Abstract :
This paper discusses results from a comprehensive investigation into the performance of two ground planes with various angle and ratio. Results from numerical simulations and measurements on prototype hardware are presented to show the influence of angle and ratio on resonant frequency, bandwidth, return loss of centre frequency, gain, and radiation patterns. Present data are very useful in the design of a fold-type handset.
