“…Using high-quality-factor AlON transparent ceramics, the aesthetically decorative DRA exhibits a high radiation efficiency (Figure 9a) and low crosspolarization (Figure 8). In addition, when the proposed antenna and some previously reported 5 GHz Wi-Fi antennas are compared, 4,5,41,42 the proposed antenna exhibits not only a high radiation efficiency and low cross-polarization but also is an indoor aesthetically decorative Wi-Fi DRA that is designed to incorporate well into the concept of a smart home.…”

Transparent material has been widely used in product design and has seen a large increase in its use. In this paper, a kind of aesthetically decorative 5 GHz Wi-Fi dielectric resonator antenna (DRA) of aluminum oxynitride (AlON) transparent ceramic has been designed. High-quality-factor AlON transparent dielectric ceramics were fabricated by presintering at 1780 °C and further cold isostatic pressing (CIP) under a 200 MPa argon atmosphere. For a 9.0 mm thick specimen, the in-line light transmittance reached 83%. Optimum dielectric constant (εr = 9.32), quality factor (Q f = 47 960) and temperature coefficient (TCF = −51.7 ppm/°C) was achieved in the AlON transparent ceramic by cold isostatic pressing. As a result, the proposed aesthetically decorative DRA can achieve an impedance bandwidth of 32% (4.48–6.19 GHz), a high radiation efficiency of 85%, and a low cross-polarization discrimination (XPD) of −30 dB. To achieve a broad bandwidth, the proposed antenna was excited in its dominant TE111 x mode and higher-order TE113 x mode. The proposed antenna is thus an excellent candidate for an indoor decoration Wi-Fi antenna.

In this communication, the author presents an eight-element sequentially rotated (SR) circularly polarized (CP) dielectric resonator antenna (DRA) for operation in the IEEE 802.11a standard. A novel resonating element composed of a crescent slot (CS) used to excite a rectangular dielectric resonator (RDR) is proposed that has two orthogonal modes TE y 1δ1 and TE x δ21 as required for CP radiation. An SR series-parallel geometry is used to prototype the array feed network to allocate the array elements to symmetrical positions. The phase progression of each element was 45 along the array, and the signal magnitude was distributed evenly based on the binomial theory to enhance the antenna performance. The prototyped SR array had a size of 46 Â 46 Â 0:813 mm 3 and was measured and characterized in order to authenticate the design. The resonance bandwidth (S 11 < À10 dB) was found to be 14.28% with a 3 dB axial ratio (AR) of 17.7% for right-hand CP. The gain varied from 15.71 to 16.26 dBi within the operating band. The size, gain, and impedance bandwidth of the proposed array make it a potential candidate for devices operating in the IEEE 802.11a band.

In this article, Dual port excitation spiral shaped dielectric resonator multiple input multiple output (MIMO) antenna is explored for wideband application. Dual coaxial feeding in inner and outer edge of spiral geometry generates orthogonal hybrid modes. Merging of various hybrid modes lead to a wide bandwidth of operation. HE11δx, HE11δy and HE12δx, HE12δy0.25em orthogonal radiating modes are investigated at 8.7 GHz and 11 GHz resonant frequencies, respectively. Proposed antenna covers wide operating frequency range from 8–15.1 GHz to 7.8–14.6 GHz corresponding to excitation of Port‐1 and Port‐2, respectively, is achieved between ports. Isolation below −25 dB. Envelope correlation coefficient, diversity gain, Total active reflection coefficient, radiation pattern, channel capacity loss, gain, efficiency and various other characteristics of MIMO antenna are explored. This antenna can be used for various C and X band wireless applications.
