TL;DR: In this paper, a new mushroom-shaped 2.4GHz dielectric resonator antenna has been proposed, which can achieve a higher impedance bandwidth of about 71% which is generally 10% in the case of conventional DRA.
Abstract: The use of dielectric resonator antenna (DRA) has gained massive interest in the field of microwave and millimeter-wave applications due to the absence of metal parts, which lead to loss and power dissipation at higher frequencies. This paper has proposed a new mushroom-shaped, 2.4GHz dielectric resonator antenna having higher impedance bandwidth. This new antenna is designed using a material of dielectric constant near to 10 and can achieve a higher impedance bandwidth of about 71% which is, generally 10% in the case of conventional DRA. The hybrid antenna gain (5dB), higher radiation efficiency, wideband width, and voltage standing wave ratio can make it compatible with customized different applications of communications. The proposed antenna is lighter in weight and also cost-effective. Finite element methods have applied to design the antenna as well as verify the results.

TL;DR: In this article , a small cylindrical DRA antenna with a partial ground plane fed by a key-shaped microstrip line is presented, which has a band that goes from 2.03 to 3.06 GHz and a fractional bandwidth of 40%.
Abstract: This work presents a small cylindrical DRA antenna with a partial ground plane fed by a key-shaped microstrip line. It is made up of a 9.8 relative permittivity resonator and a dielectric constant of 4.4 FR4 substrate. To improve the antenna’s performance, partial ground plane and feeding mechanism techniques were used. HEM11δ basic mode is transmitted through DRA via the key-shaped microstrip line connected to the antenna. DRA excited the fundamental frequency by aligning the DRA’s position, which results in more coupling. The proposed antenna has a band that goes from 2.03 to 3.06 GHz and a fractional bandwidth of 40%. The concept proposed here is ideal for Wi-Fi applications.
