This paper designes an optimized straight CTL cell whose uniform area is 20 mm × 20 mm and generates the dominant E-field and H-field to calibrate small EM field probes by using a wideband balun and a wideband power divider. The fabricated optimized straight CTL cell can operate on the broadband frequency range up to 2800 MHz except 2170 MHz. The(More)
A practical substitution measurement method in a coupled transmission line (CTL) cell was proposed with a half-wave dipole antenna and optical link module for ERP (Effective Radiated Power)/EIRP (Equivalent Isotropic Radiated Power) measurement of a mobile phone. A variable half-wave dipole antenna and an optical TRx module were designed and fabricated(More)
