In this paper, a wideband printed polygon-shaped monopole antenna has been designed using microstrip line feeding technique which provides dual-notch band characteristics (2.98–3.19[Formula: see text]GHz) and (3.62–5.00[Formula: see text]GHz) by the use of slots geometry in both the patch and the ground plane. The results of the antenna have been compared both with and without slots in both planes. The initial antenna without DGS and slots in the patch was made to work in the frequency range from 2.56–5.98[Formula: see text]GHz having impedance bandwidth of about 80.09%. The proposed antenna can be made usable for multi-band applications such as WLAN (2.4/3.2/5.2/5.8[Formula: see text]GHz) and Wi-MAX (3.5 and 5.5[Formula: see text]GHz) applications providing fractional bandwidth (FBW) of 85.36% (2.33–5.80[Formula: see text]GHz) and maximum peak gain of 5.65[Formula: see text]dBi at 3.50[Formula: see text]GHz. The value of return loss obtained is about 53.36[Formula: see text]dB at 2.56[Formula: see text]GHz. Prototype of the final antenna is fabricated and the results are verified with the simulated ones.

This paper presents a simple broadband planar monopole microstrip patch antenna with curved slot and partial ground plane. The proposed antenna is designed and fabricated on commercially available FR4 material with εr = 4.3 and 0.025 loss tangent. Bandwidth enhancement has been achieved by introducing a curved slot in the patch and optimizing the gap between the patch and the partial ground plane and the gap between the curved slot and the edge of the patch. Simulated peak gain of the proposed antenna is 4.8 dB. The impedance bandwidth (defined by 10 dB return loss) of the proposed antenna is 109% (2–6.8 GHz), which shows bandwidth enhancement of 26% as compared with simple monopole antenna. The antenna is useful for 2.4/5.2/5.8-GHz WLAN bands, 2.5/3.5/5.5-GHz WiMAX bands, and other wireless communication services. Measured results show good agreement with the simulated results. The proposed antenna details are described and measured/simulated results are elaborated.

This paper presents the design of a compact size band patch antenna for 5G wireless communications. This wideband antenna was designed on a glass substrate (12 × 11 × 2 mm3) and is optically transparent and compact. It consists of a radiation patch and a ground plane using AgHT-8 material. The antenna design comprises rectangular shaped branches optimized to attain the wideband characteristics. The calculated impedance bandwidth is 7.7% covering the frequency range of 25 to 27 GHz. A prototype of the antenna and various parameters such as return loss plot, gain plot, radiation pattern plot, and voltage standing wave ratio (VSWR) are presented and discussed. The simulated results of this antenna show that it is well suited for future 5G applications because of its transparency, flexibility, light weight, and wide achievable frequency bandwidth near the millimeter wave frequency band.

A novel planar Yagi antenna printed on a microwave substrate with dielectric constant of 3.55 for Ku band applications has been presented in this paper. The proposed antenna has been fed by the slow-wave half-mode substrate-integrated waveguide and has achieved good characteristics, such as reduced size, high gain, broadband, and low insertion loss. The proposed antenna has been fabricated by Rogers 4350 substrate with lengths of two arms for dipole 0.46 λ0. Measured results indicate that the impedance bandwidth (below −10 dB return loss) is from 15.4 GHz to 19.4 GHz with peak gain 7.49 dBi. Both simulations and experiments convince that the proposed antenna could have reliable applications for Ku band wireless communications.

In this paper, an Ultra Wideband (UWB) antenna is presented. The antenna radiating patch is circular in shape with coplanar waveguide (CPW) feeding technique. The proposed chamfering to the outer edges of the ground plane successfully widens the -10 dB impedance bandwidth of the antenna to cover from 1.92 GHz up to 15.16 GHz (correspond to 155% fractional bandwidth). The antenna gain varies from 2 to 5 dB over the operating band. Parametrical studies have been conducted for four different conditions of the ground plane; without chamfering, chamfering on the inner edges, chamfering on the outer edges and both chamfering of inner and outer edges. The effects of distinguished chamfering conditions to antenna performance are analyzed.  The measured and simulated results for reflection coefficients and radiation patterns (2.45 GHz, 3.5 GHz and 5.8 GHz) are presented. The corresponding realized gains are 2.14 dB, 2.85 dB and 3.4 dB respectively. The measured results satisfactorily agreed with the simulated ones. The antenna is 8 - 37 % wider bandwidth than previous research.

Abstract A microstrip line –fed broadband dual circular polarized, two port printed monopole antenna is presented. The antenna consists of a ground plane with arrow shaped stub at the corner and a pair of inverted L-shaped feed lines. The 3dB axial ratio bandwidth of the antenna is about 58%(1.7GHz-3.1GHz) in which the return loss and isolation are better than 10dB and 12dB respectively. A parametric study of proposed antenna’s geometric parameters is given for understanding of the antenna performance. The realize gain, reflection coefficient (S 11 ) and transmission coefficient (S 21 ) are higher than 1, 10 and 12dB respectively within the entire axial ratio bandwidth (ARBW).

This paper presents the design of a microstrip line fed irregular hexagonal shaped monopole antenna. The antenna consists of a sliced semi-circular ground plane with a square slit below the feed line which exhibits an Ultra Wide Band (UWB) of 7.5GHz. A frequency notch band (5.1GHz – 5.57GHz) is obtained by introducing ‘U’ shaped slot on to the proposed antenna. The proposed monopole is fabricated, measured for reflection coefficient, radiation pattern and peak gain to validate the performance of the antenna.
