Summary: This paper proposes a miniaturized MIMO antenna array based on half-mode substrate integrated waveguide (HMSIW). The operating bandwidth is widened by introducing quarter-mode on the conventional HMSIW, and the array size is further reduced by orthogonally arranging the four antenna elements using quasi-electric wall characteristics of metal via. The decoupling structure of composite neutralization lines (NLs) is used to improve the isolation of the MIMO antenna array. The fabricated and implemented 2x2 MIMO antenna array shows good agreement between simulated and measured results, with high gain and low mutual coupling levels.

Summary: This paper proposes a directivity-enhanced planar slot antenna (PSA) backed by substrate integrated waveguide (SIW) cavity to solve the problem of maximum gain direction bias. The reason for maximum gain direction bias is explained according to the radiation principle of slot antenna, and a solution is provided. The problem of frequency bias caused by changing the directivity is also explained by resonance modes and solved by introducing the metal via. An example with 5.8 GHz is given, which achieves a maximum gain of 5.28 dBi and a total thickness less than lambda/4. After structural optimization and measurement, the improved antenna achieves a maximum radiation direction of 0 degrees from the normal direction of the antenna surface, while maintaining the good radiation performance and small size of the traditional PSA backed by SIW cavity.

Summary: A synthesis method based on compression coefficients is proposed to enhance gain and suppress sidelobe levels of a high-order mode dipole. The method first utilizes designed compression coefficients to determine the current distribution of the dipole, generating a continuous source. Then, a pattern synthesis method is presented to calculate the compression coefficients and enhance gain with desired sidelobe levels. The proposed fifth-order mode dipole with a length of 1.5 wavelengths at 3.25 GHz achieves a gain of 6.6 dBi and an SLL of -13.3 dB, outperforming an array of three half-wave dipoles.

Summary: A multiple tri-beam low scanning loss millimeter-wave transmissive metasurface antenna is proposed for wide-angle coverage. The proposed metasurface combines the focusing phase and the periodic phase to achieve the desired aperture phase distribution.
