Abstract
Two novel designs of dual-mode beam-steerable array antennas are proposed for customer-
premises equipment applications. To obtain the optimal distribution of excitations for the arrays, the gain
and front-back ratio of the array systems are optimized by using the method of maximum power transmission
efficiency. The first design operates at 2.45 GHz and uses four folded monopoles of height<1/10 wavelength
and a sleeve of height of 1/4 wavelength underneath the monopoles. The peak gain and the front-to-back ratio
are 6.7 dBi and 7.8 dB respectively. The second design operates at 830MHz and uses four Yagi monopoles as
elements with a common reflector and four directors. The peak gain and the front-to-back ratio for the second
design are 6.0 dBi and 16.8 dB respectively. The proposed antennas have advantages including: low cost
and compact size; dual-mode operation including the modes of omnidirectional radiation and directional
radiation; and in the mode of directional radiation, the beam can be electronically steered to achieve the full
coverage of the azimuthal plane. It achieves higher gain than the traditional electronically steerable passive
array radiator antenna.
