“…The radiation pattern of a single-printed dipole antenna is typically asymmetrical, which causes the beam scanning range to present asymmetrically, making it difficult to use for two-dimensional phased array antennas [10][11][12][13]. Metal cavity-backed antenna structures, or Yagi-Uda antenna structures with multiple directors, are used to increase the gain and symmetricity of the radiation patterns [14][15][16][17][18][19][20][21][22]. Metal cavity-backed antennas have similar half-power beamwidths (HPBWs) in the E-and H-planes of their radiation pattern.…”

This paper investigated the characteristics of series-fed angled dipole antennas as the number of dipoles increased from one to two, four, and eight. A parallel strip line printed on both sides of the substrate was used to connect angled printed dipoles of the same size in a series with equal spacing. As expected, although the gain increased as the number of dipoles increased, the impedance and gain bandwidths decreased. In addition, as the number of dipoles increased, the half-power beamwidth (HPBW) differences between the xz- and yzplanes decreased and the radiation pattern of the xz-plane became more symmetric. Antennas with one, two, four, and eight-dipole elements in a series were designed, and their peak gains were 5.0 dBi, 7.2 dBi, 9.4 dBi, and 10.4 dBi, respectively. The differences between the xz- and yz-plane HPBWs of the four antennas were 160.4°, 41.7°, 14.2°, and 5.3°, respectively. As the number of dipoles in the antenna increased, the differences between the HPBWs in the xz- and yz-planes decreased.

“…A typical microstrip-to-slotline transition used a cross junction to magnetically couple between the two lines: i.e., using a perpendicularly crossing structure with quarter-wave stubs on both lines [1][2][3]. The resonating structure caused frequency bandwidth limitation, and efforts have been made to minimize the structure or widen the frequency bandwidth [4][5][6][7][8][9][10]. By using a multi-arm single junction or a strip-slot double junction structure, the transition bandwidth could be widened, but the structure was very sensitive to fabrication tolerances and needed high-permittivity substrates to reduce the parasitic capacitance [6,7].…”

“…By using a multi-arm single junction or a strip-slot double junction structure, the transition bandwidth could be widened, but the structure was very sensitive to fabrication tolerances and needed high-permittivity substrates to reduce the parasitic capacitance [6,7]. In addition, for use as a compact balun of an antenna, several transition designs were attempted with a slotted microstrip structure or a novel shape stub [9,10]. Another type of transition was designed with bifurcated microstrip lines, and used a half-wave-delayed microstrip line to feed the slotline [11].…”

Analysis and design of an ultra-wideband microstrip-to-slotline transition on a low permittivity substrate is presented. Cross-sectional structures along the proposed transition are analyzed using conformal mapping assuming quasi-TEM modes, attaining one analytical line impedance formula with varying design parameters. Although the slotline is a non-TEM transmission line, the transitional structures are configured to have quasi-TEM modes before forming into the slotline. The line impedance is optimally tapered using the Klopfenstein taper, and the electric field shapes are smoothly transformed from microstrip line to slotline. The analytical formula is accurate within 5% difference, and the final transition configuration can be designed without parameter tuning. The implemented microstrip-to-slotline transition possesses insertion loss of less than 1.5 dB per transition and return loss of more than 10 dB from 4.4 to over 40 GHz.
