 GHz will be d...
متن کاملELLIPTICAL MICROSTRIP ANTENNA Resonant Resonant Resonant
above equation the first order formula for the resonant frequency of elliptical microstrip antenna on ferrite sub-strate is found to be (7) The effective permeability of the substrate is expressed as9 = (+ J , where C and D are a function of b/h. Similarly the effective permittivity is expressed as +*(I + 12h/b)-'j2 e, + I &e// = 2 2 which is also a function of b/h. Since b is not uniform throu...
متن کاملResonant Cavity Enhanced
Resonant Cavity Enhanced (RCE) photodiodes are promising candidates for applications in optical communications and interconnects where ultrafast high-eeciency detection is desirable. We have designed and fabricated RCE Schottky photodiodes in the (Al,In)GaAs material system for 900nm wavelength. The observed temporal response with 10 ps pulse width was limited by the measurement setup and a con...
متن کاملDevelopment of A Compact and Low Profile Cavity Backed Slot Antenna Using Microstrip Gap Waveguide Technology
Proof of concept of a cavity backed slot antenna based on inverted microstrip gap waveguide (IMGW) technology is presented. Since the antenna is operating based on the first resonating mode of the cavity, it is more compact compared to the ordinary cavity backed slot antennas in which the second cavity mode is used for radiation. Furthermore, the proposed antenna element introduces lower lo...
متن کاملLong Josephson junction in a resonant cavity
We present a model to describe an underdamped long Josephson junction coupled to a single-mode electromagnetic cavity, and carry out numerical calculations using this model in various regimes. The coupling may occur through either the electric or the magnetic field of the cavity mode. When a current is injected into the junction, we find that the time-averaged voltage exhibits self-induced reso...
