Multiport Compact Stacked Patch Antenna For Multichannel Dynamic Directional Modulation

In this contribution, we investigate a multiport compact stacked patch antenna with 360° beam steering when transmitting multichannel dynamic directional modulation. Two secure observation angles that can be chosen freely in XY plane will be considered. The antenna behavior in the main beam and the side lobes is assessed through bit error rate simulations for different observation angle pairs. Trade-offs between security and power efficiency are also discussed.
