“…Using 1 in 10 points, or even 1 in 15, will not affect the calculated frequencydomain response [17]. The only advantage of using many points is that the distance between points in the frequency domain is Y ( Z l 9 0) --,-y(w)lz,-z1] Y(z23 0) (12) or (19)…”

The finite-difference time-domain (FDTD) method is a widely used numerical technique for computer-aided design (CAD) of printed antennas and arrays. This technique can accurately predict performance characteristics of complex microstrip antennas, including the effects of parasitic elements and aperture-coupled feeds. In the case of arrays, mutual coupling effects between closely packed elements can also be modeled. This article will examine the advantages and limitations of the FDTD method for CAD of microstrip arrays. Calculated results are compared with experiment for a 3-patch coplanar parasitic patch array.

Abstract-The utility and attractiveness of microstrip antennas has made it ever more important to find ways to precisely determine the radiation patterns of these antennas. Taking benefit of the added processing power of today's computers, electromagnetic simulators are emerging to perform both planar and 3D analysis of high-frequency structures. One such tool studied was IE3D, which is a program that utilizes method of moment. This paper makes an investigation of the method used by the program, and then uses IE3D software to construct microstrip antennas and analyze the simulation results. The antenna offers good electrical performance and at the same time preserves the advantages of microstrip antennas such as small size, easy to manufacture as no lumped components are employed in the design and thus, is low cost; and most importantly, it serves multiple wireless applications.

“…Researchers have devised several methods to increase the bandwidth of Microstrip antenna in addition to the common techniques of increasing the patch height, decreasing substrate permittivity. This includes using a multilayer structure consisting of several parasitic elements with slightly different sizes above the driven element (a stacked patch antenna) [8], a planer patch antenna surrounding by closely spaced parasitic patches (a coplaner parasitic sub array) [9] or by implementing internal structures such as slots [10], [13]. The stacked patch antenna increases the thickness of the antenna while the coplanar increases the lateral size of the antenna.…”

This paper presents the design of a wideband microstrip patch antenna for LTE-A. The bandwidth of the conventional patch is enlarged by using etched slots at the antenna patch. The designed antenna has been fabricated by using thin film and photolithographic technique and has been measured by using the Vector Network Analyzer. The simulated and measured results were found to have good match with each other. Then, by using the designed single element antenna, a four-element MIMO antenna system has been built employing orthogonal polarization diversity. Isolation between the microstrip elements is increased by placing metal structure between antenna elements. For more isolation between antenna elements, Slotted Ground Plane SGP is utilized. It is found, by using commercial software CST Microwave Studio and measurement, that the designed planar MIMO antenna system has sufficiently high return loss and low mutual coupling at the required bandwidth of 70 MHz. It is found also that the developed antenna system meets the requirements for LTE-Advanced (2500-2570 MHz) band "CA-B7" as of today"s standard based on 36.101 Table 5.5-1 (March 2012) .
