Thus the antenna's impedance, given by the ratio of feedpoint voltage to current, is altered due to the antenna's proximity to the ground. Dipole antenna - Wikipedia This contrasts with a monopole antenna, which consists of a single rod or conductor with one side of the feedline connected to it, and the other side connected to some type of ground. [8] A common example of a dipole is the "rabbit ears" … Wideband Planar SLOT Antennas - PDF The measured return loss for the finite ground plane bow-tie slot antenna has a bandwidth of 52%, which is better than the simulation results. 0 Return Loss (db) FDTD ADS W 1-10 L 1 L 4 W 2 Lcpw L 2 L 3 S1 S2 S1 Fig. Broadband Metamaterials in Electromagnetics | Metamaterial…

Reflection Phase Characterizations of the EBG Ground Plane for Low Profile Wire Antenna Applications Fan Yang, Member, IEEE, and Yahya Rahmat-Samii, Fellow, IEEE Abstract— Mushroom-like electromagnetic band-gap (EBG) structures exhibit unique electromagnetic properties that have led to a wide range of electromagnetic device applications. This ... Design and Study of Compact and Wideband Microstrip U-Slot ... antenna location with respect to the ground plane. From his results, it appears that variation of the size of the finite ground plane seems to have similar effect on both U-slot and rectangular patch antennas. In 2004, R. Urban and C. Peixeiro [16] reported the effects of ground plane size on a microstrip antenna performance for small handsets.
