“…Various modification approaches of monopole antennas have been adopted for bandwidth enhancement. Some of these include incorporation of a dielectric resonator, ring slot, inverted T in ground plane, simple bevel design, element smoothening, utilizing shorting pins, designing fractal elements, inserting wide open slots, integrating parasitic elements, using various substrate thicknesses, and truncated ground plane …”

This article demonstrates a method of enhancing the bandwidth of a planar monopole antenna with minor modifications of the ground plane suitable for medical applications. The narrowband monopole antenna is mounted on a modified ground plane, thus extending its impedance bandwidth and increasing the gain. The partial ground plane is transformed by integrating a rectangular plate on the upper edge of the ground plane, thus achieving a bandwidth ratio of 12:1 from 3 GHz to 37.26 GHz and again from 42.5 GHz onwards.

“…It is found that wide-slot antenna contributes to large bandwidth [10,12] whereas narrow-band slot antenna provides very small bandwidth [1]. Parasitic patches have been used along the feed line to further enhance the impedance bandwidth of the rotated square slot antenna in [14]. The narrow bandwidth of a cavity backed slot antenna has been improved by inserting a via-hole above the I-shaped slot [15].…”

Abstract-In this paper a CPW-fed annular slot antenna is miniaturized with enhanced impedance bandwidth using a reactive impedance surface (RIS) substrate. The RIS is realized by patterning 3 × 3 array of circular elements over an inexpensive FR-4 substrate which is backed by a circular metallic plane. Due to the compensation of electric and magnetic energy stored by antenna and RIS substrate respectively, the antenna resonance frequency is shifted by 53.6% compared with a simple annular slot antenna. By the inclusion of such reactive surface, input impedance of the antenna is reduced, and a remarkable improvement in impedance bandwidth from 11.66% to 64.26% is also noticed. Therefore, both miniaturization and bandwidth enhancement are achieved simultaneously with the present loading technique. The directivity of the RIS loaded antenna is increased further by loading a concentric metallic ring over the RIS loaded structure at a height above the RIS plane. The Ring & RIS loaded structure is fabricated for measurement purpose. A good agreement is obtained between the simulated and measured results for both RIS loaded and Ring & RIS loaded configurations. The ring loading over the RIS antenna provides improvement in directivity about 5 dB. The peak gain and bandwidth are measured at −1.03 dBi and 58.62%, respectively.

“…Over the recent decades, performance improvement of microstrip antennas play a great attention among the research community and multiple techniques have been proposed to enhance the performance parameters such as gain , bandwidth , efficiency , and directivity of microstrip antennas with a compact size. Gain of the antenna can be improved by using frequency selective surface (FSS) reflector , hybrid substrates , negative permeability meta material , etc.…”

A novel modified elliptical patch antenna is designed to provide performance diversity for c‐band wireless applications. Initially antenna A and antenna B are designed to enhance the radiation efficiency and bandwidth, respectively. With the similar patch and substrate size of both antennas by controlling the length of the slots and width of the feed antenna C is designed to yield unique performance in a single element. Antenna C achieves the performance of enhanced radiation efficiency and bandwidth with the reconfigurable mechanism. When antenna C switch to antenna A configuration, it resonates in the frequencies of 3.7, 5.1, and 6.35 GHz have the radiation efficiency of 82.55, 83.3, and 87.09%, respectively and whenever it turns to antenna B configuration it resonates at the bands of 4, 4.8, and, 6.7 GHz have the bandwidth of 260, 300, and 240 MHz, respectively. © 2016 Wiley Periodicals, Inc.
