Design of Penta-Band Omnidirectional Slot Antenna With Slender Columnar Structure
清华大学冯正和教授团队的论文,发表于IEEE AP
In this paper, we have proposed a co-located and
folded slots antenna for multiband applications. The proposed
antenna consists of three radiating slots, arranged on a compact
square columnar structure. By properly tuning the dimensions
and the positions of the co-located slots, the proposed antenna
operates in penta-band, including DCS, PCS, UMTS, 2.5-GHz,
and 3.5-GHz WiMAX bands. Additionally, omnidirectional radiation
patterns are provided in the azimuthal plane for all the
operating bands. The overall volume of the proposed square
columnar antenna is only 50 10 10 mm , which is suited for
volume-limited systems. A prototype of the proposed antenna is
fabricated and tested, to validate the design idea. The measured
data, including S parameter, radiation pattern, and gain, agree
well with the simulation results.
