Slot antenna finite ground plane

By Admin

Technical Feature A Large Bandwidth T-shaped Microstrip-fed Ground Plane Slot Antenna The characteristics of a T-shaped microstrip feeding a ground plane slot antenna have been analyzed using the finite difference time domain (FDTD) method. The impedance and bandwidth of the proposed antenna depend highly on the design parameters. The...

This paper examines the effect of a finite ground plane on the radiation patterns of waveguide slot antennas. A hybrid geometrical theory of diffraction (GTD) method is presented to calculate the UWB Slot Antenna on a Folded Finite Ground Plane - An innovative antenna based on a printed rectangular slot etched in a finite ground plane which is folded conformably to a boxed structure is proposed for UWB applications. The antenna is fed by a 50Omega microstrip line printed in a dielectric substrate. Due to geometry, the finite folded ground allows the far-field radiation patterns to fill the entire space. CPW-fed capacitive coupled slot antenna with finite ground In this paper, design of slot antenna fed by CPW through capacitive coupling with finite ground plane is presented. The propose antenna exhibit perfect impedance matching, unidirectional radiation

A prototype of the bow-tie slot antenna is fabricated and the return loss is measured using the HP 8510C vector network analyzer (VNA). The fabricated antenna has a finite ground plane truncated at 1 cm away from the bow-tie slot edge. The antenna with the connector is simulated

The introduction of a ground slot in a finite antenna ground plane can be further extended to include reconfigurable features. Antenna (radio) - Wikipedia 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.
