This paper proposes a compact microstrip patch antenna for operating in 2.4 GHz ISM and 3.5 GHz WiMAX bands with circularly polarized (CP) radiation. The CP radiation in dual-bands is a result of two multilayered truncated corner stacked square patches, while the reactive impedance surface (RIS) is used for antenna size miniaturization for the lower operating frequency band. Since the overall lateral antenna dimensions are controlled by the lower frequency band (higher wavelength), reducing the electrical size of the antenna for lower band results in overall smaller antenna dimensions. The measured 3-dB axial ratio bandwidths of the in-house fabricated antenna prototype are 6.1% (2.40–2.55 GHz) for the lower band and 5.7% (3.40–3.60 GHz) for the upper band, while the 10-dBS11bandwidths for the two bands are 8.1% (2.39–2.59 GHz) and 6.9% (3.38–3.62 GHz), respectively. The maximum gain at boresight for the lower band is 2.93 dBic at 2.5 GHz, while the gain for the upper band is 6.26 d...

GPS, Satellite phones, requires broadband, miniature size and circularly polarized antennas. Microstrip antennas have inherently narrow bandwidth, hence demanded enhanced bandwidth and size reduction. The present paper discusses the design of wideband compact and circular polarised MSA. The bandwidth of proposed antenna is enhanced by using EC stacked patch antenna. The proposed antenna has 3 dB AR BW of 13.62 % and impedance BW (VSWR< 2) of 19.71%. It achieves a significant amount of size reduction by loading cross slots on radiating patch. The paper also analyzes different simulated designs in terms of VSWR, AR, Impedance, Gain.

A Review Paper on Circularly Polarized Microstrip Patch Antenna
Abstract— In this paper description of microstrip patch antenna is presented, along with the use of circular polarization and cavity to improve basic antenna characteristics. To achieve polarization matching between transmitting and receiving antenna use of circularly polarized antenna is an effective solution. Use of cavity in this antenna helps in suppressing surface waves and increases bandwidth of the antenna.
Design and Investigation of Circular Polarized Rectangular Patch Antenna
Microstrip patch antennas represent one family of compact antennas that offer a conformal nature and the capability of ready integration with communication system's printed circuitry. In this project, a 2.4 GHz circular polarization microstrip antenna is designed, constructed and measured. The microstrip antenna chose is a dual –fed circular polarized microstrip antenna. The antenna consists of rectangular patch and 3 dB hybrid. The dual – fed circular polarized microstrip antenna is etched on a FR4 with dielectric substrate of 4.5 with the height of 1.6 mm. Circular polarization is obtained when two orthogonal modes are equally excited with 90° phase difference between them. Circular polarization is important because regardless of the receiver orientation, it will always able receiving a component of the signal. This is due to the resulting wave having an angular variation.

This study introduces a new design of dual-band circular polarized (CP) microstrip antenna for ISM band applications (2.45 GHz and 5.8 GHz). The proposed dualband CP microstrip antenna with compact design has achieved design intention of having return loss of < −10 dB and axial ratio of < 3 dB for both frequencies of 2.45 GHz and 5.8 GHz. The antenna has been successfully designed, fabricated, simulated, and measured and it shows the advantages of good dual-band and CP performances. Thus, the obtained results confirm satisfactory performance and good agreement.

Microstrip line feed is used to energize the patch. CST microwave studio softwareis used to simulate the antenna design. Dual resonant frequencies are obtained by inserting a slot in patch. Resonant frequencies are obtained at 2.22GHz and 2.9GHz showing return loss of-18dB. Circular polarization is achieved by energizing the patch at two adjacent edges through a power divider. Axial ratios obtained at these frequencies are below the practical limit of 3dB.
Design and Analysis of Circular Slotted Microstrip Patch Antenna
International Journal of Electronics and Telecommunications, 2019
This paper presents a novel complementary CPWfed slotted microstrip patch antenna for operation at 2.4 GHz, 5.2 GHz and 6.3 GHz frequencies. The primary structure consists of the complementary split ring resonator slots on a patch and the design is fabricated on FR-4 epoxy substrate with substrate thickness of 1.6 mm. The described structure lacks the presence of a ground plane and makes use of a number of circular complementary SRRs along with rectangular slots on the radiating patch. The structure provides a wide bandwidth of around 390 MHz, 470 MHz and 600 MHz at the three bands with return losses of -11.5 dB, -24.3996dB and -24.4226 dB, respectively. The inclusion of the rectangular slots in the CSRR based slot antenna with stairecase structure improved the performance with respect to return loss.
