TLDR
A miniaturized triple band multi frequency antenna that mainly consists of a circular ring, U-shape-like slots on substrate, and a defected ground structure having L-shape and staircase like slots is presented.Abstract:
paper presents a miniaturized triple band multi frequency antenna. The proposed antenna can generate two separate impedance bandwidths to cover all the 2.4/5.2/5.8- GHz WLAN operating bands and the 2.5//5.5-GHz WiMAX bands. The proposed microstrip-fed antenna mainly consists of a circular ring, U-shape-like slots on substrate, and a defected ground structure having L-shape and staircase like slots. The design considerations for achieving broadband operation of the proposed Defected ground structure antenna are discussed, and theoretical results are presented. The antenna operates in two frequency bands, and impedance bandwidth of lower frequency band is 0.92 GHz from 2.37- 3.29 GHZ and upper frequency band is 2.57 GHz from 4.22- 6.29 GHz covering WLAN/WiMAX bands with a total bandwidth of 3.49 GHz. The overall size of the antenna is 22 mm × 36 mm × 1.6 mm including the finite ground CPW feeding mechanics. The parametric study is performed to understand the characteristics of the proposed antenna. Also, good antenna performances such as radiation patterns, current distribution, and efficiency and antenna gains over the operating bands have been observed. The antenna is simulated using IE3D software.read more
