| Popis: | A novel ultra high frequency (UHF) broadband polygonal monopole antenna with a notch is presented. The antenna is a wineglass-shaped geometry near two pairs of long-horn-shaped coupling elements located on the top and bottom surfaces to cover the band of 700 MHz–1.3 GHz with the size of 150 × 100 × 1.2 mm. The notch filtering is achieved at 900 MHz by using the open-terminated stub of a novel composite right/left handed transmission-line phase shifter. The phase shifter is 12 mm as 0.07 × λg. The validity of the proposed scheme is verified by designing and comparing the wide-band antenna with different notch-making approaches through electromagnetic simulation, fabrication and measurement. The simulated and measured results show high degrees of agreement. The suggested antenna is shown to be useful for UHF-band applications with a stopband at 900 MHz to avoid potential interference from the GSM-E service, Z-wave communication and UHF radio-frequency identification tag frequencies. |
