—This paper presents a compact dual-band multiple input multiple output (MIMO) antenna with low mutual coupling, operating in the 2.4 GHz band (2.4–2.485 GHz) and 5.5 GHz band (5.15– 5.85 GHz). The proposed antenna system consists of two antenna elements located at the top two corners of FR4 substrate (PCB). Each element dimension is reduced substantially(More)
—A WLAN band notched compact ultra-wideband (UWB) microstrip monopole antenna with stepped geometry is proposed. A L-slot loaded modified mushroom type Electromagnetic Band Gap (EBG) is designed, analyzed and used to realize notched band characteristics for wireless local area network (WLAN) in the UWB frequency range. The proposed antenna having partial(More)
—A planar compact multiband monopole antenna is presented for ultra-slim mobile handset applications. The proposed antenna operates over 0.885 GHz–0.962 GHz and 1.69 GHz–3.8 GHz frequency bands with −6 dB impedance bandwidth that covers GSM900, GSM1800, GSM1900, UMTS, IMT2100, WLAN, WiMAX along with most of the higher LTE bands of modern mobile phone(More)
In this paper a simple, compact, and low cost ultrawideband (UWB) stepped monopole antenna with partial ground plane with wireless local-area network (WLAN) band notched characteristics is proposed. The band notch is created by modified mushroom type Electromagnetic Band Gap (EBG) structure with slotted patch and cylindrical via. The proposed antenna is(More)
This article presents an antenna with a compact planar inverted-F antenna (PIFA) structure and its multiple-input multiple-output (MIMO) applications for Long Term Evolution (LTE) and other wireless frequency band like Personal Communication Service (PCS1900) and Worldwide Interoperability for Microwave Access (WiMAX). The PIFA antenna designed to cover the(More)
