Enrichment of Package Antenna Approach With Dual Feeds, Guard Ring, and Fences of Vias
IEEE Transactions on Advanced Packaging, 2009 This paper enriches the package antenna approach to wireless modules by introducing the dual feeds, the guard ring, and fences of vias. The dual feeds enable the antenna for not only single-ended but also differential signal operations. The

IEEE Transactions on Antennas and Propagation, 2017 A reflectarray antenna capable of operating independently in the transmit frequencies (from a satellite) in Ku-band (11–13 GHz) and Ka-band (19–20 GHz) has been proposed and demonstrated. To prove that independent beams can be optimized in each frequency

Improvement of a Circular Microstrip Antenna Excited by Four Feeds and Suspended with Artificial Magnetic Conductors [PDF]
International Journal of Antennas and Propagation, 2013 The proposed antenna is a circular microstrip structure excited by four feeds and suspended with artificial magnetic conductors (AMCs). The multifeed circular microstrip antennas can generate a high circularly polarized performance by using a different ...
