“…Because of the electrical coupling between antenna elements by edges of the adjacent arms, the phase shift of M 1 can be described as the combination of phase shift on a pair of adjacent arms and phase shift generated by the electrical coupling between the two arms. Moreover, in the path M 1 , the CSs-based slow-wave structure [28][29][30][31] can help get greater phase shifts in a limited distance. The antenna is designed on a double-layer printed circuit board, and the antenna elements are fed by a double-sided parallel strip line (DSPSL) [32].…”

A method of designing two‐element compact multiple‐input and multiple‐output (MIMO) antennas with good isolation based on slow‐wave corrugated strips (CSs) is presented in this paper. Using the slow‐wave characteristic, a pair of CSs is applied as arms of each dipole antenna element to realise the compact design. A metal plane is placed between the two dielectric boards serving as the reflector so that the antenna can achieve good forward radiation. There are two coupling paths between the closely placed antennas: the coupling between the adjacent antenna arms and the coupling with the reflector. By adjusting the phase constants of the two coupling paths, good isolation is achieved in the operating frequency band without any additional de‐coupling structures. A sample of a two‐element MIMO antenna is fabricated at the centre frequency of 5.1 GHz with a bandwidth of 330 MHz. Measured results show good performance to support the design method. As each arm is about 1/8λ0 (λ0 is wavelength in free space), the edge‐to‐edge distance is 0.04λ0, and the isolation in the operating frequency is 15 dB.

“…With the advantage of controllable dispersion properties, the corrugated SWTLs can achieve a specific phase delay without changing the longitudinal length, which brings much convenience to the circuit design. In recent years, corrugated SWTLs are popular candidates in the design of microwave circuits, such as miniaturized antennas [1][2][3], miniaturized power dividers [4], antenna feeding networks [5], and broadband baluns [6].…”

In this article, the average power handling capability (APHC) of corrugated slow-wave transmission lines (SWTLs) is investigated. Firstly, the attenuation constants of conductor and dielectric are extracted by the multiline method. Secondly, the thermal resistance of corrugated SWTLs is analyzed based on the constant-angle model. To deal with the non-uniform corrugated structure of SWTLs, the concept of average heat-spreading width (AHSW) is introduced. Finally, the APHC of the corrugated SWTL is calculated using the attenuation constant and the thermal resistance. In addition, the APHC considering the temperature-dependent resistivity of metal conductor is also presented. For validation, the APHCs of SWTLs with different geometric parameters are evaluated. The results agree well with those obtained by the commercial software.

“…In the last decades, microstrip patch antennas (MPAs) have been extensively considered by engineering researchers due to their low profile, rugged, lightweight structure, simple fabrication, and their compatibility with microwave integrated circuits, and capability to be easily formed into arrays [1][2][3]. These advantages make the microstrip patch antennas suitable for handheld wireless communication systems, mobile equipment, radio frequency identification (RFID), and aircraft radomes, missiles, satellites and various radars [4][5][6]. Nevertheless, the conventional MPAs have the disadvantages of low gain, low profile radiation characteristics, and their narrow impedance bandwidth that is typically a few percent because they are highly resonant structures [2,7,8].…”

In this work, modal characteristics have been rigorously studied which germinate an improved, accurate, and efficient computer-aided design (CAD) formulation to estimate the resonant frequency of sectorial circular microstrip antennas printed on anisotropic suspended and composite substrates. The obtained results demonstrated that the resonant frequencies of the sectorial circular microstrip patch on suspended and composite substrates can be adjusted to obtain the maximum operating frequency of the antenna. The computed results show a fairly good agreement with measured results. Such theoretical validation and results may prove to be more useful for design engineers and further investigation.
