A Compact Diplexer for Circularly Polarized 20/30 GHz SIW-Antennas

, 2020
This contribution deals with a 20/30 GHz diplexer intended to feed substrate integrated waveguide (SIW) antennas. As these feature circular polarization, they have a square cross section which is implemented in a thick multilayer.

Single‐Layer, Dual‐Port, Dual‐Band, and Orthogonal‐Circularly Polarized Microstrip Antenna Array with Low Frequency Ratio

Wireless Communications and Mobile Computing, Volume 2018, Issue 1, 2018., 2018
A single‐layer, dual‐port, dual‐band, and dual circularly polarized (CP) microstrip array is designed for satellite communication in this paper. The operating frequencies are 8.2 and 8.6 GHz with a very low ratio of 1.05. First, a rectangular patch element is fed through microstrip lines at two orthogonal edges to excite two orthogonal dominant modes ...

Design and Analysis of Wideband Ladder‐Type Film Bulk Acoustic Wave Resonator Filters in Ku‐Band

Active and Passive Electronic Components, Volume 2013, Issue 1, 2013., 2013
This paper presents the design of ladder‐type filters based on film bulk acoustic wave resonator (FBAR) in Ku‐band. The proposed FBAR filter has an insertion loss of −3 dB, out‐of‐band rejection of −12 dB and 3 dB bandwidth of 1.0 GHz from 15 GHz to 16 GHz. Based on the characteristics of the FBAR filter, the expected characteristics of FBAR resonators

A Compact SIW K-/Ka-Band Diplexer with Integrated Reactive Power Divider

, 2021
A compact 20/30 GHz diplexer based on substrate integrated waveguide (SIW) cavities and grounded coplanar waveguide (GCPW) feed lines is proposed. It features additional in-phase reactive power splitting in both passbands by exploiting symmetries.

Wideband Millimeter‐Wave Balun‐Diplexer Based on a Novel Coupled Marchand Architecture for Compact Footprint and Phased‐Array Integration

Microwave and Optical Technology Letters, Volume 67, Issue 11, November 2025.
ABSTRACT This letter presents the first reported wideband balun‐diplexer for mm‐wave applications, designed for shared‐aperture full‐duplex array systems. By integrating balun and diplexer functionalities in a single component, we enable per‐element self‐interference suppression, while also facilitating the interface between the balanced feed of the ...

Three‐Way Equal Filtering Power Divider for Modern Communication Systems

Engineering Reports, Volume 7, Issue 1, January 2025.
A balanced three‐way filtering power divider that receives input power and delivers equal amount of output to its three output ports is developed and realized using microstrip technology. The design is well‐suited for modern communication systems due to its low insertion and return losses, sharp selectivity, and integrated filtering capability ...

Realization of a Wide Stopband Filter Using the Weakest Electric Field Method and Electromagnetic Hybrid Coupling Method

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2024, Issue 1, 2024.
To enhance filter performance in terms of stopband, we propose a wide‐stopband substrate‐integrated waveguide filter based on the rejection of higher‐order modes. The filter establishes the inner and outer coupling windows at the mode’s weakest electric field to achieve mode suppression.
