Si integration with millimeter wave phased array antenna

摘要

Radiating aperture and beam-forming networks are key components of advanced military and commercial wireless systems, and new technologies are needed to meet the desired performance goals. To achieve a reliable, efficient and highspeed Wireless LAN (WLAN, IEEE802.11) and wireless metropolitan area network (WMAN, IEEE802.16) a system must provide the following characteristics: 1. Electronically beam steerable for quick switching between terminals and to minimize multipath effects. 2. Wide bandwidth to accommodate high throughput rates. 3. Sufficient power capabilities to ensure adequate received power levels maintaining constant robust communications link. However, radiated power intensity must not exceed safety limits. 4. Narrow beamwidth to permit angular diversity usage. 5. Small, lightweight, low profile and conformable to desired surfaces for suitable use in portable systems. 6. Provides simple and flexible setup with minimum usage of wire connections to fixed structures such as walls and ceilings. 7. Withstand interference from human movement and noise from other network sources. 8. Suitable for use with higher millimeter-wave frequencies.
