“…An asymmetric E-shaped patch and proximity coupled patch antenna [13,14] also provide improved bandwidth, but the overall size is compromised. Other methods for broadening the impedance bandwidth include stacked patch antenna and E-shaped patch [15,16], L-shaped probe and shorting pins [17,18]. However, these antennas have certain drawbacks in terms of high volumetric size and design complexity.…”

Abstract-In this article, a novel design of butterfly-shaped compact and small size microstrip antenna is proposed. The radiating structure consists of four circular discs in coalesced form and fed with coaxial probe. The initial antenna resonates at 9.64 GHz with impedance bandwidth of 11.41%. The resonance frequency is further reduced to 8.12 GHz with bandwidth 10.10%, when a rectangular slot is incorporated in the initial patch. Finally, two parallel slots are embedded in the initial patch which improves the antenna bandwidth up to 21.50% (6.02-7.47 GHz). The gain and efficiency of this antenna are above 8.80 dBi and 90% respectively across the entire operating band. Radiation pattern is calculated at lower end (6.02 GHz), upper end (7.47 GHz) and centre frequency (6.75 GHz) of operating band. The proposed antenna is fabricated, and measured results are validated with the simulated ones.

“…The design of efficient and compact size antennas for wideband applications is still a major challenge nowadays. Many microstrip-fed and coplanar waveguide-fed antennas have been reported for UWB applications [6][7][8][9][10][11][12] and the UWB propagation channel has also been studied [13]. These antennas employed either the monopole configuration with different shapes (circular ring, ellipse, annual ring, triangle, pentagon or hexagon) [10,11] or the dipole configuration (e.g.…”

An offset-fed ISM/Ultra-wideband (UWB) antenna with a slotted ground plane designed for on-body communications is presented in this paper. The antenna consists of a radiator very close to a square shape, a feed line slightly offset from the middle along the radiator side and three rectangular slots at the top edge of the ground plane. The offset feed line is used to improve the radiation pattern for on-body communications and the slots on the ground plane are used to improve impedance matching of the antenna. The antenna is studied using computer simulation. For verification of simulation results, the antenna is fabricated and measured. Simulated and measured results show good agreements in terms of reflection coefficient, gain, efficiency and radiation pattern. Measured results show that the antenna can achieve a wide bandwidth from 2.38 to 14.5 GHz with more omnidirectional radiation patterns in the E-plane than conventional monopole, making it a potential candidate for on-body communications using UWB.

“…Several methods have been introduced to enhance the impedance bandwidth of microstrip antennas such as utilizing a thick substrate [8] and modification in the patch geometric structure like E-shaped patches [9][10][11][12], U-shaped-slot patches [13,14] and V-shaped patch [15]. Other common methods to improve the impedance bandwidth are the implementation of stacked patch antennas [16,17], L-probe feed [18,19], shorted-patch [20,21] and using shorting pins [22].…”

Abstract-Novel designs of probe-fed broadband shorted patch antennas for ultra-wideband (UWB) applications are presented in this paper. In these designs, unequal resonance arms fed by a folded patch produce multi resonances to broaden the impedance bandwidth. In the first design, the antenna consists of an asymmetric E-shaped patch, a folded-patch feed and shorting pins. This antenna is achieved by four adjacent resonances with the measured −10 dB impedance bandwidth of 76.18%. The pins are utilized to miniaturize the size of the patch. By introducing a folded ramp-shaped feed in the similar structure with the first design, a wider bandwidth with the five resonances is obtained. This improved design introduces an antenna with an impedance bandwidth of more than 110% and a considerable size reduction compared to the first antenna. The antennas present resonance tuning ability within the impedance bandwidth by varying the length of unequal arms. In addition, parametric studies are performed by investigating the effects of different key parameters on obtaining optimal designs of the proposed antennas.
