“…The proposed antenna reported in this paper decrease about more than 50% (38mm X 36mm) of antennas size comparing to the aformentiond recent previous research. Also, the results of this paper improve the results of [23] in terms of complicated design and biasing circuit problem which will be more complicated in implementation. The efficiency obtained from all states are significantly improve the results of [24].…”

This paper shows a frequency reconfigurable SIW F-slot suitable for some applications. Configurability is accomplished by embeddings PIN diode switches in the 'F' slot. The proposed antenna is equipped for exchanging between working band of 3.172 GHz to 3.606 GHz in four different narrow bands and it underpins the cognitive system for LTE2300, WiMAX and WLAN. For each case reflection coefficient is ascertained, it keeps up less than-10 dB all through the resonating frequency in all instances of diode switching. The electromagnetic energy is kept inside the cavity because of the frame of a metallic vias. In all instances of diodes exchanging, it's uncovered a decent effectiveness of efficiency and gain.

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.cognitive radio, frequency reconfigurable, internet of things, multiband, PIN diodes, SIW

“…Integrated reconfigurable antenna which provides multiple selectable features meets the above said requirement. In [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], some design schemes are available in which two antennas are integrated on a solitary substrate to optimize the space utilization. In these reported schemes, small antennas are incorporated in huge sized UWB radiator either by reutilization of large printed area of UWB antenna as ground plane for the second antenna [4][5][6][7][8][9] or by placing the small sized antenna in electrically neutral area of UWB antenna [10][11][12][13].…”

“…All these designs are good and solve the problem of underutilization of large printed area of UWB antenna. However in all reported designs, the numbers of reconfigurable features are confined to either frequency reconfiguration or NB-WB reconfiguration [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. However, single reconfiguration feature is not sufficient for future communication devices.…”

A two port, integrated reconfigurable versatile antenna is proposed here. The proposed antenna can reconfigure its frequency, bandwidth, polarization state and radiation pattern and hence is versatile in its characteristics. The antenna is integrated in such a way that the space of one antenna can be used to print two antenna structures to increase the antenna versatility into a small package. PIN diodes are placed in a position so that the electrical switching of the PIN diodes makes every part of the antenna multipurpose. The prototype has been fabricated to authenticate the simulated results. The simulated and measured results are in good agreement. The antenna can be used for Cognitive Radio application.
