An aperiodic substrate integrated waveguide (SIW) wide‐angle scanning phased array with low side‐lobe levels (SLLs) is presented. The proposed C‐band array has 16 SIW‐slot elements with aperiodic distribution. The TE10 mode of each element is excited to obtain a wide beamwidth for wide‐angle scanning potential. In addition, a genetic algorithm is used to optimize the placement of the elements to reduce the scanning SLLs of the phased array, especially in wide‐angle scanning areas. The proposed approach provides superior performance of SLLs < −11.5 dB, particularly small gain fluctuation (±1.5 dB) when scanning form −68° to +68°. Compared with the same aperture uniform array, the scanning angle and the SLLs of the proposed array have been significantly improved.

“…A substrate integrated waveguide (SIW) cavity-back slot is an excellent form that can replace the aperture coupling method while also ensuring a seamless characteristic for the MPA ground plane [14]. Since the advent of SIW technology [15], there has been sufficient development of components operating in the microwave and millimetre-wave region [16].…”

A Wideband Circularly Polarized Microstrip Patch Antenna With Embedded Shielding Package Based on Quarter-Mode Substrate Integrated Waveguide Feed

In this paper, the feasibility of using the half-mode/quarter-mode of a substrate integrated waveguide (HMSIW/QMSIW) cavity to feed microstrip patch antennas (MPAs) is explored; based on this, a circularly polarized (CP) MPA fed by the sequential rotation QMSIW cavities is proposed. For more compact and higher integration, the active circuits are packaged inside the microstrip patch antenna. Correspondingly, the QMSIW cavities have also been chamfered, and slots are designed on the upper surface to reduce the influence of the chamfer operation. The SIW cavities introduced an additional resonant mode, which can essentially enhance the bandwidth of the MPAs. The fabricated prototype shows a bandwidth of about 9% (1.42GHz-1.55GHz) with an average CP gain of 7 dBic. In addition, the adoption of HMSIW/QMSIW cavity excitation allows the microstrip patch antenna to retain a seamless ground plane as well, which facilitates further integration with other components of the communication system by printed circuit board lamination technology.

A novel differential filtering patch antenna with high selectivity

A novel differential filtering antenna with high selectivity is proposed. The antenna is mainly composed of three different‐size patches, a slot, a pair of differential feeding lines, and a line resonator. An air gap is adopted to improve the impedance bandwidth and the filtering performance. The line resonator helps to generate high common‐mode (CM) rejection. Owing to the parasitic concave and convex patches, the filtering performance and the bandwidth of the antenna are enhanced. The parasitic concave patch affects the lower band‐edge selectivity while the parasitic convex patch influences the upper band‐edge selectivity. In addition, the frequencies of two radiation nulls can be controlled independently to achieve two high sharp roll‐off rates by adjusting the lengths of the parasitic patches. Considerable impedance matching bandwidth is achieved through an aperture coupling. Finally, a prototype of the differential filtering antenna is fabricated and tested. The measured results are in good agreement with the simulated results, showing an impedance bandwidth of 9.9% and an average realized gain of 7.5 dBi. Besides, two filter zero transmissions located at 3.40 and 3.84 GHz produced two radiation nulls.
