The new Integral antenna design provides gain equal to or better than the currently used cellular antennas. For more information, see our recent press release concerning test results on the CDMS PCS antennas. If you would like the full text of the independent test report, please provide me with your fax number. Antenna diversity is a commonly-used technique to improve signal quality on the receiving radio (it is not used on the transmit side). To my knowledge, all cellular base stations employ diversity receive antennas. Some cellular data terminal devices (CDPD modems, for instance) employ diversity receive antennas as a means of keeping signal quality and concomitant bit error rates within specs. It's been a while, but I seem to remember that Rayleigh fading has less to do with the antenna and more to do with the operating environment (reflectors and absorbers) and the constructive or destructive effects of in-phase and out-of-phase signals. To my knowledge, no specific tests have been done to compare Rayleigh fading characteristics of the CTHA to those of conventional antennae. I would speculate that there would be no material difference. The pioneering work on CTHAs was done several years ago at West Virginia University by some graduate students working for Dr. Smith. The new Integral design is a next-generation design, and was not developed by Dr. Smith or his students. Best regards, --Mark Williams williams@itechfin.com
