Monopole antennas modeling and WIIC communication study based on PCB medium
In a proposed two layer printed circuit board(PCB) structure,a monopole antenna is designed for wireless inter/intra chip(WIIC) interconnection applications.The antenna is not only to fix the chip,but also used as radiation antenna of I/O ports.Two antennas operating at 20 GHz are separated by one wavelength,and printed inside the PCB medium as an extension of the chip pins.Both upper and lower plates are built with copper.HFSS is employed to simulate the scattering parameters.It is found that the magnitudes of S_(11) and 5_(22) are 12.7 dB and S_(21) 18.3 dB.Herein the transmitter antenna is excited with a series of Pseudo Random Binary Signal(PRBS) signals with the high and low voltage of 1V and 0 V and the bit cycle of 50 ps.The receiving signals are represented as the eye diagrams at the receiving antenna.This investigation shows the feasibility of implementing RF and wireless communication techniques by using chip pins as transmitting or receiving antennas in the new PCB.
