A novel reconfiguration method based in the use of pixel surfaces as parasitic elements is presented. This concept can be used to provide reconfigurability to a wide variety of non-reconfigurable antennas without requiring additional modifications on the basic antenna design and avoiding any physical interconnections. General guidelines are provided for the design of parasitic pixel surfaces. Reconfigurability...
A MEMS reconfigurable antenna with beam steering capability and resonance frequency reconfigurability is presented. The design is based in an interconnected patch grid structure and employs a hybrid geometry with different sized patches in a biclustered distribution on order to reduce the structure complexity and the number of necessary switches. A small antenna of λ/2 by λ/2 using only 12 RF-MEMS...
The frequency reconfigurable volumetric PIFA presented in this paper is designed to switch between two US public-safety bands, one operating at 700MHz and the other having a bandwidth of 17% around 850MHz — in effect covering a range from 800MHz to 900MHz. The reconfigurability is limited to only the ground and patch layers as an aim to minimize the number of MEMS switches used. The radiation pattern...
