Abstract:
The demand for higher data throughput in wireless
communication has led to exploration of the D-band (110-170 GHz) due to its potential for near-100
Gb/s data rates. High- gain antennas and beamforming transceivers are essential for overcoming
challenges such as high propagation losses and low output power at these frequencies. Phased
antenna arrays, particularly those based on compact patch antennas, show promise for 6G
wireless technologies. However, comprehensive system-level modeling for large N-by-N arrays in
this frequency range is lacking. This paper presents an innovative approach merging
electromagnetic (EM) and system-level modeling to analyze N-by-N phased antenna arrays (3 :S N :S
20) at 150 GHz. The modeling process is detailed, encompassing the design of a 150 GHz patch
antenna and array synthesis in HFSS, followed by system-level simulations in SystemVue. The impact
of beam steering on directivity and beamwidth is explored, both with and without phase
quantization. Additionally, the effect of antenna element failure on directivity is investigated
for 5-by-5 and 16-by-16 arrays, highlighting the significance of array size in performance
resilience. The power consumption implications of array size are discussed, emphasizing the
benefits of larger arrays in achieving a given system gain with fewer amplifiers. Finally, sidelobe
level reduction is explored using Taylor tapering, resulting in decreased directivity and increased
beamwidth, with specific trade-offs analyzed for different array
sizes and steering angles.
