The array antenna consists of two single patches on the same substrate.In this array antenna the gap between the antennas is 80 mm (Table 1; Figures 4 and 5).Antenna array is mainly used to improve the antenna parameters .
By using T-power divider circuit micro-strip patch antenna array with same dimensions is designed on a same substrate.
Microstrip patch antenna array is designed to increase the gain .
antenna is simulated using the Electromagnetic simulator, IE3D.
By using these dimensions a single micro-strip patch antenna is designed .
Patch may be of any shape like square, rectangular, circular, elliptical, triangular or any other configuration.
But configurations which are mostly used are rectangular and circular .It provides a diversity gain in multipath signal reception.They enable array signal processing and overcome the disadvantages of patch antennas .DGS have relocated frequency which makes antenna small.It also reduces the mutual coupling in antenna arrays (Figures 2-4).The antenna design is made on a FR4 substrate having dielectric constant of 4.4 and height of the dielectric substrate is chosen as 1.5 mm.50 Ω micro-strip feed lines are used to feed the radiating patch .Using the dimensional equations, the dimensions of the this antennas are the length of the ground plane Lg is 120 mm, width of the ground plane Wg is 50 mm.Length of the feed Lf is 9 mm and width of the feed Wf is 2 mm.Antenna design A proposed micro-strip patch antenna array is shown in Figure 5.The proposed antenna array consists on a single substrate .
