in performing system-wide simulations to estimate network system capacities and overall data throughputs. Indoor wireless channels are currently served over GHz, 5 GHz WiFi, and 60 GHz WiGig frequency bands, commonly used for short-range indoor communications. The vast available bandwidth (6 GHz) in the 60 GHz mmWaveFile Size: 1MB. order for a 60GHz system to operate at high data rates at a reasonable range the path loss must be recouped. Other than simply increasing the transmit power of the system, which may not be an option at all, the only way to overcome this loss is by using a high-gain antenna. The only practical way to achieve high antenna gain in a changing or mobile.
The 60 GHz development system and 60 GHz Transceivers from Pasternack enable experimentation and development in the globally-unlicensed 60 GHz ISM frequency band. Common applications include point-to-point links, GigE wireless LAN, radiometry, uncompressed HD video, FMCW radar, scintillometry, remote sensing, campus networks, wireless backhaul and multi-gigabit wireless communications. development has been a S-band antenna first with a coarse breadboard of a 2 degree of freedom (2DOF) antenna pointing mechanism (APM) . After the successful ground testing of the S-band antenna it was decided to advance towards a mechanical steerable Ka-band antenna (see. Fig. 1) system .File Size: KB.

The ICLS was designed to augment the capabilities of the current Tracking and Data Relay Satellite System (TDRSS), providing a data rate capacity large enough to accommodate the expected rates for user satellites (USAT's) in the post timeframe. A new broadband and high gain dielectric resonator antenna for millimeter wave is presented.
The investigated antenna configuration consists of a periodic square ring frequency selective surfaces on a superstrate, an aperture-coupled scheme feed, an intermediate substrate, and a cylindrical dielectric resonator.
