A new type of hybrid resonant circuit model is investigated theoretically and experimentally. The resonant model consists of a right hand (RH) patch part and a composite right and left handed (CRLH) part (RH + CRLH), which determines a compact size and also a convenient frequency modulation characteristic for the proposed antennas. For experimental demonstration, two antennas are fabricated. The former dual-band antenna operating at f-1=3.5 GHz (Wimax) and f+1=5.25 GHz (WLAN) occupies an area of 0.21λ0×0.08λ0, and two dipolar radiation patterns are obtained with comparable gains of about 6.1 and 6.2 dB, respectively. The latter antenna advances in many aspects such as an ultrasmall size of only 0.16λ0×0.08λ0, versatile radiation patterns with a monopolar pattern at f0=2.4 GHz (Bluetooth), and a dipole one at f+1=3.5 GHz (Wimax) and also comparable antenna gains. Circuit parameters are extracted and researched. Excellent performances of the antennas based on hybrid resonators predict promising applications in multifunction wireless communication systems.

Abstract In this article the design and implementation of dual band circularly polarized antenna which is backed with AMC is presented. The proposed antenna consists of a novel heart shaped concentric ringshaped patch attached to meander line. The dimension of the antenna without AMC is 0.24 λ0 × 0.140 λ0 × 0.012 λ0 × and with AMC 0.43 λ0 × 0.43 λ0 × 0.32 λ0 and designed on a commercial FR4 substrate. The antenna gets worked at dual band applications such as 2.4 GHz (wi-fi) operates from 2.3 GHz to 2.5 GHz and 5.2 GHz (WLAN) operates from 4.7 GHz to 5.9 GHz and also gets circular polarization from 2.3 GHz to 2.5 GHz (200 MHz) and 4.95 GHz to 5.40 GHz (450 MHz) is achieved. In this article the proposed model is investigated towards circular polarization, radiation patterns and current distributions by varying parametric analysis is carried to analyze overall performance of antenna with and without AMC.

This paper presents a novel antenna configuration to support reconfigurable multi-beam feature with dual-band capability. The proposed design uses four double Vee dipoles with their arms printed on either sides of a substrate and fed through a single coaxial input probe. A single directional beam that can be configured in four directions at quadrature angle in the azimuth (xy-plane) and corresponding dual, triple and quad beams have been obtained by controlling the state of four PIN diodes. A prototype of the proposed antenna has been designed and fabricated. Measured antenna parameters are in good agreement with that of simulated parameters. This highly planar antenna shows similar radiation patterns at both design frequencies enabling concurrent dual-band communication for all fifteen possible beam configurations.

A compact dual-band antenna for ISM (2.45GHz) or WiMAX (3.15GHz) applications by low-temperature co-fired ceramic (LTCC) technology is presented in this paper. The proposed antenna is composed of multi-layer structures to reduce the sizes effectively. The simulated results show that the dimensions of the antenna are 11×4.2×1.2mm3, with the 2:1 VSWR impedance bandwidth definition, the lower and upper band have the bandwidth of 80 and 90 MHz. The novel antenna has realized miniaturization and omni-directional radiation patterns across the whole operating frequency band.

Abstract Designing miniaturized multiband antennas to cover both the 5G new radio frequencies (FR1 and FR2) simultaneously is a challenge for wireless communication researchers. This paper presents two antenna designs : a dual-band printed antenna of size 18 × 16 × 0.285 mm3 operating at FR1–5.8 GHz and FR2–28 GHz and a triple-band printed antenna with dimensions 30 × 25 × 0.543 mm3 operating at FR1–3.5 GHz and 5.8 GHz (sub-6 GHz microwave frequency bands) and FR2–28 GHz (mm-wave frequency band). The final projected triple-band antenna has a compact size with an impedance bandwidth of 12.71%, 11.32%, and 18.3% at 3.5 GHz, 5.8 GHz, and 28 GHz, respectively with the corresponding gain of 1.86 dB, 2.55 dB, and 4.41 dB. The measured radiation characteristics of the fabricated prototypes show that the proposed designs are suitable for trendy 5G-RFID and mobile Internet of things (IoT) applications.
