This manuscript proposes a triple band filtering antenna operating in the frequency range of 2.4 to 2.484 GHz, 4.2 to 4.5 GHz, and 5.15 to 5.825 GHz for possible application in WLAN and aeronautical radio navigation. Initially, a conventional square shaped monopole antenna is designed at 4 GHz, in which staircases are introduced at the edges to enhance bandwidth. Later, a triangle shape is carved out of square patch and cascaded at the junction to generate the proposed sunflower shaped fractal filtenna. Also, the ground plane is modified to further enlarge the bandwidth. By inserting C shaped complimentary split ring resonator slot on the feed line, a stop band is created at 3.5 GHz. Within the proposed frequency band of operation, the filtenna depicts omni‐directional radiation pattern, good selectivity, and low insertion loss. Also, the VSWR observed is less than 2 and peak antenna gain is 3.5 dBi. A good uniformity is achieved between the simulation and the experimental.

This article presents an integrated technique for reconfigurable substrate integrated waveguide (SIW) and reconfigurable patch antenna by using the varactor diodes. A reconfigurable SIW filter and reconfigurable patch antenna were integrated using the multilayer technique into a single structure in order to realize the integration technique. Design and validation of an equivalent circuit with the varactor diode is presented to study the tunable mechanism. A good performance between the simulated and measured results was achieved. This proposed structure of the reconfigurable integrated SIW filter and antenna is useful for wireless communication systems especially in telecommunication technology.

Abstract-In this paper, a new compact coplanar waveguide (CPW) ultrawideband (UWB) antenna with an electronically tunable notched band is proposed for an overlay onto cognitive radio (CR) systems. The proposed antenna utilized a rectangular microstrip resonator in the bottom layer to create a single notched band and to realize tunability and miniaturization using varactors. The center frequency of the notched band can be electronically tuned by changing the effective electrical length of the microstrip resonator, which is achieved by employing two varactor diodes at the resonator edges. Moreover, the simple biasing of the varactor diodes has a small effect on the antenna performance. Experimental results show that the proposed antenna can selectively have a band notch over a continuous operating band about 1.44 GHz from 4.77 to 6.21 GHz to prevent the interference to the primary users that are operating in this band such as the WLAN (5.15-5.35 GHz; 5.725-5.825 GHz) and the WiMAX (5.25-5.825 GHz). Good agreement is found between the simulated and the measured data.
