Antenna design for femtocell LTE at frequency 2.3 – 2.4 GHz

Abstract

In cellular networks, it is estimated that more than 50% calls and over 70% of data services occur indoors. Femtocells, also known as home base station, are cellular network access points that connect standard mobile devices to a mobile operator's network using residential Digital Subscriber Line (DSL), cable broadband connections, optical fibres or wireless last-mile technologies. This femtocell antenna is designed to work at frequency 2.3-2.4 GHz for VSWR <;2 and have 100 MHz Impedance bandwidth. From measurement of S11 parameter shows that the single element antenna has 320 MHZ impedance bandwidth which covers frequency 2.12-2.47 GHz.
