length, and probe displacement on the radiation performance of the antenna including resonant frequency, input impedance, radiation patterns, and bandwidth are investigated. The results obtained for the antenna parameters based on the MoM investigation...

A complete equivalent-circuit model of input impedance is developed for a hybrid antenna, which consists of a Half Mode Substrate Integrated Waveguide (HMSIW) resonator and a microstrip patch. An accurate circuit

model is derived using...

In this paper, a low-power electroencephalogram (EEG) analog front-end (AFE) with ultra-high input impedance is presented. This AFE can be utilized for both dry and non-contact biomedical applications due to its very high input impedance along...
