In the realm of modern telecommunication and radar systems, the evolution of waveguide technology has been pivotal in facilitating the transmission of electromagnetic waves with enhanced efficiency and reliability. Among various waveguide designs, the double ridge waveguide stands out as a significant innovation, offering unique characteristics that cater to specific industry needs. Understanding its structure, […]

To achieve complete coverage with a minimum s-band antenna gain of -7 dBi, a straightforward configuration utilizing dual circularly polarized microstrip patch antennas was employed. The configuration involved the implementation of a wide bandwidth, dual circularly polarized truncated corner microstrip antenna, which was complemented by two parasitic patches. To enhance the cross polarization bandwidth, diagonally embedded holes

Dolph Microwave finished production 4.5 Meter Turning Head Antenna and test of Ext. Ka-band Tx27.5 to 31.0 GHz, Rx17.7-21.2GHz satcom antenna with 4 port Circular Pol. Axis Ratio 0.6dB. Product & Pedestal Features:  Wide variety of feed options designed to meet the latest international standards. S, C, X, Ku, DBS and Ka Band, Tx/Rx, 2Tx/2Rx, TT&C,

There are two types of curved waveguides: E-surface curved and H-surface curved. The curved waveguides include arc-shaped curved waveguides and cut-angle curved waveguides. Cut-angle curved waveguides can be used in situations where the arm length is short, the waveguide is large, the bandwidth is narrow, and the power is low. The standard bending angle is 90°,

Antenna feeds and RF networks as the heart of antenna system from Dolph Microwave is R&D by experienced our engineers who engaged into satcom and RF field for years. The components can be offered including OMT, duplixer, filter, phase shifter and feedhorn etc. covering different bands like C-band, Ku-band, Ka-band, S-band. X-band and required dual band etc. Our
