“…Here patch is fabricated on glass epoxy substrate which is suspended above the ground plane using an air gap of 0.16 cm. The effective dielectric constant (re) of suspended configuration is calculated by using (14) and patch radius for TM11 mode frequency of around 850 MHz is calculated using (15).…”

“…Along with regular shapes, modified patch shapes like Spanner shape antenna, modified rectangular ring shape antenna loaded with semi-circular patch have been used for achieving wideband or dual band characteristics [15], [16]. However, in [15], [16] detailed study to explain effects of modifications in patch shapes on frequency and impedance, for achieving reported antenna characteristics is not given. Using a Crescent shape patch, ultra-wide band and dual band response is obtained [17]- [19].…”

Novel design of multi-band Crescent shape microstrip antenna is proposed. Modifications in equivalent circular patch yields new resonant modes nearer to the TM11 and TM21 modes in circular patch that gives four band frequency response showing dual polarizations. Proposed design gives 1 to 1.5% of bandwidth at each frequency with broadside radiation pattern. The resonance frequency equation by defining the resonant length at each mode in the Crescent shape patch, is proposed. The frequency calculated using the same agrees closely with simulated result. The air suspended design of crescent shape patch is presented which yields co-polar peak gain of above 1.5 dBi.

“…A rectangular monopole antenna with a truncated ground plane was designed with a feeding mechanism, and the researcher achieved a 118.3% (3.8 -14.8 GHz) bandwidth [12]. Other research also proposed a spanner shape monopole antenna with a rectangular slit [13]. This design has a UWB bandwidth of 112.5% (2.98-10.64 GHz).…”

This paper described the design of a compact printed monopole antenna with U-shaped Defected Ground Structure (DGS) for ultrawideband (UWB) application. The implementation of DGS facilitates in reduction of size and increases in antenna performance. The DGS and antenna design parameters are simulated using CST Microwave Studio 2020, and the measurement is carried out using R&S Vector Network Analyzer (VNA). The optimized design of the proposed UWB antenna with U-shaped DGS presented smaller in size (23.88mm x 29.10mm x 0.813mm) with a reduction of 32% compared to the conventional design, which fabricated on Rogers RO4003C substrate with a relative permittivity, εr = 3.38. Simulation results show that the proposed antenna provided a very wide range of frequency (3.2 - 20GHz), 144.8% of BW. The simulated and measurement results show good agreement.

“…For multiple operating frequencies, multiple antennas installation is difficult due to the limited space within the compact wireless terminal. To solve these problems, researchers designed many novel antennas in the last few years just like reconfigurable antennas [2,3], UWB antennas [4], and multiband antennas. UWB antennas are very useful for the bio-medical purpose such as lung cancer detection and microwave imaging [5,6].…”

The paper presents a highly efficient, low cost, ultra-wideband, microstrip monopole antenna for microwave imaging and wireless communications applications. A new structure (z-shape, ultra-wideband (UWB) monopole) is designed, which consists of stepped meander lines to achieve super-wide bandwidth and high efficiency. Three steps are used to design the proposed structure for the purpose to achieve high efficiency and wide bandwidth. The antenna bandwidth is enhanced by varying the length of meander line slots, optimization of the feeding line and with the miniaturization of the ground width. The simulated and measured frequency bands are 2.7–22.5 GHz and 2.8–22.7 GHz (156% fractional bandwidth), respectively. The dimensions of the antenna are 38 mm × 35 mm × 1.57 mm, and its corresponding electrical size is 2.41 λg × 2.22 λg × 0.09 λg, where guided wavelength λg is at the center frequency (12.75 GHz). This antenna achieved a high bandwidth ratio (8.33:1). The realized gain is varying from 1.6–6.4 dBi, while that of efficiency is 70% to 93% for the whole band. Radiation patterns are measured at four operating frequencies. It has an acceptable group delay, fidelity factor, and phase variation results that satisfy the limit of ultra-wideband in the form of the time domain.
