Dual-Band Dual-Polarized Scalable Antenna Subarray for Compact Millimeter-Wave 5G Base Stations
IEEE Access, 2020 A dual linearly-polarized antenna subarray that operates at 28 GHz and 38 GHz is proposed for fifth generation (5G) base stations. In contrast to earlier millimeter-wave base-station antennas that implement individual single-band antennas, simultaneous ...

Simulation Design of Reconfigurable Multifrequency Yagi Antenna
IOP Conference Series: Earth and Environmental Science, 2020 Abstract In order to reduce the operating cost and improve the benefits of communication system, it is a feasible scheme to reduce the number of antennas used while ensuring the communication quality. Because reconfigurable antenna has the characteristic of automatically changing a certain electrical characteristic parameter, it has ...

Multifrequency radio observations of SNR J0536-6735 (N 59B) with associated pulsar [PDF]
, 2012 We present a study of new Australian Telescope Compact Array (ATCA) observations of supernova remnant, SNR J0536-6735. This remnant appears to follow a shell morphology with a diameter of D=36x29 pc (with 1 pc uncertainty in each direction).

Compact loaded PIFA for multifrequency applications [PDF]
, 2010 A new multifrequency microstrip patch antenna is presented. The antenna can be considered a PIFA since it has a metallic wall on one of its sides. The different bands of operation are independent of each other, and different radiation patterns for each ...
