Description
Book SynopsisA microstrip antenna consists of a thin metallic conductor bonded to a thin grounded dielectric substrate. Such an antenna is very compact and suitable for portable communications equipment. Compact microstrip antennas are of great importance in meeting the miniaturization requirements of modern portable communications equipment.
