Slot Loaded Square Microstrip Patch Antenna for Dual Band Operation

摘要

In this paper, a design to obtain dual band performance in square microstrip patch antenna has been proposed. This high directive probe feed antenna has only 30 mm × 30 mm patch. It provides dual-band operation by means of three narrow slots close and parallel to the patch radiating edges. It shows quiet analogous and satisfactory radiation pattern at both frequencies in the face of using a relatively facile feeding technique named co-axial feeding. The directivity of proposed antenna is above 6.5 dB at both bands. The dual band results and their radiation performances are observed using 'CST Microwave Studio' based realistic simulations. In short, realistic numerical simulation of a novel design is presented in this paper, considering losses and the presence of the antenna feed, showing how a practical realization is foreseeable.
