Summary: This paper presents a CPS line-fed series dipole array antenna for high-gain realization, where the gain increases as the number of dipoles is doubled, unlike conventional endfire arrays. A fabricated array antenna with 32 dipole elements achieved a gain of 17.4 dBi at 15 GHz center frequency.

Summary: A new low-profile method for improving the bidirectional gain of a dual-element folded dipole antenna (DFDA) is proposed. The method utilizes integrated parasitic elements to condition the surface current distribution while preserving the radiators. A middle layer consisting of metal strips embedded between the upper and lower surfaces of the dipole, called midstrips, is introduced to polarize the dipole currents. The presence of the midstrips polarizes the cross currents on the dipole surface, improving radiation-polarization purity and leading to a gain enhancement.

Summary: A trapped wave-based solution is proposed to design compact planar vertically polarized (VP) endfire antennas. By using a four-element series-fed magnetic dipole array with half wavelength interspacing in a dual-layer metasurface and loading shorting pin arrays at the metasurface edges, the VP radiation is achieved in a wide impedance band. Furthermore, the antenna profile can be further reduced by half based on the electric field distribution within the metasurface. A VP endfire antenna is designed and validated with a reflection bandwidth of 4.3-5.4 GHz, a peak gain of 9.8 dBi, and a low total profile of 0.065 lambda(0) (lambda(0) is the free-space wavelength at the center operation frequency). This antenna can be applied in wireless communication systems on or near the ground plane, such as car roof-mounted terminals for vehicle-to-road side unit/base station communication.

Summary: This article proposes a phased array antenna skin for conformally assembling scenarios and wide scanning applications. A planar inverted F antenna (PIFA) is used as the radiation element, which has a low profile and omnidirectional radiation pattern. The PIFA element is conformally assembled on the wing of an aircraft using composite material technology to provide load-bearing capability. The array also supports wide-angle beam scanning in both forward and backward regions, and experimental results agree well with simulation data.
