Abstract
The advancement in wireless communication technology has accelerated the use of patch antenna in the field of microwave and millimeter wave applications. This paper work illustrates the design and measurement of diamond shape microstrip antenna for 2.7/7.36/8.58 GHz applications. The antenna has been designed and simulated using Zeland IE3D 9.08 microwave simulator. The proposed structure consists of a rectangular ground plane, on which the rectangular section is rotated at an angle of 45°, which looks like a diamond-shaped section, in which diamond-shaped slots are incorporated, and the antenna is split into two parts at a gap of 0.5 mm to improve impedance bandwidth using slotted coupling. The bandwidth of the fractional impedance of the proposed antenna is 15%, 5.4% and 2.3%, respectively when simulated and 5.9%, 5.4% and 2.3% respectively, when measured with a maximum gain of 6 dBi.
