“…This topology is expected to be very suitable in view of the specific features needed for the patch current amplitude and phase distributions: when the E-vector of the excitation field is parallel to the slotted side of the patch, the radiation field has predominantly a linear polarization. It is worth mentioning that, to the knowledge of the authors, no slotted strip-frame patches of this kind have ever been used in printed planar or cylindrical antennas [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. It is clearly shown in this paper that slotted strip-frame patches are effective for cylindrical microstrip antenna arrays (CMAAs) fed by a cylindrical microstrip line.…”

Abstract-A cylindrical microstrip array antenna with 5 pairs of coupled slotted strip framed patches is analyzed. The patches are proximity-fed by a cylindrical microstrip line. In order to extract the reflection coefficient from the standing wave pattern on the microstrip line, its length is about 5 wavelengths. To the best of the authors' knowledge proximity-fed cylindrical arrays have not been analyzed before using a rigorous MOM model that takes into account all electromagnetic couplings between patches and feeding line. The paper consists of three parts. The first part describes a plane wave excitation of the cylindrical microstrip structure. It introduces some innovating theoretical developments, like the improvement of the asymptote for the spectral Green's function and the explicit surface wave contribution. The second part calculates the radar cross section of the cylindrical microstrip structure with single and coupled slotted strip framed patches. The resonant frequencies, and the amplitude and phase of the current distribution are analysed. The third part describes a design for a proximity-fed array of 5 coupled slotted strip framed patches. It gives the reflection coefficient, current distribution on the patches, and radiation pattern. A very low level of cross polarization (< −40 dB) is achieved. It is shown that the resonant frequencies of the cylindrical array and its planar analogue lie very close to each other. This is due to the common nature of the low frequency slot resonance for the slotted strip framed patch.

“…Many researchers have made a lot of efforts on the development of dual-polarized antennas [2][3][4][5][6][7][8][9][10][11][12][13] and broadband base station antennas [8][9][10]. The dual-band dual-polarized antenna that proposed in [6] was formed by arc-probe-fed annular ring element and pairs of cross microstrip dipoles nested together, and achieved an impedance bandwidths of 17.4% (806 ∼ 960 MHz) for VSWR < 2 in the lower band and 23.7% (1710 ∼ 2170 MHz) in the upper band, respectively.…”

Abstract-A compact dual-band dual-polarized antenna is proposed in this paper. The two pair dipoles with strong end coupling are used for the lower frequency band, and cross-placed patch dipoles are used for the upper frequency band. The ends of the dipoles for lower frequency band are bent to increase the coupling between adjacent dipoles, which can benefit the compactness and bandwidth of the antenna. Breaches are introduced at the ends of the dipoles of the upper band, which also benefit the compactness and matching of the antenna. An antenna prototype was fabricated and measured. The measured results show that the antenna can cover from 790 MHz to 960 MHz (19.4%) for lower band and from 1710 MHz to 2170 MHz (23.7%) for upper band with VSWR < 1.5. It is expected to be a good candidate design for base station antennas.

“…It is precisely an original idea for the antenna operating in multi-beams or beam-scanning, although many investigators [14][15][16][17][18][19][20][21][22][23][24][25] have been working on the techniques for several years. The plasma antenna of beam-forming examined in this paper is composed of plasma elements as reflector (or scatterer to be more accurate) and additional omnidirectional radiation source.…”

Abstract-In this paper, a new plasma antenna of beam-forming is investigated based upon the interaction of plasma elements due to the incident electromagnetic wave. It presents a study of the multiple scattering from argon plasma cylinders rigorously applying boundary value method, grounded on the properties of electromagnetic wave transmitted in the argon plasma. Approximate expressions for the total radiation of plasma antenna in the far field are derived briefly. Such a novel plasma antenna of beam-forming, according to the research, exhibits interesting performance in terms of radiation efficiency, beam-forming and beam-scanning. Valid results are brought forth to demonstrate the capabilities of such antenna of two scales. Comparisons are given in detail as well.
