multifunctional can bring certain challenges such as increased mutual coupling and complex antenna_x000D_
architectures, all of which variously enlarge antenna footprints, complicate design, and present fabrication_x000D_
challenges. Although solutions exist for these challenges, they may actually increase the size, weight,_x000D_
complexity, and cost of the antenna, and they typically employ ad-hoc or otherwise empirical design methods._x000D_
A separate challenge is the known effect of radomes on radiation parameters. These structures, whose shapes_x000D_
are dictated by application-specific parameters such as wind resistance and aesthetics, are not typically_x000D_
exploited to enhance antenna properties, although they present an interesting opportunity to do so._x000D_
The above challenges demand a more robust solution drawing on new paradigms in antenna design. One such_x000D_
paradigm is that of electromagnetic (EM) 'metamaterials' (MTMs), which are periodic structures engineered to_x000D_
create exotic wave-propagation characteristics - often unavailable using natural materials - and which may be_x000D_
further classified into several types. Among these are EM bandgap structures (EBGs) and certain incarnations_x000D_
of frequency-selective surfaces (FSSs), where the former are typically used to tailor propagation in_x000D_
guided-wave applications (e.g. waveguides and TLs) and the latter are typically used to engineer the_x000D_
transmission and reflection response of waves in free space._x000D_
The proposed collaboration with KP Performance Inc. (Edmonton, AB -- abbreviated KPPA) will investigate_x000D_
designing compact multifunction diversity antennas that incorporate recent advances in MTM-based EBG_x000D_
technology to enable broadband and/or multi-band operation with reduced mutual coupling. A second aspect of_x000D_
this work will examine patterning antenna radomes and ground planes using MTM-based FSSs and EBGs,_x000D_
respectively, to effect better half-power beamwidth roll-off, low side-lobes, and improved front-to-back ratios., program purpose french : In wireless internet service provision (WISP), any efforts to render antennas more compact, low-profile, or_x000D_
