“…The most current interest in the reconfigurable integration delivers a wide form of exploration. [8][9][10][11][12] However, imperfectly impedance matching will cost the poor insertion loss level especially in filter design. 8 Because of these reasons, the demand for a better planar topology is increasing which not only requires smaller size but also offers a better overall performance for insertion loss.…”

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.

In recent year, various filtenna circuits have been developed satisfying the objectives and prerequisites of wireless communication. Some of these developed designs are new or some are the improved version of previous works whereas the others are the combination of conventional methods. This article presents the review of filtenna circuits starting from the beginning to the improvements until date. This article starts with brief overview of various filters with their design strategies and ends in its implementation in filtenna designs followed by discussion on several filtenna designs in term of size and overall performances. Among various designs, bandpass, and bandstop filters are extensively used in filtenna realization as it provides a better selectivity in desired band. Various planar filtenna circuits, based on either defected ground structure (DGS) or resonator or SIW filters are reviewed and presented. Besides, planar filtennas, these filters are also integrated to the aperture of horn antennas for the realization of horn filtennas, applicable for high frequency operations. It is observed that SIW based filtennas exhibited narrow impedance bandwidth. This feature can be improved by doubling substrate layer as well as the number of metallic ways. Whereas, resonator based filtennas use resonator based filters along with DGSs to enhance impedance bandwidth as well as minimize mutual coupling and cross‐polar radiation. Apart from single element filtenna, filtenna arrays, and reconfigurable filtennas (including planar and horn reconfigurable filtennas) are presented. This review article may be helpful for beginners working on filtenna circuits and also such a review process is not available in the open literature to the best of author's knowledge.
