A dual-UWB rotation independent clock antenna for WLAN applications

Abstract

The following paper presents a dual-UWB rotation independent clock antenna for WLAN applications. The antenna resonates at a frequency of 4GHz and at WLAN frequency of 5.2GHz with return losses of 24.31dB and 19.31dB respectively with an overall gain of 1.92dBi. A parametric study of the hour hand at different angles in the clock has been carried out so as to ensure the stable working of the antenna and to ensure that it is truly rotation independent. The clock antenna occupies two frequency bands from 3.66GHZ to 4.64GHz with bandwidth of 980MHz and from 4.89GHz to 5.5GHz with a bandwidth of 610MHz respectively.
