Elliptical shape microstrip patch antenna without dots

This paper introduces the performance of an elliptical shaped antenna with random slots and compares the results between the original patch and the patch without dots. 5.8GHz is the reference or desired frequency set for measuring the performance of this antenna. For the design, three elliptical shaped slots with different dimensions are deployed and connected to each other acting as a main radiating element with coaxial feeding as the excitation method. While, 14 cylindrical dots with different radius are positioned at the left most center of the smallest elliptical slot. An additional slot is created for the coaxial feed point at the center of the radiating patch to allow equal surface current distribution. The antenna is capable of functioning with a maximum directivity of 6.948dBi with a return loss of -22.87dB. Moreover, the proposed antenna radiates in an elliptical polarization pattern where the axial ratio measured is more than 1. The antenna is proficient to be applied in modern communication systems especially point to point communication where it functions at the same bandwidth range.
