Performance characteristics of a conformal ultra‐wideband multilayer applicator (CUMLA) for hyperthermia in veterinary patients: a pilot evaluation of its use in the adjuvant treatment of non‐resectable tumours

“…tissue matching properties), EFS and overall efficiency; however, the bidirectional irradiation of slot antennae may lead to safety concerns. The addition of multiple layers to the flat antenna construct allows for the addition of a floating ground plane and additional slots; thus improving directionality and efficiency, respectively 5–7,10 . Manipulation of the size and shape of individual slots can lead to reductions in antenna size and changes in resonant frequency 5,10 .…”

The addition of metamaterial‐inspired periodic structures can further reduce antenna size and improve efficiency 11–14 .…”

Radiation Pattern Measurement of a Low-Profile Wearable Antenna Using an Optical Fibre and a Solid Anthropomorphic Phantom

“…To improve the antenna radiation efficiency and reduce the power absorption by the body, methods such as adding an additional spacer layer [20], electromagnetic band gap substrates [21], reflection plane substrates [22] or textile fabric substrates [23] between the body and the wearable antennas have been proposed. Furthermore, when designing the antenna the body proximity effects must be considered to prevent significant antenna detuning and the consequent mismatch [19,24]. One method is to optimize the impedance matching when in proximity to the tissue.…”

“…However, such method may suffer the resilience to proximity detuning when the antenna-to-body distance varies. An improved design method to develop the antenna to have good impedance matching in the presence of tissue and also to have resilience to distance-dependent antenna detuning has been proposed in [24].…”

Temperature field simulation and phantom validation of a Two-armed Spiral Antenna for microwave thermotherapy

“…Since microwave (MW) thermotherapy has the advantage of providing a comfortable and painless treatment environment for patients, it has been used in medicine for cancer treatment and the treatment of other diseases since early eighties [5,6]. Researchers have designed many types of radiators that are suitable for therapy on superficial tumors [7][8][9].…”
