“…The proposed DRA is also measured in far field anechoic chamber. Figure 10 shows the measured and simulated radiation patterns in the H (xz)-plane and E (yz)-plane at five different frequencies (4,8,11,16 and 22 GHz). In the H-plane, it can be seen that the radiation patterns are almost symmetrical and stably omnidirectional across the operating frequency range.…”

A new simple compact ultra-wideband (UWB) dielectric resonator antenna is presented. The antenna consists of a modified stepped microstrip-fed monopole printed antenna loaded with a rectangular dielectric resonator, truncated ground plane, and a parasitic strip underneath the dielectric resonator (DR). Using an optimized truncated ground plane and a combination of stepped feed line with DR an ultra-wide impedance bandwidth of 153% for (∣S11∣ ≤ −10 dB), covering the frequency range of (3.7–28 GHz) is achieved. The added parasitic strip can improve the radiation pattern, especially at high frequencies. The proposed antenna covers almost the entire UWB (3.1–10.6 GHz), Ku (12.4–18 GHz), and K (18–26.6 GHz) frequency bands. Also this antenna has an omnidirectional and stable radiation pattern over the whole operating frequency range and a compact size of (15 × 20 × 5.8 mm3) that make it suitable for wideband wireless system applications. This structure is light weight and can be easily fabricated. A prototype is built and measured. The simulated and measured results are in good agreement.

“…High evaluation cost may not be a problem for design verification, but it becomes a fundamental issue for EM‐driven design that normally requires a large number of antenna simulations. Both academic and industry standard is to conduct the design through parameter sweeps, which is a laborious process, often guided by engineering experience . Such hands‐on methods can hardly lead to optimum designs yet allow for finding acceptable results within reasonable timeframes.…”

Fast redesign and geometry scaling of multiband antennas using inverse surrogate modeling techniques

Redesign of antenna structures for various operating conditions or substrate parameters is a practically important problem in antenna engineering. At the same time, it is challenging because finding an optimum set of geometry parameters for a specified operating/material conditions requires going through an entire design optimization process. The problem is even more challenging for multiband antennas where 2 or more bands need to be independently controlled and the joint influence of some of antenna dimensions on several bands has to be taken into account. In this work, we propose a simple technique for rapid dimension scaling of multiband antennas, which uses inverse surrogate modeling techniques. The inverse surrogate model constructed using a set of reference designs optimized for several values of operating frequencies allows us to predict optimum dimensions of the antenna structure of interest corresponding to a required set of operating frequencies. The model is constructed at the level of coarse‐discretization electromagnetic simulations; therefore, it undergoes enhancement so as to be reliably used to redesign the antenna at the level of its high‐fidelity electromagnetic model. A correction procedure is further applied to accommodate the initial scaling errors. Our approach is demonstrated using a triple‐band uniplanar dipole antenna.

“…Considerable research efforts towards the design of miniaturized UWB antennas 2,3,4 have been made. A compact UWB antenna which consists of a microstrip fed monopole, printed on a 13mm x 22.5mm substrate, with a truncated ground plane loaded with a dielectric resonator was discussed in a previous paper 5 . By making use of the advantages of coplanar fed antennas, a small coplanar UWB antenna was presented in a paper 6 with a fairly compact dimension of 19mm x 16mm.…”

A novel compact coplanar stripline (CPS) fed antenna for ultra-wideband (UWB) application is investigated. The proposed antenna consists of a stair-case shaped radiator along with a shorted strip. The prototype is designed on a substrate of dielectric constant 4.4, with an overall dimension of 25mm x7mm x1.6mm. The antenna offers a 2:1 VSWR bandwidth from 3.1-11.4 GHz, with an average gain of 3dBi and average radiation efficiency of 75% throughout the band. Measured group delay and transmission characteristics show that the proposed antenna is a good candidate for UWB communication systems.
