“…The commonly used geometries like rectangular, ellipse, and circular structures with modifications have been widely analyzed for UWB applications [10][11][12]. Many circular antenna designs have been investigated in past to obtain improved radiation characteristics, a circular microstrip antenna with off-centered y-slot is investigated [13], it offers impedance bandwidth of 7.5% with circularly polarized performance. The gain is found to be around 3 dB in the entire bandwidth.…”

A design of annular ring microstrip antenna with finite ground structure is proposed in this paper. The proposed geometry offers impedance bandwidth of 2.362 GHz and has stable radiation patterns for all resonant frequencies in the operational band. It is also found that shape and dimension of the finite ground plane is a key factor in improving the bandwidth of the proposed geometry. The geometry is low profile and has simple structure, therefore can be used for lower band of ultra-wideband applications.

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.
