Coplanar waveguide (CPW) antennas are widely used in wireless communication systems because they can be easily integrated with microwave circuits. This article describes a method for improving the performance of CPW antennas by incorporating a slot into the patch design. The antenna was fabricated on an FR4 substrate with dimensions of 43 mm x 40 mm and a thickness of 1.6 mm. The patch section of the antenna was modified by incorporating a slot. The size and shape of the slot were adjusted to achieve optimal performance. The most effective modified design was then fabricated and its properties were measured. The fabricated antenna exhibited an operational frequency range of 2.24 GHz to 7.30 GHz. It also had an omnidirectional radiation pattern and a maximum gain of 5.825 dB. © 2023 IEEE.
