“…A compact microstrip Yagi antenna based on HMSIW was proposed in [4], achieving a relative bandwidth of 10.8% while achieving miniaturization. Introducing slits on a QMSIW structure can achieve the purpose of multifrequency [5,6] and increase the bandwidth [7]. A bandwidth of 414 MHz was measured in [8] using two eight-mode resonators coupled to each other and exhibiting elliptical polarization.…”

In this paper, a low-profile dual circularly polarized (CP) antenna for Ku band satellite communication is proposed. A quarter-mode SIW (QMSIW) is designed as a circular polarization unit, which realizes circular polarization by using high-order mode TE 130 , and a pair of units are combined to form the antenna proposed in this paper. Feeding different units can realize left-handed circular polarization and right-handed circular polarization, respectively. The antenna impedance bandwidth is 5.66 ; the circular polarization bandwidth (CPBW) is 540 MHz (15.64 GHz-16.18 GHz); and the gain in the passband is 5.1 dBi, with a minimum axial ratio (AR) of 1 dB. The thickness of the antenna is only 1.5 mm, which has obvious low-profile characteristics.

“…Various techniques have been used to reduce the size of SIW based antennas, filters, power dividers, etc. [7][8][9][10][11]. A half-mode SIW (HMSIW), which occupies half the area of its full mode counterpart, is first introduced in [7] and later used in [8] to design compact SIW power divider.…”

“…A half-mode SIW (HMSIW), which occupies half the area of its full mode counterpart, is first introduced in [7] and later used in [8] to design compact SIW power divider. Similarly, quarter-mode SIW (QMSIW) is used to miniaturize the antenna [9]. Also, QMSIW and 1/8th mode SIW (EMSIW) are used in [10,11] for miniaturization of SIW based devices without affecting the performance.…”

A novel compact 4-way power divider is presented here, which consists of 1/64 th mode elliptically curved substrate integrated waveguide (SIW) resonators and radial transmission lines. A direct coaxial fed circular patch acting as a radial transmission line is connected with four elliptically curved 1/64 th mode SIW resonators, and these resonators are then connected to output terminals. An equivalent circuit model is developed to understand its behavior. It is designed to operate at 3.6 GHz covering the frequencies assigned for 5G in sub-6 GHz band. Conventional PCB techniques are used to fabricate the prototype. The measured bandwidth is 2.2 GHz, ranging from 2.5 GHz to 4.7 GHz, for which the return loss is less than −10 dB. Also, the transmission coefficient between input and each output for the above-mentioned frequency band is −6.4 ± 0.5 dB. It has a very compact footprint of 0.32λ 2 g , which is at least 40% smaller than various SIW based state of the art power dividers.
