“…Lots of circularly polarized microstrip antennas using fractal shapes have been proposed in [20–25]. A circularly polarized single feed Minkowski fractal boundary microstrip antenna is proposed in [20], it shows the good circular polarization by changing the fractal boundary dimension in both the directions of the antenna.…”

“…The CP radiation and reduction in the size of the designed antenna [24] are obtained by introducing two asymmetric Koch fractal geometries on x - and y -plane of the square radiator. A single-feed circularly polarized Flared-U-type fractal boundary microstrip antenna has been presented in [25]. By interchanging the edges of a square path [25] with asymmetrical Flared-U-type fractal curves in two perpendicular directions, two degenerated orthogonal modes are generated for CP radiation.…”

Design of single-feed circularly polarized (CP) microstrip antenna is proposed in this article. The design employs the concept of E-shape patch with inclined fractal defected ground structure (IFDGS), which can improve the impedance bandwidth, gain, and axial ratio (AR) bandwidth. The excellent enhanced impedance bandwidth, axial ratio bandwidth, and gain are achieved by an inclined E-shaped fractal etched on the ground plane. The parameter studies of the E-shaped IFDGS are given to illustrate the way to obtain CP radiation. The third iterative IFDGS is fabricated on easily available FR4 substrate with a size of 0.494 λ0 × 0.494 λ0 × 0.019 λ0 (λ0 is the wavelength in free space at 3.624 GHz). The measured results verify the simulated results and show good agreement. The proposed antenna shows an impedance bandwidth of 12.7% at a centre frequency of 3.47 GHz and 3-dB AR bandwidth for this band is 2.39% at a centre frequency of 3.626 GHz. The measured peak gain for the proposed antenna is found as 8.1 dBi. The proposed antenna can be suitable for mobile WIMAX operation (IEEE 802.16e-2005 standard), wireless communication in CA-band and FCC.

“…Fractal geometry structures meet the compact size and circular polarization radiation pattern for antennas at the same time. Many research works discussed using different types of fractal geometry in designing antennas for various communication applications have been reported in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

“…The circular polarization in this antenna is obtained by a corner truncated off its square patch. A compact antenna in [10] is designed by adding flared-U-type asymmetrical fractals to generate two orthogonal modes for circular polarization emission. A fractal flared-U-type structure replaces the square patch's edge for this antenna, and then the indentation parameters of the fractal boundary curves are optimized.…”

The polarization of the received signals can be effectively matched regardless of the orientation of the receiving antenna using circularly polarized antennas. A compact printed monopole antenna with a circular ring patch is presented in this paper. The proposed antenna will be able to provide two polarization states: linear and circular. The employment of a modified Minkowski fractal with 1st iteration construction on an open circular ring supports a circularly polarized band having a center frequency of 1.812 GHz and fractional bandwidth (FBW) of 20.033%. The upper band is achieved with a linearly polarized wave having a center frequency of 3.386 GHz and a fractional bandwidth of 11.399%. The proposed antenna is fed by an ungrounded co-planar waveguide (UCPW), enhanced with an impedance transformer to match at 50 Ohms with the characteristic impedance. The ground planes around the feed line are defected by ground structures to improve the antenna gain. The fabrication and measurement of the proposed antenna prototype are presented to validate the theoretical results. Measured results support the theoretical findings well.
