“…The printed slot antennas (PSAs) are also popular as planar antenna for broadband CP, [11,12,13,14,15,16,17]. In this letter, the high performance of the proposed PMA is proven by comparing it with some PMAs and PSAs reported in the literatures.…”

In this letter, a compact and broadband printed monopole antenna for circular polarization is proposed. In order to reduce the antenna size and achieve the circular polarization, the ground plane is combined by two elliptical shaped conductors with different size, and the antenna is designed asymmetrically to the microstrip line. The simulated and measured bandwidth of the 10dB-return loss with a 3dB-axial ratio is 57.9% (2.65GHz-4.81GHz) and 52.0% (2.45GHz-4.17GHz). The size of the antenna is 0.178λc 2 (λc is a wavelength in free space at the center frequency).

“…Also, CP overcomes phase problems in a multipath fading channel environment. This includes deadspots, decreased throughput, and reduced overall performance [13]. Additionally, compared to other polarizations, CP is more resistant to signal degradation due to extreme weather conditions [14,15].…”

Circular polarized (CP) antennas are well suited for long-distance transmission attainment. In order to be adaptable for beyond 5G communication, a detailed and systematic investigation of their important conventional features is required for expected enhancements. The existing designs employing millimeter wave, microwave, and ultra-wideband (UWB) frequencies form the elementary platform for future studies. The 3.4-3.8 GHz frequency band has been identified

Utilizing perturbations in the forms of feed lines [5]- [7], slot structures [8]- [10] and array configurations [11], [12] have also been proposed. Most of these designs are achieved by full-wave simulation and optimization based on engineering experience and intuition with little physical insight.…”

This paper presents the design process of a clock-shaped broadband circular polarized (CP) antenna based on Characteristic Mode Analysis (CMA). It is composed of a circular ring, two microstrip lines approximately perpendicular to each other, and 50-improved coplanar waveguide (CPW). The two microstrip lines are introduced in the X and Y directions, respectively, to break the symmetry for CP operation. Different from the conventional method in which the operation is verified by the simulated surface current distribution, CMA provides physical insight into different modes of the antenna and reveals the mechanism of radiating CP wave. Mode currents and characteristic fields of the selected modes are studied for AR bandwidth enhancement. An improved double-sided printed CPW is introduced to excite the desired modes and achieve wideband impedance matching. To validate the proposed concept, a prototype with a compact size of 0.29λ L × 0.29λ L × 0.013λ L (λ L corresponding to the maximum operation frequency) is fabricated and measured. The measured −10 dB impedance bandwidth and 3 dB AR bandwidth are 84.6% from 2.38 GHz to 5.8 GHz and 43.4% from 2.4 GHz to 3.73 GHz, respectively. The overlapping operating bandwidth can cover the ISM band, the TD-LTE band, and the WiMAX band. Besides, the proposed antenna has a stable radiation pattern over the operating band. INDEX TERMS Broadband antennas, characteristic mode analysis (CMA), circular polarization (CP), co-planar waveguide (CPW).
