In this paper, the research advances in silicon based millimeter wave and THz ICs in the State Key Laboratory of Millimeter Waves is reviewed, which consists of millimeter wave amplifiers, mixers, oscillators at Q, V and W and D band based on CMOS technology, and several research approaches of THz passive ICs including cavity and filter structures using SIW-like (Substrate Integrated Waveguide-...

In this paper, a slot antenna array based on half-mode substrate integrated waveguide (HMSIW) is presented, integrating series of linearly tapered slots for wireless broadband applications in millimeter-wave frequencies. The are etched the upper layer HMSIW, which radiates energy from open side exhibiting near broadside radiation pattern. Two identical sets back-to-back printed arrays cross-lap...

In this paper, a cruciform coupler with half mode substrate integrated waveguide structure is presented. The prototype coupler consists of four half mode SIW structures crossing each other in right angle and two metallic posts are inserted in free section of junction in order to reach the coupling properties. Compact size and broadband operation are the features of this coupler. The size of cou...

Log-periodic array antennas have been investigated over a long period of time, the reason for the same being its provision of a constant radiation performance and good reflection coefficient performance over a wide frequency band, which can be considered as an important characteristic of this type of antennas. It created a high impact on development of new generation antennas with advanced feat...

In this paper, we propose a novel Half Mode Substrate Integrated Coaxial Line (HMSICL) cavity fed monopole antenna at 28 GHz. A SICL is bisected along its symmetric magnetic wall (PMC) to create an open-ended cavity. The proposed HMSICL used excite tapered radiate in endfire direction with gain of 6.4 dBi For dual beam application, it integrated unidirectional broadside Waveguide (HMSIW) exhibi...

A substrate-integrated waveguide (SIW) antenna is an implementation of a in microstrip antenna. The antenna, as low-profile suffers from narrow impedance bandwidth. This paper proposes novel bandwidth enhancement method for solving Bandwidth was achieved by using quad-resonant frequencies. frequencies are resulted the hybrid half-mode (HMSIW) cavities between inner and outer cavities. HMSIW cav...

Beamwidth-reconfigurable antennas are useful for the intersatellite link of low earth orbit formation flying and constellation, as they prevent unauthorized satellites from eavesdropping. In this article, a circularly polarized slot array antenna based on half-mode substrate-integrated waveguide (HMSIW) K-band beamwidth reconfiguration is proposed using new radio frequency (RF) switch structure...
