“…There are a number of effective ways to reduce the size of patch antennas: 1) increase electrical length by optimizing the shape of a patch; 2) use high-permittivity substrates; 3) introduce shorting pins at the edge of the patch or in the vicinity of a coaxial feed; and 4) a combination of these approaches. An -shaped patch antenna proposed by Palanisamy and Gary is one of the well-known choices for miniaturization of patch antennas by optimizing the shape [1]. The dimensions of the -shaped patch antenna are normally about a quarter waveguide wavelength square.…”

A thin-film superconducting meander patch antenna coupled by an H-shaped aperture is proposed. It is analyzed using a full wave electromagnetic simulator and the theory of cavity model for microstrip patch antennas. The meander patch was fabricated from a single-sided film of YBCO (YBa 2 Cu 3 O 7 ) on MgO with a typical transition temperature of 90 K. Simulated results are presented for return loss, radiation pattern, and efficiency and these are shown in good agreement with the results obtained from network analyzer measurements. An array of a number of elements is also proposed for wide-band operation.

“…Between these perturbations, the square and circular rings are well-known alternatives to obtain small patches when compared to the filled versions [4]. Other well documented geometries are the H-shaped and meander patches [5], [6]. One novel geometry is inspired in Manuscript fractal shapes.…”

A small H-shaped microstrip patch antenna (MPA) with enhanced bandwidth is presented. The H-shaped antenna is first studied by a transmission line model and then is fully analyzed with a MoM code. A stacked patch configuration is proposed to increase the narrow bandwidth, radiation efficiency and directivity. The stacked H-shaped MPA is studied using Chu's fundamental limit for electrically small antennas.Index Terms-H-shaped antennas, limit of Chu, microstrip antennas, small antennas, stacked patches.

“…The radiation model of the back-to-back antenna array is studied, and the directivity formula on main radiation plane is obtained. The H-shaped patch [17] antenna array has better omnidirectional radiation pattern than the rectangular patch antenna array. Ansoft HFSS is applied to design and simulate the antenna arrays for the purpose of optimizing the omnidirectional characteristic, drawing the better technical parameters.…”
