“…Hybrid reconfiguration combines either frequency, radiation pattern, or polarization in the same reconfiguration. Among the frequent combination is frequency/radiation pattern since it is required for various applications and the requirement to guide the beam at the same time [110], [111]. Study in [112], designed an arc-shaped circular patch frequency-radiation pattern reconfigurable antenna for multiband wireless communication applications.…”

Wireless Body Area Network (WBAN) technology is gaining popularity in personal communication due to the expanding improvement in wireless technology. Wearable antennas are utilized in various WBAN applications including personal healthcare, entertainment, military, and many more due to their attractive characteristics and the potential for integrating lightweight, compact, low-cost, and adaptable wireless communications. A wearable reconfigurable antenna will allow a single antenna to operate at multiple resonant frequencies, radiation, polarization or hybrid between them, by using single or multiple active switching devices for signal transmission and reception in different parts of human body, rather than using multiple antennas. Over the years, several review papers were reported on wearable antennas which discussed the requirements and issues of wearable antennas in terms of their design, fabrication, and measurement. Nowadays, WBAN technology employs a single wearable reconfigurable antenna to perform multiple functions in different parts of human body. Recently, a significant amount of work has been carried out in the area of wearable reconfigurable antennas for WBAN applications. This paper presents a comprehensive review of the requirements and analysis needed for wearable reconfigurable antennas such as Specific Absorption Rate (SAR) for on-body analysis, investigation of the antennas in bending conditions, reconfigurable techniques and reconfigurable performance metrics.

“…In existing literature [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31], dual-polarization antennas have been designed by employing orthogonal feeding structures to excite the antenna [13], [14]. Achieving adequate isolation between the two ports of the dual-polarization antenna is crucial for optimal performance.…”

“…Various reconfigurable structures have been developed specifically for polarization-diversity purposes [21]. In [22], a quadric-polarization-diversity patch antenna was achieved by manipulating the radiation pattern through a control circuit. The suggested design offered right-handed and left-handed circularly polarized (CP) as well as orthogonal linearly polarized (LP) patterns.…”

This paper presents a triple-port dual-polarized antenna designed for X-band applications with a wide beamwidth. The antenna utilizes 50 Ω probe feeding structure, resulting in a small size of 20 × 20 mm 2 . The proposed antenna is developed for X-band applications, operating at 10.7 GHz with a bandwidth of 200 MHz. The structure comprises two stacked substrates with electrical properties (2.2, and 4.5 permittivities, 1.5 mm height). The top layer features a rectangular patch with two ports for exciting orthogonal polarizations, while the middle layer includes a circular patch serving as a ground plane for the rectangular patch. The excitation of TM01 mode in the circular patch generates a conical radiation pattern, and the antenna exhibits an overlapping bandwidth from 10.3 GHz to 10.9 GHz. The peak gains, illustrated over the frequency range, reach 5.2 dBi for the circular patch and 7 dBi for the rectangular patch. Fabrication and measurements of the antenna demonstrate good agreement between experimental and simulation results.

“…Reconfigurable antennas are therefore highly preferred as they can easily adapt themselves to the changing environment by adjusting its operating band based on the availability of the spectrum. These types of antennas can be used for reducing the size of multi-mode and multi-band wireless systems by replacing the single frequency antennas [19,20]. Reconfigurability in filtering antenna was introduced in [21], in which a wideband-to-narrowband tunable filtenna was proposed for CR applications.…”

In this study, a compact configuration of frequency reconfigurable filtenna, designed by integrating a bandpass filter and with a monopole radiator, is demonstrated for achieving high‐frequency selectivity along with compact size. The proposed filtenna can be efficiently tuned between ultra‐wideband (UWB) and C‐band states of operation. A bandpass filter, based on rectangular stepped impedance stub loaded multiple‐mode resonator (MMR), is embedded to an elliptical monopole radiator to construct the filtenna circuit. The filtenna design approach leaves out the necessity of cascading an additional 50 Ω microstrip feed line in between the antenna and filter elements which makes the system more compact. The designed filtenna occupies 3.6–10.6 GHz band in its UWB state of operation and 3.63–4.70 GHz band in its C‐band state of operation, respectively. The UWB operating state is intended for spectrum sensing application whereas the C‐band operating state can be implemented for communication in a cognitive radio environment. The shifting between two operating states is controlled by appropriately switching the PIN diodes. An average peak gain of 2 dBi is observed within the passband. The overall size of the filtenna is optimised to 1.35λ0 × 0.96λ0 × 0.04λ0 (λ0 is calculated at 6.85 GHz). For validation purpose, the filtenna prototype is fabricated and characterised. A very close agreement is achieved with the suggested configuration.
