Abstract

Abstract: A Compact antenna applicable for wireless communication fields like Long Term Evolution (LTE) frequency division duplex (FDD) Downlink Communication (1850‐1910 MHz Canada, Latin America), Worldwide Interoperability for Microwave Access (WiMAX) and Wireless local area network (WLAN) is proposed. The antenna structure is based on 1 outer ring resonators. Here, directly fed through the patch the stepped impedance transmission line with an optimized electromagnetic coupling outer ring. The proposed design operates in the lower frequency band from 1.79 to 1.94 GHz with 1.86 GHz center frequency and in the higher frequency band form 4.69 to 5.27 GHz. The compact antenna return loss is good agreement between simulated and measured results. The antenna gain value are 0.8 dBi at 1.86 GHz, 1.1 dBi at 4.75 GHz, 3.84 dBi at 4.97 GHz, and 2.64 dBi at 5.19 GHz. Moreover multi‐directional radiation to unidirectional radiation flow at the horizontal plane and vertical plane. A unidirectional radiation patterns based compact antenna utilized for wireless communication applications.
