INTRODUCTION Mobile devices are in a constant state of evolution given the increasing features and frequencies available worldwide. Today, global handset functionality is becoming an important… (More)
A triple-frequency antenna combining a dual-band and a monoband antenna with broadside radiation patterns is presented. The dual-band antenna is inspired in the Sierpinski fractal. Such a dual-band… (More)
A handset antenna technique combining a parallel excitation of a PIFA and a slot is presented. The number of frequency bands is given by the sum of bands given per each radiator which can be… (More)
It is well known that microstrip patch antennas have a poor bandwidth due to the small spacing between the patch and the ground plane. A stacked patch configuration has been demonstrated… (More)
Experimental verification of the fractal Sierpinski antenna surface current distribution is presented. Measured data from an infrared camera agree with numerical data showing a self-similar behavior… (More)
A dual-frequency antenna based on the Sierpinski fractal with two parasitic patches to enhance the impedance bandwidth is presented. An electrical circuit model formed by RLC resonators is proposed… (More)
A microstrip antenna formed by two stacked patches is proposed for dual-frequency and broad-band performance. Different E-plane and H-plane arrangements are studied to achieve an isolation between… (More)
