High transmission gain slot antennas on silicon substrate for wireless interconnect

Some pairs of slot antennas with different slot widths on silicon substrate were designed and analyzed. Numerical results show that compared to the dipole antenna pair with a resonant frequency of 10.5 GHz on low resistivity ( psi = 10 Omega - cm) silicon substrate, the slot antenna pairs have higher transmission gain. As the slot width increases slightly, its transmission gain can be improved significantly. As a result, the silicon substrate with low resistivity has little effect on the slot antenna gain and it can be used in wireless interconnect or WCAN.
