RFID for UHF

[eddyann 3]

The antenna working frequency should be well enough to operate from 898 MHz to 934 MHz which suitable for UHF RFID application. I will share later once the antenna has been constructed and tested with the network analyzer

[eddyann 3]

The dimensions (in mm)

Diameter =
dr reflector 240,
dv driven 179,
d1 director 1 154,
d2 director 2 135,
d3 director 3 133,
disc thickness 1 
boom 5,

feedpoint from center 65,
boom length 210,

Gap =
dr to dv 15.5
dv to d1 21
d1 to d2 88
d2 to d3 78

,,,to cover this frequency range....

 

,,,,a good antenna can be this yaga....
