This paper presents the design, simulation, fabrication and analysis of balance coaxial feed and unbalance coaxial feed microstrip patch antenna with slot for wireless application. The antenna designed was created in Computer Simulation tool (CST)version 2011. This antenna can be applied for 3G and 4G frequency spectrum bands. The simulated frequency of balanced coaxial feed antenna was at 2.6Ghz, while for unbalance coaxial feed antenna was simulated at range of 1GHz to 3 GHz. The analysis was done for the balance coaxial feed antenna in which only single frequency was resulted. Then, the position of the coaxial feed was changed to the unbalance coaxial feed, hence the antenna became a multiband microstrip patch antenna. For better result of the return loss and frequency, some slots were added to the microstrip patch antenna and the designed were compared and analyzed. The performance of the antenna was studied in terms of return loss, radiation pattern and half-power beam width (HPBW).
