PROJECT TITLE :

Compact Printed Parasitic Arrays for WLAN Applications

ABSTRACT:

Antenna arrays enable to achieve high gains and to pick out the most lobe direction; on the opposite hand, these arrays need a difficult feeding network. During this letter, we have a tendency to show that whenever a radiating structure with a planar geometry is preferable and solely a moderate gain (<; half-dozen dB) is needed, a microstrip array composed of an energetic monopole and 2 parasitic elements could be a terribly easy, nevertheless effective style. The phases of the currents flowing through the active and passive components confirm the main lobe direction and will be adjusted during the look procedure by inserting planar meanders. The active element can be fabricated on the front of a commonplace FR4 substrate, whereas the bottom plane and also the parasitic elements are located on the back of the identical substrate. We gift the design and the experimental characterization of each broadside and endfire arrays operating in the wireless native space network (WLAN) band around a pair of.four GHz. The look is extremely straightforward and neat since a balun section is not necessary, thus the proposed antennas occupy a circuit board space smaller than zero.vi λ×zero.five λ.
