Abstract: The tremendous growth of modern wireless communication devices enabling the design of compact microstrip patch with wideband behavior is becoming more attractive. The challenge is always put to the engineers to design a simple antenna that is low cost, compact and efficient for simultaneous communication in multiple frequency bands. The four proposals in this paper provide the best investigations for attaining the open challenges in the field of communications in LTE with an acceptable range of results. Iteration-1 works for dual wide bands operating from 8.8 – 14.7 GHz and 20.7 – 25 GHz respectively, which has the wide band notch in between those two bands to avoid interference problem. The improvements being made to the design in each iteration, to extract much better results in terms of resonating frequencies and operating bandwidths are verified in Iteration-2. Even narrow band operating frequency with best results are attained in Iteration-3. The antenna design in Iteration -3 is a narrow band operating antenna with 2.75 GHz being the resonant frequency. In Iteration-4 a triple band operation is achieved for medical band applications.
