printed dipole calculator
Hello,
I am designing a half wave printed dipole antenna and I have one question: when considering the length of the dipole arms (which should be 1/4*wavelength), what wavelength should I take? Shall I use the free space wavelength - since the antenna radiates into free space - or, the effective wavelength calculated for a microstrip line.
I've read in this article that the considered wavelength is somewhere in between the 2 options. Length=19=wavelength/4 for 2.4GHz, meaning free space wavelength/4=31.25mm the relative permeativity of the dielectric is 4.6.
Thank you!!!
