Summary This paper presents the design of a dual‐band circular patch antenna for the application requirements of wireless handheld devices and various wireless sensor modules operating in WiMax and 5G NR Bands. The design originated from a single‐band conventional circular patch antenna and ended up with a dual‐band circular patch. A novel hexagon‐shaped slot was preferred to achieve dual‐band performance in the circular patch antenna. The simulation level performance of the antenna is verified using the Advanced Design System 2019 tool. An FR4 material with a height of 1.6 mm is selected as a substrate for the patch antennas. The return loss and radiation pattern behaviour of the patch antennas are measured using a network analyser and an anechoic chamber. The fabricated prototype achieves dual‐band performance at 3.47 and 6.96 GHz. Simulated and measured results show that the proposed hexagonal‐shaped slot in the circular patch provides a dual‐band behaviour.

“…The antenna 18 provided 58.72% bandwidth along with good copolarization to cross‐polarization isolation level. In the literature 19, four hexagonal shaped DGS was introduced which was further integrated with microstrip antenna, which helped to improve the gain and impedance bandwidth (58%) by lowering the cross polarization level. A multiband microstrip antenna was explored in Reference 20 for ISM/WiMAX/WLAN/4G/Sub 6 GHz 5G mobile communication.…”

The article presents a new reconfigurable antenna suitable for cognitive radio (CR) application under interweave paradigm. The new sleeve-like geometry is improvised in the antenna for designing broadband sensing antenna and it consists of a hexagon shaped metallic patch along with modified coplanar ground plane structure and feed line (nonconventional coplanar waveguide feed). The p-in diodes are also incorporated with the printed antenna. By varying the switching states of the diodes, frequency hopping occurs over the frequency range 3.75 to 12.67 GHz (108.64% BW) which is better compared to the existing sensing antennas used for designing CR antenna. The antenna also offers suitable gain and omnidirectional radiation pattern over the operating range of frequencies. In addition to frequency domain analysis, time-domain synthesis of the proposed antenna is also executed by using well-known electromagnetic solver CST software. Moreover, the antenna is fabricated and measured parameters are in good accordance with measured results.
