Circularly Polarized Antenna Array Fed by Air-Bridge Free CPW-Slotline Network

International Journal of Antennas and Propagation, 2017
A novel design of 1×2 and 2×2 circularly polarized (CP) microstrip patch antenna arrays is presented in this paper. The two CP antenna arrays are fed by sequentially rotated coplanar waveguide (CPW) to slotline networks and are processed on 1 mm thick ...

An efficient 1-D periodic boundary integral equation technique to analyze radiation onto straight and meandering microstrip lines [PDF]

, 2012
A modeling technique to analyze the radiation onto arbitrary 1-D periodic metallizations residing on a microstrip substrate is presented. In particular, straight and meandering lines are being studied. The method is based on a boundary integral equation,

Antenna-coupled TES bolometers used in BICEP2, Keck array, and SPIDER

, 2015
We have developed antenna-coupled transition-edge sensor (TES) bolometers for a wide range of cosmic microwave background (CMB) polarimetry experiments, including BICEP2, Keck Array, and the balloon borne SPIDER. These detectors have reached maturity and

Sequentially Rotated Array Microstrip Antenna [PDF]

The Journal of Korean Institute of Electromagnetic Engineering and Science, 2007
In this paper, The four types SRA(Sequential Rotated Array) antennas has been analyzed. Those are consisted of a 4-elements SRA, a 8-elements SRA, the planer array SRA and the triple (4+8+4)-elements SRA. These LHCP SRA antennas are used a probe feeding multi-layer truncated microstrip antenna whose center frequency is 11.85 CHz. The cooperated feeding
