ABSTRACT
For an insight into a smart green environment, this chapter introduces a novel patch array antenna, which facilitates multiple applications such as mobile data communications to vehicles, machines, smart objects, and sensors, and manages a large number of users to account for future traffic growth. This radiating patch element combines a simple pentagonal slotted patch antenna with a single layer, which is designed to accomplish various resonant bands. The antenna and array components are fed by an input line feed network. To satisfy low-cost criteria, structures are realized using the high-frequency structure simulator electromagnetic 3D simulation tool and fabricated. For diverse bands of single elements, 1 × 2 linear arrays with proper planned transformation, sufficient impedance matching is desired. In comparison with current designs, better impedance bandwidths, modest gain, and better radiating efficiencies result from the analyzed configurations. Therefore, better peak antenna gains of 5, 6, and 9 dBi for multiple resonating frequencies of 2.4, 3.5, and 5.8 GHz respectively are achieved from a smart pentagon-shaped array antenna.
