Small dual L-shaped printed antenna with low cross-polarized fields

摘要

This paper presents a dual L-shaped printed antenna that is small in size with low cross polarised fields. The antenna consists of two L-shaped shorted patches and a feed network with a 180-degree phase difference applied to each antenna probe, etched on a high dielectric substrate located beneath the ground plane. The performance of the new antenna is studied with its return loss and far-field radiation patterns presented here.
