| description | In this article, a new multiband frequency reconfigurable substrate integrated
waveguide cavity slot antenna was designed using Computer Simulation Technology
software tool for addressing the specific design challenges posed by the
internet of things (IoT) based cognitive radio networks. Reconfiguration of
frequency bands is achieved using PIN diodes. The antenna resonated at 2.624,
2.664, 2.720, 2.752, 4.304, 4.532, 4.556, 5.236, 5.304, 5.368, 5.332, and
5.392 GHz. The resonant frequency capability and radiation performance are demonstrated
by both simulations and measurements. The simulated and measured results
were in agreement. The higher efficiency, gain and average bandwidth obtained are
90%, 8.2 dBi and 65 MHz, respectively. The compactness, integrity, reliability, and
performance at various operating frequencies make the proposed antenna a good
candidate for IoT applications. |
