“…With the introduction of ceramic material that comes with several attractive features in 1980s, Dielectric Resonator Antenna (DRA) has become an interesting candidate for 5G applications [13]. Other advantages of the DRA include its small size, light weight, flexible excitation, and relatively wide bandwidth compared with a microstrip antenna [14][15][16][17]. Studies in [18] show that the comparison between dielectric resonator antenna, and microstrip antenna performance at 35 GHz provides impedance bandwidth for microstrip antenna with only 2.6%; however, DRA achieves 6 times higher impedance bandwidth which is 15.6%.…”

Abstract-In this paper, a Rectangular Dielectric Resonator Antenna (RDRA) with a modified feeding line is designed and investigated at 28 GHz. The modified feed line is designed to excite the DR with relative permittivity of 10 which contributes to a wide bandwidth operation. The proposed single RDRA has been fabricated and mounted on a RT/Duroid 5880 (ε r = 2.2 and tanδ = 0.0009) substrate. The optimized single element has been applied to array structure to improve the gain and achieve the required gain performance. The radiation pattern, impedance bandwidth and gain are simulated and measured accordingly. The number of elements and element spacing are studied for an optimum performance. The proposed antenna obtains a reflection coefficient response from 27.0 GHz to 29.1 GHz which cover the desired frequency band. This makes the proposed antenna achieve 2.1 GHz impedance bandwidth and gain of 12.1 dB. Thus, it has potential for millimeter wave and 5G applications.

“…As it is well known, signal wavelength becomes shorter as the frequency increases, so smaller antennas (which are inversely proportional to carrier frequency) can be used at millimeter frequencies to give the required gain overcoming attenuation effects [3]. There are many challenges for the millimeterwave circuits such as the necessity of low-cost, and high powerefficiency, and of accurate models using computer aided design.…”

“…There has been a growing demand for indoor short-range communication systems such as millimeter-wave wireless personal area networks (WPANs) to provide high-speed multimedia data services in recent years [1][2][3]. It is commonly known that delay dispersion due to multipath propagation results in significant channel degradation.…”

Abstract-A geometrically based channel model is proposed to describe radio propagation in an indoor environment with directional antennas.In conventional geometric channel models (GCMs), distribution of scatterers does not take into account the antenna properties. A different approach is taken here for directional channel modeling. The locations of scattering objects are defined using nonCartesian coordinates comprising an auxiliary geometric parameter ρ and angle-of-arrival (AOA) φ. Subsequently, we present a systematic method to study the influence of antenna pattern on scatterer distribution by applying two heuristic rules, which underpin the connection between the physical wave-propagation process and its canonical GCM. Provided with model preliminaries, important channel parameters including power azimuthal spectrum (PAS), power delay spectrum (PDS), mean effective gain (MEG), and antenna-decoupled PAS are derived and compared against the published data in the existing literature to demonstrate the usefulness of the proposed model.
