The microstrip patch antennas have limited gain and bandwidth performance. In this paper, an enhancement in the gain, bandwidth, VSWR, return loss and directivity this will make antenna more compact and low profile and this parameter is achieved by slotting an ECE radiating patch and using a defected ground structure and by using proximity feeding and also by techonicCER-10 substrate respectively. The proposed antenna design with a design frequency of 2.45 GHz, (4 to 8)GHz, (8-12)GHz, (26-40)GHz has been evolved isometrically in different designs stages (design iterations). The work of single-band antenna with a slotted patch geometry offering an improved gain but limited in its bandwidth. The change in the widths of the ground, substrate, and the patch along with the addition of slots into this design results in a completely different geometry featuring multi-band operation with an improved parameter performance and the use of defected ground structure in the final stage counters the limited bandwidth operability. All the involved iteration designs have been simulated over CST 2019 for the performance parameters of the reflection coefficient, bandwidth, radiation pattern and gain, VSWR, return loss. The measured results have been found to be in close approximation to the simulated ones.
