Comparison of inset-fed rectangular and E-shaped antenna arrays for LTE & Wi-Fi applications

Recently, long-term evolution (LTE) advanced has been dominated as the next-generation wireless communication standard, which is aimed at higher peak data rates, close to 4 Gb/s. This is accomplished by designing an antenna with better antenna parameters (gain, directivity etc.,) so that the signal-to-noise ratio can also be improved. The main objective of this paper is to get improved antenna parameters by comparing the rectangular and E-shaped antenna arrays, which are useful for LTE33-41 (1,900–2,690MHz), Bluetooth (2,400–2,483.5MHz), GPS (L1, L4), BDS (B1), GLONSS (L1), GALILEO (E1, E2), WLAN (802.11b/g/n: 2.4–2.48GHz) applications. Initially this paper is designed as a single microstrip patch antenna and after assessing the outcomes of parameters; it is then transformed into a 1×2 linear array and a 1×4 linear array. This transformation increases directivity, gain and better radiation pattern since the array of antenna gives better antenna parameters than single antenna. The Design and simulation of this rectangular and E-shaped antenna arrays are implemented at 2.4 GHz with 2.2 permittivity of RT Duroid using CST Microwave Studio. The rectangular array gives high gain and directivity than E-shaped array but E-shaped array is applicable to multiple tasks (it is resonated more than once) than rectangular array (single resonated antenna).
