“…Instead of bending the probe in L shape, a printed strip is used [14] (Jongkuk park,2004).A dual feed type suspended microstrip antenna is proposed for wideband and circular polarization. The aperture and L probe feeds are used for getting orthogonal polarization (Lau and Luk, 2005) [15]. It is inferred from this paper that dual feed method for getting orthogonal polarization is providing wide axial ratio bandwidth than single feed CP techniques.…”

In this paper, broadband and circular polarization techniques of Microstrip antenna (MSA) are studied. Microstrip antennas are suitable candidate for modern wireless communication. It possesses the advantages such as light weight, low cost and easy to fabricate, but they are inherence of bandwidth due to resonant nature. Several researchers attempted to overcome the above limitation. Also, MSA radiates naturally linearly polarized waves. Modern wireless communication requires circular polarization and wide bandwidth. In this context, several literature papers are available. The objective of the paper is to comprehensively study popular circular polarization and broadband techniques in MSA and sharing the knowledge to the new researchers in this field. Also, a design example is illustrated for broadband circularly polarized microstrip antenna

A dual-band dual-circularly polarized patch antenna which is excited by two L-probes and fed by substrate integrated coaxial line (SICL) branch-line coupler is designed, fabricated, and measured. Simulation and measurement results show that, considering reflection coefficient, gain, and axial-ratio (AR) together, the bandwidths are 10% and 4%, and the antenna gains are 7 dBi and 8.2 dBi, respectively, at 1.6 GHz and 2.5 GHz bands.

“…It has found wide applications in the consumer products due to its good characteristics and low cost, which has been comprehensively reported in several studies [1][2][3]. On the other hand, the circular polarization (CP) antennas [4][5][6][7][8][9][10][11][12][13][14] have become more and more popular not only in the satellite communications but also in the territorial communications. For example, CP antennas can be used in radio frequency identification (RFID) systems and global positioning system (GPS) to reduce power loss due to polarization mismatch.…”

“…The other is that the phase difference between two orthogonal modes is 90 • . A well known and often employed technique to generate a CP wave is to choose a suitable asymmetric feed-point on the asymmetric microstrip patch, thus resulting in two degenerated modes and good impedance matching [4,5]. However, it is impossible for a thin dipole antenna to radiate a CP wave because only one directional current exists on the dipole surface.…”

Abstract-A coplanar-strip dipole antenna with two enhanced features is presented for broadband circular polarization (CP) operation. The first feature of the proposed antenna is the replacement of a conventional thin dipole by a wide strip, resulting in two degenerated orthogonal modes to make CP operation possible. The second one is the use of two coplanar strips instead of two non-coplanar ones, thereby giving rise to the advantages of easy implement, good impedance matching, and wide axial ratio (AR) bandwidth. Two examples are given, one for the lower band around 1.8 GHz and the other for the ultra-wideband (UWB). For the lower band, the measured −10 dB return loss (RL) bandwidth is 119% (0.74 to 2.93 GHz), and the measured 3 dB AR bandwidth is 50% (1.45 to 2.41 GHz). As for UWB, the measured RL is below −10 dB between 2.1 to 10.1 GHz, and the measured AR is below 5 dB between 4.1 to 7.75 GHz.
