“…One of possible solution to reduce or eliminate this problem is radiating the microwave in circular polarization (CP) [2]. In the dual feed design for square microstrip antenna, the CP radiation can be achieved by providing current with equal amplitude and mutual phase difference of 90 0 [3]. The antenna performance of this CP antenna, however, was not satisfactory in terms of both 3-dB axial ratio bandwidth and antenna gain.…”

A novel circularly polarized microstrip antenna using dual-feed orthogonal and with front-end parasitic method is proposed in this paper. In the feeding network, a two-way circular-sector power divider is adopted to distribute the current equally to each feed. A method of moments is employed for optimizing the design and achieving a good circular polarization at the center frequency of 2.37 GHz. The simulated values shows that 3-dB axial ratio bandwidth and maximum gain are about 51MHz and 6.39dBic. The narrow bandwidth and reasonable gain indicate that antenna is promising for Inter Satellite Link in S-Band.Index Terms -Circular polarization, dual-feed orthogonal, and front-end parasitic.

A design for Ka-band satellite communication antenna in earth station is introduced. This kind of antenna uses splash plate feed based on ring-focus antenna. The theory of the new splash plate feed design is presented and the relative equations are derived. The measured antenna parameters, VSWR, and patterns are highly consistent with the simulated results, which demonstrates the success of the design for such kind of antenna that can be effectively used in Ka-band applications.

This work presents a novel monolithic integration of a 30 GHz RF-MEMS Dicke switch network and a wideband LNA realised in a 0.25 μm SiGe BiCMOS process. The wideband LNA design has a measured gain of 10-19.9 dB at 2-33 GHz given a DC power consumption (PDC) of 35 mW and a measured noise figure of 5.4-6.3 dB at 14-26.5 GHz when PDC=7.5 mW (the LNA gain is then 10-14.2 dB at 4-26 GHz). The Dicke switch has 3 dB and 22 dB of losses and isolation at 25 GHz. The MEMS switched LNA gain was found to be 10-17 dB lower than anticipated due to some unintentionally missing metal via contacts between the Dicke switch and LNA ground planes. Despite this fact, the MEMS LNA resulted in a measured isolation of 9.0-13.5 dB at 24-31 GHz when the Dicke switch was switched ON and OFF which validates the switching function of the SiGe RF-MEMS wideband LNA design. Such reconfigurable low-power MEMS switched RFICs could be used in highly adaptive broadband receiver front-ends for wireless communication, sensor networks and imaging systems, for example.
