A Textile Right Angle Slot Antenna with Dualband Circularly Polarization

In this paper, A Textile Right Angle Slot Antenna with Dual-band Circularly Polarization, the improved dual-band circularly polarized (CP) omni-directional based on the right-angle slot in textile is presented. This technique uses different slot sizes appropriately in various positions. The right-angle slot, which consists of the two smaller right-angle slots and two large right-angle slots, produces a circularly polarized (CP) and dual-band resonance. This paper presents an analysis of right-angle slot microstrip antennas to obtain dual-frequency, achieving ± 45 linear polarization in a slant. The presented textile right angle slot antenna covers the 2.45 GHz and 5.25 GHz frequency bands supporting the wireless local area network. A prototype of a model antenna and experiment is made. The measured results are shown to be reasonable for simulated results. Moreover, the antenna's maximum gain at 2.45 GHz and 5.25 GHz was around 5.2 dBi and 5.5 dBi, respectively.
