The demand for smaller communication devices for personal communication systems has led to a constant search for methods to reduce the cellular phone dimensions. However, the wavelength does not decrease with the same speed as the size of the mobile phones due to the higher frequency bands used. Even...

In present-day wireless communication equipment, the need for antennas of high efficiency has generated much interest in the study of microstrip antennas. These printed microstrip antennas exhibit a low profile and are lightweight. However, microstrip antennas have inherently narrow bandwidths and, in general, are half-wavelength structures, operating in the...

Calibration standards such as opens and shorts have traditionally been modeled by fitting the actual response of the standard to a third-order polynomial. 1 This approach has limitations as the frequency range of the standards increases. Multiple-band models for the same calibration standard were created in an effort to...

Several years ago, a new antenna was developed to address the increasing need for compact wideband antennas. 1,2 The new antenna was presented as a novel spiral configuration best described as a Tapered Area Small Helix (TASH). The original work drew the interest of the US Army Communications —...

In October 2003, the FCC announced that the frequency bands from 71 to 76 GHz, 81 to 86 GHz and 92 to 95 GHz were available for wireless applications. FCC chairman Michael Powell heralded the ruling as opening a “new frontier” in commercial services and products for the American...

Enhanced Wireless Network Simulator Software This wireless network simulator (WNS) software enhances the functions of the MD8470A signaling tester — a base station simulator for mobile terminal application software development and verification. It establishes interactive operation between the MD8470A and a W-CDMA or GSM/GPRS mobile terminal and simplifies the...

Industry News Radiall has bought New Haven, CT-based Applied Engineering Products Inc. (AEP). The newly acquired company ranks among the largest of the independent designers and manufacturers of the subminiature coaxial connectors and cable assemblies, used in high reliability radio and microwave frequency applications. Their products are sold primarily...

Harris Corp. announced that it has been awarded a $35 M contract modification by the Federal Aviation Administration to upgrade the voice communications displays used by the nation’s air traffic controllers as part of the existing Voice Switching and Control System (VSCS) contract that the company was awarded in...

XTAR LLC announced that it has been awarded a contract with the US Department of State’s Diplomatic Telecommunications Service Program Office (DTS-PO), Fairfax, VA, to provide X-band communications services to embassies and consulates in Africa and Asia. The five-year contract has an estimated maximum value of up to $137...

The Air Force announced that Lockheed Martin has been selected to continue development of the Innovative Space Based Radar Antenna Technology, known as ISAT. The contract, valued at $19.5 M, is for the next phase of the Defense Advanced Research Project Agency’s (DARPA) ISAT project, administrated by the Air...
