In this paper, a broadband microstrip array antenna with rectangular waveguide mode transition operating at lower E-band is proposed. The microstrip array antenna is corporate-feed structure configured by microstrip line with a mode transition from rectangular waveguide. Broadband operation can be achieved by using a slit in the transition and employing a set of feed point in the center of microstrip-line...
In this paper, a bandpass filter (BPF) at 60 GHz band based on new design procedure is presented. The BPF is constructed by quartz-based post-wall waveguide (PWW) due to its lower dielectric loss. Filter design is achieved by optimization theory and burden for design is reduced by modeling filter as two dimensional structure. The 2D model is analyzed by using the method of moment (MoM) with global...
This work demonstrates a millimeter-wave photonic phased array where the input millimeter-wave is generated by a frequency quadrupling technique. The array consists of an external dual-parallel Mach-Zehnder modulator (DPMZM), an optical amplifier and a wavelength-division-multiplex (WDM) coupler. A wavelength-division-multiplexed optical signal from multiple lasers is inputted into the DPMZM and modulated...
In this paper, a corporate-feed array antenna with multi-layered glass substrate operating at 70-GHz band is proposed. The array antenna has slot and microstrip radiation elements with post-wall waveguide corporate-feeding circuit. The feeding circuit and radiation elements are fabricated on separated glass substrates which are connected by diffusion bonding for Cu. Reasonable agreement in both reflection...
A millimeter-wave antenna directly fed by waveguide is proposed. The antenna has a simple dipole element fed by a microstrip-line (MSL) which is connected to a WR-15 waveguide via a wideband mode-transition. The antenna element and the feeding MSL are structured on a low-loss single-layered liquid crystal polymer (LCP) substrate. In order to connect the MSL to the WR-15 waveguide with a wideband operation,...
In this paper, a broadband waveguide WR-15 to microstrip-line (MSL) transition is proposed. The transition is structured on a multi-layered liquid crystal polymer (LCP) substrate. The substrate has two LCP layers and a metal back-short block is mounted on the substrate and is connected to ground plane. The WR-15 waveguide is directly connected to the substrate and is coupled with the MSL via rectangular...
In this paper, a broadband mode-transition between grounded coplanar waveguide (GCPW) and post-wall waveguide (PWW) is proposed. The transition is composed of GCPW, microstrip line (MSL) and PWW. The transition is fabricated on liquid crystal polymer (LCP) substrate due to its low dielectricity and availability of roll-to-roll process for fabrication of devices with cost reduction. The GCPW GSG pad...
In this paper, a microstrip comb-line array antenna with parasitic elements for bandwidth enhancement at 60 GHz band is proposed. The antenna is fabricated on liquid crystal polymer (LCP) substrate due to its low dielectric loss. The antenna consists of a waveguide-to-microstrip mode transition, 16 radiation elements which construct an one-dimensional array and a terminated element. Two side-coupled...
In recent years, millimeter-wave technology has attracted much attention in high-speed wireless communications, imaging and radar applications. Low-cost devices are very important for prevalence of the technology in consumer applications. Antennas for such applications are required to have high gain and low loss due to the high absorption in air-propagation and the high operation frequency. In this...
