[en] This paper reveals a patch antenna with a large bandwidth of 34% and a high gain of 8 dBi in the frequency range from 10.1 to 14.2 GHz. The patch antenna is a four layer design comprising of a superstrate dielectric layer of εr 10.2 on top of a metal layer with six small simply designed parasitic H-shaped elements, which are optimized using CST Microwave Studio. The six H-shaped parasitic elements are centrally located on the metal layer. On the same layer, the antenna is fed through a coupled feedline so as to reduce mutual coupling and the antenna is thus a perfect candidate to preserve its wideband feature in an antenna array. Right underneath the metal layer is the substrate dielectric layer of εr 2.2 with two strategically placed slots underneath the metal layer in order to decrease the back radiation of the H-shaped parasitic elements. The whole design is terminated with a final metal layer to act as a conductor backed antenna to push most radiation out. The final antenna occupies a volume of 25 mm x 25 mm x 2.56 mm. The design has a high gain of 8 dBi in both the φ = 0° plane and the φ = 90° plane with a large beamwidth of 77° in the φ = 0° plane and 83° in the φ = 90° plane in the farfield.
