Antenna-in-Package(AiP) technology has an advantage that a system can maintain antenna performance while being small in size and highly integrated. In this paper, based on LTCC technology, a rectangular corner cut microstrip antenna for 5G communication band is designed, and then integrated into a package of the chip with AiP technology. The simulation results of HFSS software show that after miniaturized and highly integrated, the AiP system achieves the goal with operation frequency of 4.8 ~ 4.9GHz, bandwidth of 100MHz and the peak gain of 6.52dB.

In this paper, neural network modeling techniques are used to model and solve the inverse problem of the Near-Field Power Pattern Control. The near-field intensities as the input to the inverse model, whereas the source phases are the output. The effect of the size of the training data set on the accuracy of the results is investigated. Extensive numerical tests indicate that the results predicted by the proposed models are in excellent agreement with the theoretical data obtained from the existing analytical solutions of the forward problem.

Substrate integrated waveguide slot antenna arrays are designed and employed for monopulse radar applications at microwave and millimetre-wave frequencies. This research shows the advantages of using 2x2 MIMO-monopulse radar processing opposed to a more conventional 2x2 MIMO radar. The developed technique, MIMO-monopulse is especially useful when resolving two targets positioned closely together as demonstrated in this research. Results show proof-of-concept for the developed radar system architecture, which operates at 24 GHz, but can easily be scaled to 77 GHz. Classical monopulse radar is commonly used for adaptive cruise control as it allows for a high angular resolution at long distances. Combining MIMO with monopulse can foster the many benefits of MIMO radar with the high angular resolution possibilities of monopulse processing.

In this paper, a novel compact leaky-wave antenna (LWA) with high gain, broadband and wide scanning range is proposed. This design is mainly based on traditional spoof surface plasmon polaritons (SPPs) slow-wave transmission line (TL). By modulating the spoof SPP slow-wave TL with sinusoidal periodic contour, one planar frequency beam scanning antenna (FBSA) is realized with "-1"-order harmonic mode and beam steering property, from backward direction through broadside to forward direction. Experimentally results exhibit that it owns a bandwidth from 10 to 16 GHz (46.2%) with beam scanning range from -36° to 65°. The maximum gain of the prototype is 16 dBi within the whole operating band.

In this paper, an electrically small magneto-electric dipole for ultrahigh frequency radio frequency identification tags is proposed. The proposed antenna is composed of a split ring resonator and a meandering-arm dipole, which are printed on the top and bottom of the printed circuit board, respectively. The excitation port is placed across a cut opened in the external ring of the split ring resonator, and the dipole is fed by proximity coupling. The simulation results show that a heart-shaped radiation pattern with 4.43dB gain is obtained.

A wideband differential-fed patch antenna with high isolation and high selectivity is presented. The differential-fed method is used to provide the antenna with high polarization isolation characteristic. A parasitic patch is adopted in the design not only to improve the impedance bandwidth, but also to generate a radiation null at the upper band-edge. Filtering response is improved by etching slots and loading resonant stubs on the feeding lines. Simulated results show that the proposed DFDP filtering antenna has an operation band of 34.16% (from 3.86 to 5.45 GHz) for |Sdd11| < -10 dB and a maximum gain of 9.64 dBi, and the cross-polarizaiton level is below -27 dB. Moreover, a high out-of-band gain-suppression level which reaches 21.9 dB is also obtained.

A compact dual-band textile antenna operating in the 3.5-GHz WiMAX band and the 5.8-GHz industrial, scientific, and medical band, is proposed for wearable devices. The dual-band operation is activated by using different modes. The antenna has the advantages of good human shielding function and achieves a rather small dimension of 43.8 mm × 43.8 mm × 2 mm (0.51 λ0 × 0.51 λ0 × 0.02 λ0) by adopting a quarter-mode substrate integrated waveguide structure. Due to the fact that the proposed antenna is made of the flexible textile material, it can be conformal to the human body. Detailed analysis and simulation results show that the antenna has stable performance under bending and in proximity of human phantom.

This paper presents a rectangular reconfigurable waveguide filter to switch between stop-band and pass-band state according to demand. Irises and stubs are used to construct and modify the waveguide’s inner cavity structure, so as to formulate different filtering patterns. To verify the concept, we simulate a bandstop filter and a bandpass filter respectively. In such a design, state switching can be realized with great convenience and reliability through filter attitude adjustment. Furthermore, multifrequency switch can be implemented by cascading several filters of different working frequencies. This device can be used in antenna system for interference resisting or channel selecting.
