“…The multiband circularly polarized microstrip antennas are popular choice among the present microstrip antennas as it has the advantages of better mobility, less transceiver loss caused by polarization mismatch, better weather penetration, and orientation independent receiver system than linearly polarized microstrip antennas. The several designs of stacked microstrip antenna to achieve dual circular polarization (CP) operation have recently been reported using dual‐feed branch line coupler, multilayer structure, T‐shape slits, dual‐feed, aperture coupled stacked patch. However, two CP bands are merged together by optimizing the feed location and substrate thickness between the stacked patches to obtain wideband CP microstrip antenna .…”

A novel quad‐band circularly polarized capacitive coupled stacked patch antenna with wideband characteristics is presented for C‐band applications (4–8GHz). In the proposed design, only two truncated patches with horizontal slits and inclined slot are stacked together to generate quad‐band circular polarization operation and broadband behavior. The proposed antenna has achieved a bandwidth of 55.46% in the frequency band of 4.97–8.49 GHz and the 3‐dB axial ratio bandwidths of 0.98%, 4.275%, 0.8869%, and 1.35% in four distinct bands of 5.1223–5.1729 GHz, 5.4710–5.7100 GHz, 6.2747–6.3306 GHz, and 7.6775–7.7822 GHz, respectively. The measured results show the good agreement with simulated results of the presented antenna and confirm the validity of design. The proposed antenna is useful for various C‐band applications. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2622–2628, 2015

“…The dual CP radiation is obtained by introducing a pair of stubs and ring slot. Several designs of stacked microstrip antenna to achieve dual CP operation have recently been reported [7][8][9][10][11][12]. In a stacked structure; the feed is connected to only one patch while patches on the other layers receive the excitation from the fed patch.…”

In this paper, a multiband circularly polarized capacitive coupled stacked microstrip antenna is proposed. The multiband circular polarization (CP) is achieved by corner truncation, embedding slits and inclined slots on a three layered antenna structure. The proposed antenna also shows wideband behavior with an impedance bandwidth of 52.13% in the frequency range of 4.85 GHz to 8.27 GHz, while 3 dB axial ratio bandwidths in five CP bands are 0.51%, 4.54%, 0.33%, 0.83% and 1.29% in the frequency range of 5.12 GHz to 5.15 GHz, 5.45 GHz to 5.70 GHz, 5.90 GHz to 5.92 GHz, 6.25 GHz to 6.31 GHz and 7.68 GHz to 7.78 GHz, respectively. The antenna prototype is fabricated, and simulated results as axial ratio, radiation pattern and the reflection coefficient are validated with measured result.

Abstract-In Chinese Compass Navigation Satellite System (CNSS for short), dual-band antennas are more attractive, because they can provide both navigation and communication services. In this paper, we present a dual-band dual-circular-polarized planar spiral-slot CNSS antenna. This antenna works at L band (1616 ± 5 MHz, left-handed circular polarization, LHCP) and S band (2492 ± 5 MHz, right-handed circular polarization, RHCP). Numerical results show that the impedance bandwidth (S 11 < −10 dB), 3 dB axial ratio bandwidth and antenna gain at L band are about 242 MHz, 79 MHz and 4.92 dB, respectively, while the simulated impedance bandwidth (S 11 < −10 dB), 3 dB axial ratio bandwidth and antenna gain at S band are about 180 MHz, 58 MHz and 5.25 dB, respectively. An experiment was carried out to verify our design. Measured results show that impedance bandwidth (S 11 < −10 dB) and 3 dB axial ratio bandwidth L band are about 300 MHz and 14 MHz, respectively, while the measured impedance bandwidth (S 11 < −10 dB) and 3 dB axial ratio bandwidth at S band are about 210 MHz, 10 MHz, respectively. The measured results basically agree with the simulated ones and meet the requirement of CNSS terminal antennas.
