This communication considers the synthesis of interleaved antenna
arrays with shared and inactive elements. A hybrid genetic algorithm
(GA) where the initial population is seeded with good solutions is proposed.
A number of seeding schemes are considered and themost effective of these
are identified. The proposed algorithm is shown to reliably produce results
with sidelobe level (SLL) values which are close to the optimum and to converge
faster than the other algorithms considered. However, some of the
seeding schemes mislead the GA and actually produce worse results than

The design of antenna arrays involves, amongst others, the selection of the array elements and geometry, as well as the element excitations. The feeding network to obtain the desired excitations can become quite complex, ...
This paper presents a dual-band dual-polarized antenna array design for WLAN applications. Four double-dipole elements are orthogonally interleaved to facilitate operation in both the
standard WLAN frequency bands (IEEE ...
