In this paper, a planar inverted miniaturized ultra high frequency E antenna, with high gain will be discussed. This paper will present the design of the microstrip antenna, its development and performance based on the measured results. The shape of the antenna is similar to the inverted alphabet E, which is why the antenna is referred as E antenna. The operating frequency of the antenna is 868 MHz. This antenna works on a phenomenon similar to that of a PIFA (planar inverted F antenna). The radiating part is shorted with the ground plane, to reduce the size of the antenna. The aim of this project was to make a small, compact, low cost planar antenna, which has a good gain and can be accommodated in small card shaped areas, for different compact wireless systems. E antenna can be considered as a miniaturized, low cost antenna model, suitable for many small wireless systems with a good gain and an omni-directional radiation pattern.
