Hi..I've design a stacked patch microstrip antenna..the lower patch (actually i used a meander line type structure) is coaxially fed and upper(parasitic) patch size is different from that of lower patch(meander)..resonant frequency of my lower patch is 1.3 GHz..When i use a stacked parasitic...
Hi..can anybody explain, what exactly happens when a rectangular slot is introduced in the patch? in terms of surface current or any other means..how bandwidth is improved when slot is introduced? please help
Thanks :)
I am new to CST and facing lot of difficulties. I am trying to bend the cpw fed monopole antenna but whenever I am simulating I am getting the error "port 1 is inhomogeneously filled within the first three mesh cells. Cannot start solver."
I am also enclosing the structure that I have...
hi...i want to design a patch antenna with 12% bandwidth and 120 degree beamwidth..so far i ve achieved 115 degree beamwidth and 8.8% bandwidth with meander line element on a rtduroid substrate (er=2.2) n i have also introduced an airgap of 25.4mm between ground and substrate..freq of operation...
hello...i have attached a cpw monopole file...plz chk dis out..i m nt pretty sure abt the design equation of cpw feed...length of the feed..for 450mhz..polycot as substrate,...its urgent ...plz do reply....
thanx
