EE4101 Antenna Arrays 1 Introduction Antenna arrays are becoming increasingly important in wireless communications. Advantages of using antenna arrays: 1. They can provide the capability of a steerable beam (radiation direction change) as in smart antennas. 2. They can provide a high gain (array gain) by using simple antenna elements. 3. They provide a diversity gain in multipath signal reception. 4. They enable array signal processing. Hon Tat Hui 1 Antenna Arrays NUS/ECE EE4101

Arrays An array is a series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding an index to a unique identifier. That means that‚ for example‚ we can store 5 values of type int in an array without having to declare 5 different variables‚ each one with a different identifier. Instead of that‚ using an array we can store 5 different values of the same type‚ int for example‚ with a unique identifier. For example‚ an array to contain

a) Photovoltaic solar power systems are environmentally beneficial because they release no harmful pollutants or emissions such as CO2. These systems operate throughout the day‚ implying it is sunny‚ and do not rely greatly on other power sources to operate‚ thus there is less of a toll on the environment in terms of external resource usage. An environmental cost of photovoltaic systems is the manufacturing of these systems that uses energy and could possibly contribute to more atmospheric pollution

Parallel arrays and arrays of structures An array of structures are usually equivalent to parallel arrays of the components. For example‚ if each student record consists of an ID number and a GPA value‚ then a list of students can be represented as an array of structure: The same data can be stored as two arrays that "parallel" to each other‚ in the sense that the same index in them indicate data for the same student: Usually the first way is more natural and convenient.

SOLA3010 & SOLA9009 Low Energy Buildings and Photovoltaics Course Outline 6 Units of Credit (UOC) 4 contact hours per week Course Context and Description Building energy use comprises about 40% of the total electrical energy used in NSW. Since the advent of artificial heating and lighting methods and the modernist aesthetic‚ much of the traditional wisdom that informed climate-specific vernacular architecture has been abandoned. There is currently significant interest in reducing energy use in buildings

CheckPoint : Arrays and Versus Pointers Define the following and provide an example of each: * Pointer * Arrays Answer the following questions and provide an example of each: What is the difference between a one-dimensional and a two dimensional arrays? Arrays store items that have the same type of data type like a group of employees’ names and social security numbers for a team of 2000 personal. Pointer is a variable that greatly extends the power and flexibility of a program‚ each
