A set of hybrid microstrip patch and semi-circular cavity antennas is introduced. The semi-circular cavity is implemented using Half-mode Substrate Integrated Waveguide (HMSIW) technique. Different shapes of patch include rectangular, semi-circular and equilateral triangular are excited using proximity effect by the circular SIW cavity at its TM010 mode of operation. The whole structures have b...

An approach for improving the gain of leaky-wave antenna (LWA) is presented in this paper. Embedding cavities structure leads to improvement. To validate proposed method, it was implemented on a half-mode substrate integrated waveguide (HMSIW) LWA. The HMSIW LWA realized low temperature co-fired ceramic (LTCC) achieve compact structure. key novelty improvement by using embedded without increasi...

This letter proposes a multi-passband half-mode substrate integrated waveguide (HMSIW) filter based on the theory of odd and even mode analysis. The adopts triangular HMSIW cavity cut along diagonal rectangle. By etching two dual-mode resonators, resonant resonator is coupled with odd-even to achieve multiple passbands. defected ground structure (DGS) can reduce resonance frequency without incr...

A novel filtering magic-T (FMT) with a compact size, broad bandwidth, and wide stopband rejection based on the dielectric-covered L-shaped groove (DCLSG) half-mode substrate integrated waveguide spoof surface plasmon polariton (HMSIW-SSPP) structure is proposed for first time. HMSIW (HMT) dual-layer substrates designed. Then, we construct FMT by periodically etching subwavelength DCLSG SSPP int...

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...

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 two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated. These are simply implemented using low cost single layer printed circuit board (PCB) process. The array element consists of a rectangular microstrip patch with appropriate dimensions in the vicinity ...
