A Functional Microstrip Circuit Module for Annular Slot Antenna
Abstract—A functional microstrip circuit module for annular slot antenna is proposed. This module consists of an annular microstrip line component, two PIN diodes and a DC bias circuit. Reconfigurable circular polarizations can be simply controlled by this functional module. Axial ratio is adjustable by changing the clip angle of the notch made by the annular microstrip line component. Simulate...
متن کاملA Novel Frequency Reconfigurable Slot Antenna
A novel frequency reconfigurable slot antenna is designed for cognitive radio system. In cognitive radio system the two antennas are required one is a wideband antenna and another is frequency reconfigurable antenna. In this work a frequency reconfigurable slot antenna is designed between the switchable frequency range i.e 7.347.96 GHz at eight different frequency band and capable to operate si...
متن کاملA Circularly Polarized Annular-ring Patch Antenna with a Groundplane EBG Annular-slot Array
The effects of tuning the parameters of an annular-ring circular patch antenna with a cross-slot are analyzed and discussed. Then, based on this structure, a novel antenna with an electromagnetic bandgap cell system, which consists of a 4×4 annular-slot array in the groundplane, is designed and both numerically and experimentally evaluated. When compared to the annular-ring patch antenna on a g...
متن کاملAnalysis of Frequency Reconfigurable Annular Slot Antenna for 3 to 7GHz
A new kind of double short strip and single-side micro strip type antenna architecture to develop a frequency reconfigurable annular slot antenna. The design and characterization of this "reconfigurable antenna (RA) annular slot" which was built on a microwave laminate TMM10i Rogers (permittivity=9. 8, loss tangent=0. 002), are presented in this paper. By increasing and decreasing the...
متن کاملComputational Analysis of Annular Ring Slot Loaded Microstrip Antenna
This paper presents an investigation conducted on annular ring slot loaded microstrip antenna operating in triple band and it is found to exhibit frequency tunability with the slot angle. Return loss of the proposed antenna has been investigated as a function of slot angle ? with fixed coaxial feed location. It is found that the said parameter of antenna depends heavily on the slot angle ?. Res...
