“…The other is a circularly-polarized squared microstrip antenna (DPMA) (see Fig. 1(a)) fed with an offset coaxial probe [20]. The feeders were designed using the Arlon Diclad 880 dielectric substrate (with a relative permittivity of 2.17, a loss tangent of 0.0009 and an h = 1.52 mm thickness).…”

A hemispherical dielectric lens antenna is proposed to provide beam-steering for communication networks operating in Xband. Two different printed antennas are simultaneously used to guarantee high performance and diversity of applications, one a wideband linear polarized antenna, and the other a narrowband circular polarized antenna. To ensure this, the design relies on adding printed angled feeders correctly positioned in relation to the center of a homogeneous dielectric lens. A prototype was simulated, fabricated and tested. The measured results show that the antenna is capable of operating from 8.0 GHz to 12 GHz (gain of 14.2 dBi) or 9.5 GHz to 10 GHz (gain of 17.52 dBi).

“…An attempt was made to increase the bandwidth by using slot antennas. The shapes of these slots are different, which can produce distinct performances [6]. Radiation patches are E-shaped, H-shaped, E-H-shaped, W-shaped, U-shaped, etc., all of which show good performance when widening the bandwidth [7][8][9][10].…”

This paper proposes a compact double-layer microstrip patch antenna with a wide bandwidth of 4.83–6.1 GHz and a gain reaching 4.7 dBi. By folding its mirror image through the electric field symmetry principle of the microstrip antenna, its electrical properties are maintained, and the physical size is halved to the compact size of only 25 × 40 mm2. The proposed antenna has the radiation characteristics of a planar inverted-F antenna (PIFA), which can generate the first resonant frequency and realize omnidirectional radiation characteristics. By coupling and feeding the upper patch, the second resonant frequency of the proposed antenna is produced and the directional radiation characteristics of the microstrip patch antenna can be achieved. The consistency of the results between the simulation and test indicates that the proposed antenna design is an ideal potential choice for home wireless local area network (WLAN) communication.
