Abstract:
Ultra-wideband phased array antenna technology is critically important in fields such as radar and communications. The co-design of multi-domain characteristics (e.g., frequency, polarization, and spatial domains) represents a key challenge. For instance, airborne platforms require antennas with low-profile and miniaturized structures, meaning constrained apertures in either longitudinal or lateral dimensions. Simultaneously, these antennas must meet the performance requirements of integrated multifunctional applications in terms of wide bandwidth, low cross-polarization, and wide beam coverage. However, current technologies often focus on single or limited performance aspects, failing to satisfy the stringent demands of multifunctional integration. This talk thoroughly discusses co-design methods and key technologies for achieving multi-domain performance in ultra-wideband phased arrays under structural constraints.
