Rasheed, Mahmoud M. Aubais Abstract: A hexagonal microstrip antenna that operating at a frequency of (2400MHz) was designed using (CST Studio suite 2021) program for the purpose of studying its properties (i.e. radiation pattern, bandwidth, directivity and return losses). Two slits in the patch of the shape of a golf-putter were drilled. An increase in bandwidth (1.6%-5.35%) was obtained with almost keeping the radiation pattern and directivity. Different insulating materials were used which all led to an increase in the bandwidth. In addition, the insulating material with the presence of the two slits were increased, which resulted in a slight additional improvement in the bandwidth.
