Tunable Dual-Band Antenna-2,4 GHz;5,5 GHz

[Admin 2578]

In this paper, we design and analyze a dual-band rectangular patch antenna with slotted patch,patch and ground plane for 2.5 GHz and 5.2 GHz communications.

hi! try to move to LTE. low band to 800-900 and let's see where the high one will be...

,,,maybe 1800-2100 MHz...!!!

or 1700-2600 )

THIS dual band could be easier...FR4 moderate gain is for 2.4 and 5.2 but could be TWEAKED i think...

,,,,yes, there are many types of antennas here...https://qsl.net/va3iul/Antenna/Printed_and_Microstrip_Antennas/Design_Ideas_for_Printed_and_Microstrip_Antennas.htm

,,,,and this would be a wider band antenna with overall dimensions of 240x240 mm

that's what I was talking about It's quite possible to stretch it to 1700-2700. I think a parasitic element should be made above the lower patch for better matching. or this tipe patch

you can try to do the trick with mimo. copy all the elements and rotate the copy by 90 degrees. it seems to me that the polarization decoupling should be good.

,,,like this...
