Small antennas, or more specifically, electrically small antennas, are passive radiating elements whose size is much smaller than the operating wavelength. The current wireless application systems usually have size constraints that, for the most common ope ...
This study reports an experimental study of the system fidelity factor (SFF) of ultra-wideband wireless body area network antennas in an on-body environment. This study also investigates the influence in the SFF because of the antenna polarisation with res ...
Body-centric applications include wearable communication systems that can be integrated in many different applications, as for instance in military, security forces, sport, fashion, or medical. In the latter, the quality of life of patients can be greatly ...
Antennas are an important element of Wireless Body Area Network equipments, as the quality of the antenna and its coupling to the channel will be a key component of the quality of the overall link. Indeed, the antenna and its interaction with the body of t ...
This communication presents a reconfigurable antenna capable of independently reconfiguring the operating frequency, radiation pattern and polarization. A switched grid of small metallic patches, known as pixel surface, is used as a parasitic layer to prov ...
A new low profile ultra-wideband (UWB) antenna for wearable applications is presented. Its structure is derived from the quadripod kettle antenna (QKA) [1], and is called tripod kettle antenna (TKA). The proposed antenna is very well suited for wearable ap ...
In recent years, the advancements of wireless technologies have led to rapid developments in the field of telecommunication, power delivery and bio-medical applications. During the evolution of a wireless technology, the electromagnetic compatibility (EMC) ...
A tapered composite right/left-handed (CRLH) leaky-wave antenna (LWA) with reduced sidelobe level (SLL) is presented. A cosine taper design is achieved by simultaneously modifying the longitudinal period and the slot width of the mushroom CRLH structure. T ...
In this work a conceptual design of a conformal antenna array is presented for a millimeter-wave antenna system, optimized for low-cost mass production in PCB technology. The conformal array is constituted by four cube faces with two antennas realized on e ...
