“…Likewise, devices receiving information from the satellites such as GPS are also equipped with CP antennas [17]. Nowadays, personal mobile devices such as WiFi modems and RFID systems have also started to use CP signal to enhance the wireless performance [18]. In general, for wireless devices that are under constant motion and operating in electromagnetically crude environments, CP antenna is the preferred choice.…”

“…On the other hand, circular polarization (CP) in antennas reduces the loss caused by multipath effects, between the transmitter and receiver antennas. The circular polarization (CP) antenna is attractive for portable wireless application such as Radio Frequency Identification (RFID) because of its low profile, small size, and light weight [6]. Receiving orthogonal signals is another benefit of a CP antenna which makes circular polarization important for communication systems [4][5][6].…”

Abstract-In this letter, a new model of antenna with Jerusalem crosses (JC) as fractal slots for circular polarization applications is designed. The proposed slot antenna has a fractal cross formation with four Jerusalem crosses (JC) to achieve wide bandwidth and a compact size as well as circular polarization. A T-shaped feed line is implemented in the proposed antenna for improving the bandwidth while the interaction of the feed line with cross-shaped slots makes circular polarization. The proposed antenna shows bi-directional pattern and bandwidth at 2.42-3.0 GHz with VSWR < 2, which can be used in WiFi and Bluetooth applications with a gain of 3.5 dBi. The proposed fractal antenna size is 40 × 40 mm, and it is designed and fabricated on an FR-4 low-cost substrate with thickness of 1.6 mm. It is simulated by HFSS full wave software. In addition, the experimental results are presented and compared with the simulation for VSWR, radiation pattern and axial ratio.

“…A wide variety of perturbation methods have been adopted in literature for designing a single feed circularly polarized microstrip antenna. One 'V' shaped slot embedded into a cross shaped rectangular patch antenna [2], square patch embedded with a cross slot and an L-shaped open-end microstrip line linked to a tag chip, terminated by a shorting pin on the other end and capacitively coupled to the patch [3], an arrowhead-shaped slot is embedded in the first quadrant along the diagonal axes of a square patch [4], a circular patch antenna with central elliptical slot [5], two stacked patches fed with an S-shaped impedance-matching network [6] are some of the distinct techniques employed to excite circularly polarized radiation.…”

Abstract-This paper presents a compact 2.45 GHz single feed directional circularly polarized (CP) microstrip antenna for radio frequency identification (RFID) applications. The proposed antenna comprises a dodecagonal microstrip patch embedded with an irregular polygonal slot, fabricated on an FR4 substrate. Two antennas, one with right-handed circular polarization (RHCP) and the other with left-handed circular polarization (LHCP), both resonating at a frequency of 2.45 GHz are presented. The measurement results show a 3 dB axial ratio bandwidth of 5.5%, a 10 dB impedance bandwidth of 5.7% for both the antennas, a peak gain of 4.82 dBi for RHCP antenna and 4.67 dBi for LHCP antenna. In addition, the antennas provide symmetrical patterns with 88 • half-power beam width. The overall size of the antenna is 50 mm × 50 mm × 1.6 mm and offers an area reduction of 21.17%.
