The magnetic current in an annular slot is used to enhance the impedance bandwidth of a monopole and preserve consistent radiation patterns from $ {K}$ -band through ${V}$ -band. The equivalent circuit models of monopole, annular slot, and their combination are derived to aid the RF system analysis with this antenna, herein referred to as a combined annular slot-monopole antenna. The proposed antenna...
In this work, an immunity test based on the Bulk Current Injection (BCI) test procedure is simulated, with the objective to predict the radio-frequency (RF) noise currents injected into the terminations of a CAN-bus line. To this end, an accurate model of the injection probe is combined with typical injection profiles recommended by automotive Electromagnetic Compatibility (EMC) Standards, and with...
This paper proposes a packaged transistor modeling using lumped elements. This model allows studying the input impedance dispersion when a range of variation is applied to various package components. This dispersion is also highlighted when a load impedance variation is applied to the package transistor. It is demonstrated that this dispersion can be corrected using a specific input pre-matching and...
