In this article, wideband circularly polarized monopole antennas with multiresonating frequencies are presented for Bluetooth, WLAN, WiMAX, and X‐band applications. The designed antennas have dimensions of 50 × 35 × 1.6 mm3. Two different substrates (FR4‐epoxy and PTFE) are used for fabricating the antennas. The antennas consist of corner truncated I‐shaped and C‐shaped strips excited by a 50 Ω microstrip feed line. The parametric analyses are performed with the help of Ansoft HFSS V.11 EM simulator. Both antennas have been fabricated and measured. The measured percentage bandwidth of the antenna made by FR4 substrate is 31.32% (centered at 1.66 GHz), and 64.85% (centered at 5.69 GHz). The percentage bandwidth of antenna made by PTFE substrate is 20.57% (centered 2.43 GHz) and 68.74% (centered at 7.39 GHz). In addition to that, there exists 3 dB AR bandwidth for LHCP of about 1050 MHz for 5.2 GHz WLAN‐band. The reflection coefficient, radiation patterns, and the gains of both the antennas are studied in detail. It is found that the measured and simulated results are in good agreement.

“…Based on the above analysis, it can be summarized that an antenna etched with CSRR performs excellently despite being small in size and containing a simple structure. Furthermore, we compared the dual-band antenna designed in this work with other literature [8,14,22] in terms of size, number of resonance peaks, operating frequency bands, and peak gain, as listed in Table 2. It is observed that, in other works, multi-band antenna are larger, while small size antenna operate at single-band.…”

“…Microstrip patch antenna (MPA) are extensively used due to their advantages of small size, simple structure, low cost, and ease of integration [6,7]. Many methods have been studied to obtain multi-band antenna, such as coupling feed technologies [8], slot-loaded technologies [9], and reconfigurable technologies [10,11]. Unfortunately, these methods require complex calculation, and the antenna structures are difficult to manufacture.…”

A dual-band microstrip patch antenna (MPA) based on a polarization conversion metasurface structure was designed. By etching the complementary split ring resonator (CSRR) on the ground plane, a new resonance frequency is generated. The proposed antenna is obtained through optimizing the structural parameters of CSRR. Compared with the antenna without CSRR, the return loss of the proposed antenna increases by ∼40% at the original resonance frequency. The measured results are similar to the simulated results, verifying the reliability of the antenna. This work introduces a new way of designing multi-band antenna.

“…In Reference 14, a multilayer patch antenna is proposed to achieve triple band CP behavior. All the above discussed triple band CP antennas are either having narrower axial ratio bandwidth 7,14,[16][17][18] or having larger physical dimension. 8,14,15,17 A dual band CP antenna is recently reported in Reference 19 with wide axial ratio bandwidth, but it is having larger size.…”

A compact planar triple band circularly polarized (CP) antenna loaded with parasitic elements is proposed for wireless applications. For achieving circular polarization 2 inverted L-shaped strips are added to the longer arm of dual band monopole and ground plane. A rectangular patch and a U shaped radiator are added to increase the impedance bandwidth as well as polarization purity. Electrical size of the antenna is 0.32λ × 0.32λ, where λ is the free space wavelength at its lowest CP frequency that is, 2.4 GHz. The structure shows an impedance bandwidths (│S 11 │ ≤ -10 dB) of 870 MHz (1.83-2.7 GHz), 1.17 . The 3-dB axial ratio bandwidths of the proposed structure are 12.2%, 5.3%, and 4.28% at 2.375, 3.47, and 4.9 GHz of center frequencies respectively. The proposed structure is fabricated and its parameters are measured. Measured results nearly match with the simulated results and it shows satisfactory gain in all the three operating CP bands.
