Abstract—This paper focused on the development of Microstrip Antenna Array, which operates at 28 GHz where this frequency suggested as operating frequency for 5th Generation mobile technology. The proposed antenna structure is constructed with a single patch located in an array configuration within one plane. The antenna is fed from the backside via a coaxial fed. Normally in array antenna technology, researchers use full ground plane approach in order to meet a good antenna performance. The development of proposed antenna involved simulation, optimization, fabrication and measurement to get the best antenna performance at desired frequency. Simulation and optimization phase was done using Computer Simulation Technology (CST) software, which has the capability of giving a better look on performance of antenna in simplest way.
