“…The work depicted in [16] is a slot antenna loaded with parasitic patches to obtain a maximum usable CP bandwidth. An inclined FDGS has been discussed in [17] and [15]; the fractal DGS is achieved in the ground plane inclined along the diagonal axis. The work in [18] gives a detailed understanding of the fractal structure used in the paper with a square patch.…”

A triangle-shaped proximity-fed circularly polarized antenna with a modified fractal ground structure is introduced in this paper. The antenna's ground plane is employed with a fractal-shaped corporate feed type cut, which helps produce the circular polarization. The proximity feed is offset from the center to generate the orthogonal modes; furthermore, the fractal modified ground aids in enhancing the axial ratio bandwidth. Different iterations of the basic fractal unit improve the polarization purity and axial ratio bandwidth. The experimental results of the designed antenna reflection coefficients below 10 dB at 2.5 GHz show an impedance bandwidth of 260 MHz (2.35 GHz to 2.61 GHz) and axial ratio bandwidth of 120 MHz (2.48 GHz to 2.60 GHz). The simulated and measured results show a good agreement.

“…Compactness followed by multiband operation of CP antenna has been an inspiration for various researchers in wireless communication systems. Various antennas such as slot antenna [1][2][3][4][5], fractal antenna [6][7][8], monopole antenna [9,10] have been extensively designed to obtain multiband. The use of annular ring antennas [11][12][13] has also become a very promising applicant for multiband applications because of their simple structure and design flexibility in obtaining miniaturization.…”

A triple-frequency operated concentric annular ring microstrip antenna which is single fed is presented. The proposed antenna with three concentric annular rings and two symmetrical notches on its outer ring and having a cross slot in its ground surface shows triple band at resonance frequency 1.22760, 1.57542, and 2.18 GHz, respectively. At the first two bands (GPS L2 and GPS L1), circular polarization characteristic is observed and the third band observes linear polarization finding its application in Universal Mobile Telecommunication System (UMTS). The complete dimension of the antenna designed and fabricated is only 51.6 × 51.6 × 1.6 mm3. Experimental results depict the proposed antenna gain of 3.31, 3.55, and 3.50 dBi in three bands, respectively, and closely matches with the theoretical results.
