Reconfigurable Antenna for sub-6 GHz and C band Applications

Abstract

 The future of 5G New Radio (NR) development has many significant concerns. To overcome the working frequency band issue, a frequency-reconfigurable patch antenna based on pin diodes is presented and investigated. The antenna's compact dimensions (30 mm x 20 mm x 1.6 mm) are due to its construction on FR-4 substrate material with a relative permittivity of  = 4.4. A feed port and two switches allow frequency reconfiguration in the antenna module. C-band service is provided by this antenna module's ability to switch between operating at 3.4 GHz, 4.8 GHz, and 7.5 GHz. Simulation of the proposed antenna is accomplished in the CST microwave studio. The presentation and discussion of the radiation pattern and S parameter demonstrate the feasibility of the proposed antenna.  Antenna module's size and performance are both precisely appropriate.
