Power transmission gain measurements of integrated antenna pairs in indoor and outdoor environments [single chip transceiver applications]

Currently, a monolithically integrated true single chip radio with a working frequency of /spl sim/24 GHz, a data rate of 100 kbits/sec, and a range of 1-5 m, is being developed for implementation in a CMOS technology. This device uses on-chip antennas and a long dipole antenna is a logical choice for evaluation. This paper reports integrated antenna pair gains as a function of separation in several indoor and outdoor environments for communication over air at antenna heights above ground ranging between 4.5 cm to 85 cm.
