I have simulated a rectengular patch antenna(linefed) at the centre frequency of 2.4 GHz. The results (S11 and VSWR) are so confusing.. the whole plot of s11 is below -8dB and VSWR below 1.80.. Is it correct..? How can we calculate gain and bandwidth in that plot?? What is the formula to...
What is the criteria to decide on the position and size of waveport in aperture coupled Microstrip patch antenna and linefed microstrip patch antenna???
this is the 3D polar plot.. plz tell me if i have taken the right coordinate systems?(theta and phi) if not then what is the criteria? another fig is the gain vs theta... is it correct?
i have simulated a aperture coupled patch antenna. the plot of gain is intersecting the axis near 0db. I want to know, what does it mean actually? can anybody plz tell me how to analyze the graph?
