This paper addresses the design and development of HiperLAN antennas meeting the IEEE 802.11a standards for wearable applications. Five such antennas are investigated for their performance characteristics, out of which three are conventional copper based antennas and the remaining two are fully fabric antennas. The results reveal that all the proposed antennas are suitable for HiperLAN applications yielding antenna gain in the order of 7-11 dBi. This study demonstrates that fully fabric antennas outperform the copper based antennas.
