EFFECTS OF BEAMFORMING IN MICROSTRIP PATCH ANTENNA ARRAY
ABSTRACT
The article proposes a design and comparison of a different configuration of microstrip patch antenna array (MPA). The comparison was done between a single element patch and 2×2 (4 elements) patch antenna array. Both the configuration contains a microstrip patch antenna on the inset feed type. The designs were compared based on the study of the overall gain of the array configuration, reflection coefficient, VSWR, current distribution, and radiation pattern. From the above-said comparison, the author claims that with the increase in the number of antennae in an array configuration, there is a considerable increase in the gain and decrease in the beam-width. The approach can be termed as beamforming as well. The idea of beamforming says that with the increase in the number of antennas, the resulting beam will show the greater magnitude and lesser beam-width which is exactly matching with the proposed work in this article. To achieve this there are two methods viz. digital and analog beamforming. The approach followed in this paper is analog beamforming. The design was carried at 3.5 GHz on a substrate of type epoxy having a dielectric constant of 4.4.
