Abstract

Microstrip Patch Antenna (MPA) with narrow beam is proposed in this paper. An intention is to put forward this work to show that MPA can be used to make antennas of directional nature with focused beam. Proposed system is an array of antenna using MPA without going in the domain of multiple antenna system, thereby reducing the need of separate feed to individual antennas to a common feed. The points which are considered in this work are decrement of beam-width with increase in array size and close look on the gain of the resultant antenna. All the simulated designs are carried out at the frequency of 11 GHz with a ground size for single patch antenna as (10.5 15 1.6) mm. However, the size of the ground changes with different array configuration. The software platform used for this work is High Frequency Structure Simulator (HFSS) and the prototypes were fabricated on FR4 epoxy board. The difference in the radiation pattern, gain and beam-width of the antenna is shown in the later section of the paper for different array configuration.
