Abstract The aim of this paper is to describe the results obtained by experimenting with a Composite Right/Left Handed Co Planar Waveguide (CRLH CPW) zeroth-order resonating antenna on ferrite substrate magnetically biased DC magnetic field. CRLH structure consists series connected CPW interdigital capacitors and parallel ground transmission lines as inductors form an working at frequency 13,350 GHz. for has saturation magnetization 550 G, dielectric constant 13.5 resonance linewidth 16.8 kA/m. If device subjected biasing field ranging between 0 T 0.26 T, modeling demonstrates tuning about 450 MHz (meaning ∼ 3.4%) result variation. Also, scanning radiation pattern occurs when polarized. Data measurements indicate deviation +12° −10° variable 0.16 respectively. originality approach in highlighting possibility changing parameters supported using external experiment validates data modeling.
