Abstract
An F-inverted compact antenna for ultra-low volume Wireless Sensor Networks is developed with a volume of 0.024λ×0.06λ×0.076λ, ground plane included, where λ is a resonating frequency of the antenna. The radiation efficiency attained is 48.53% and the peak gain is −1.38 dB. The antenna is easily scaled to higher operating frequencies up to 2500 MHz bands with comparable performance. The antenna successfully transmits and receives signals with tolerable errors. It includes a standard PCB board with dielectric block thereon and helically contoured antenna wound from a copper wire attached to the dielectric block and oriented with the helix axis parallel to the PCB. The antenna demonstrates omnidirectional radiation patterns and is highly integratable with WSN, specifically in Smart Dust sensors. The antenna balances the trade offs between performance and overall size and may be manufactured with the use of milling technique and laser cutters.
