The design approach of a loop-dipole combined antenna for wearable applications is proposed. In order to mitigate the antenna's performance deterioration caused by the human body, additional loops are incorporated with a wideband dipole. The loops can i) widen the impedance bandwidth by minimizing the reactance of the antenna, ii) increase the antenna's directivity and iii) act as wearable accessories...
A complementary antenna for wearable applications is proposed. By introducing a loop-monopole combined structure, unidirectional beam is obtained and the interaction between the antenna and the human body can be potentially mitigated. The antenna's operation principle is analyzed and validated at first. Then, prototypes are designed and measured. When the antenna is placed in free space, an impedance...
The channel impulse response (CIR) under indoor stair environment is modeled. In this model, the amplitude and phase of the CIRs are described as Weibull and uniform distributed random variables, respectively. The CIRs can be simulated using the proposed model. Then, Orthogonal Frequency Division Multiplexing (OFDM) communication system is implemented on the measured and simulated channels. Based...
