“…Dual-band antenna in [21] with an average gain of 2.5 dB having dimensions 25 mm × 25 mm being compact in size operates only in WLAN band. Further, in some other designs, the antenna gains and reflection coefficient parameters are not impressive compared to the antenna dimensions [15][16][17][18][19][20][22][23][24][25]. In [26], a CPWfed multiband antenna having dimension 70.4 mm × 45 mm is implemented having an impedance bandwidth of 127 MHz for WiMAX band only.…”

“…Similarly, a 70 mm × 70 mm CPW-fed WLAN antenna implemented in [27] operating at 2.4 GHz with peak gain of 6.5 dB has a very low impedance bandwidth. The rounded corners concept is found in literature to enhance the overall gain, with stable radiation patterns [22][23][24][25]. Moreover, frequency dispersion is reduced and current is uniformly distributed on radiation surface corners using this procedure.…”

This paper presents a dual-band coplanar waveguide (CPW) fed printed antenna with rectangular shape design blocks having ultrawideband characteristics, proposed and implemented on an FR4 substrate. The size of the proposed antenna is just 25 mm × 35 mm. A novel rounded corners technique is used to enhance not only the impedance bandwidth but also the gain of the antenna. The proposed antenna design covers two ultrawide bands which include 1.1-2.7 GHz and 3.15-3.65 GHz, thus covering 2.4 GHz Bluetooth/Wi-Fi band and most of the bands of 3G, 4G, and a future expected 5G band, that is, 3.4-3.6 GHz. Being a very lowprofile antenna makes it very suitable for the future 5G Internet of Things (IoT) portable applications. A step-by-step design process is carried out to obtain an optimized design for good impedance matching in the two bands. The current densities and the reflection coefficients at different stages of the design process are plotted and discussed to get a good insight into the final proposed antenna design. This antenna exhibits stable radiation patterns on both planes, having low cross polarization and low back lobes with a maximum gain of 8.9 dB. The measurements are found to be in good accordance with the simulated results.
