This paper presents a preliminary investigation on the body proximity cross-polarization properties considering the human walking motions for BAN on-body wireless communication systems. A novel concept of the BP-XPR (Body Proximity Cross-Polarization Power Ratio) in on-body channel is defined, which has been quantified based on relative antenna locations and radiation gain of test antennas. The analytical...
In the research project, a design concept of the mm-wave antenna array operating at 38 GHz is proposed by using a 64-element micorstrip patch antenna array. Theoretical and experimental study validates the design approach for the use of the Fifth generation (5G) wireless communication system.
This paper presents a high-linearity and high-gain power amplifier for 802.11p standard. The power amplifier is fabricated using InGaP/GaAs HBT technology and packaged in a 5×5mm QFN. A stand-alone integrated passive device (IPD) chip is exploited as the output matching network in the same package. The measured power gain is 25.8 dB at 5 V supply. With a 27 Mbps IEEE 802.11p signal at the center frequency...
