Enhanced-Gain Low Cost Television White Space Z Antenna Using a Thick Diameter Copper Wire

摘要

Television White Space is gaining attention as a possible means to help address essential factors associated with ubiquitous availability and adoption of broadband internet. This paper presents a novel enhanced-Gain low Cost Television White Space (TVWS) Z antenna for broadband internet access. The antenna performance is demonstrated in the UHF band. Design of a low cost Television White space Z antenna for the client was previously done and it was deducted that it is possible to assess the spectrum usage using low cost equipment. In this paper, the design aspects and measured results of an enhanced-gain low cost Television White Space Z antenna using a thick diameter copper are presented. ANSYS HFSS software was used and this is the Industry standard tool for simulating 3-D, full-wave electromagnetic fields. In this paper, the gain of the antenna has improved by 4.993dB and the bandwidth has increased from 13MHz to 60MHz as a result of using the thick diameter copper wire with much more lengthened sides and axis.
