A New Circular Slot Based Dual Frequency Band Reconfigurable Antenna for 5G and Wi-Fi Applications | IEEE Conference Publication | IEEE Xplore
This work purports a unique reconfigurable antenna with a compact and simple structure and functions at two different frequencies viz 5GHz (Wi-Fi applications) and 28GHz (mmWave 5G) making it very suitable for present day mobile applications. The antenna structure comprises of two patches viz a main radiating circular patch and one subsidiary rectangular patch which is connected to the main radiating patch through a PIN diode. In the OFF mode of the PIN diode, the antenna operates at 5GHz and in the ON mode of the PIN diode, the antenna radiates at 28GHz. The antenna is imprinted on FR4 material with the relative permittivity of 4.4 and the total footprint of 30×30×1.6 mm3. The antenna exhibits an excellent gain for both the desired frequencies.
Dual band triangular slotted stacked microstrip antenna for wireless applications | Central European Journal of Engineering
In this paper stacked configuration of microstrip antenna is used to produce dual wide band which is suitable for various wireless applications. Using triangular slot and stacking of foam substrate of dielectric constant 1, two bands of bandwidth 18.70% and 12.10% is obtained. The antenna is fed by coaxial probe feeding technique. The proposed patch antenna is designed on the foam substrate and simulated on the Zeland IE3D software.

Circular Slot loaded ultrawideband circularly polarized Antenna | IEEE Conference Publication | IEEE Xplore
In this paper, a circular slot loaded circular monopole antenna for ultrawideband circularly polarized applications is presented. The antenna consists of a circular radiator fed by a modified feedline and multiple slots loaded modified coplanar waveguide (CPW) ground plane. The ground plane is also loaded with quarter elliptical slot and semicircular stub to achieve circular polarization. The overall dimensions of the proposed antenna are 17×20 mm2. The antenna has an impedance bandwidth of 4.41-14.0 GHz (104.2%) and axial ratio bandwidth (ARBW) of 5.87-13.66 GHz (79.77%). It has a peak gain of 5.34 dBi. The proposed antenna provides right hand circularly polarized (RHCP) radiation patterns along +z axis. It has advantages of compact dimensions, wide impedance bandwidth and wide axial ratio bandwidth over previously reported structures.
Design of wideband dielectric resonator antenna with square slots excited using microstrip line at 26 g hz | PDF
The document describes the design of a wideband dielectric resonator antenna (DRA) with square slots for 5G communication applications operating at 26 GHz. Square slots of two different sizes are introduced in the DRA to reduce its quality factor and achieve a bandwidth of 3 GHz (11.5%) from 25-28 GHz. The DRA is excited using a microstrip feed line. Simulation results show the proposed antenna achieves a peak gain of 4.8 dBi and radiation efficiency of 93%. Compared to reference DRAs, the proposed antenna with slots provides the widest bandwidth for 5G millimeter-wave applications. - Download as a PDF or view online for free
