A method for upgrading a dual-band antenna assembly to a tri-band antenna assembly is provided. The dual-band antenna assembly includes a main reflector, and first and second antenna feeds arranged in a coaxial relationship and directed toward the main reflector. The first and second antenna feeds are for first and second frequency bands, respectively. The method includes positioning a third antenna feed through a medial opening in a center of the main reflector, with the third antenna feed directed towards the first and second antenna feeds. The third antenna feed is for a third frequency band. A subreflector is positioned between the main reflector and the first and second antenna feeds. The subreflector includes a frequency selective surface (FSS) material that is reflective for the third frequency band and transmissive for both the first and second frequency bands.

A system is described for distributing over the air (OTA) channels within buildings and homes. The system can implement one or more active multi-mode antennas for improved performance and reliability. The system can be configured as a mesh network where multiple nodes are distributed to improve the probability of channel capture across the VHF and UHF frequencies used for over the air TV distribution. A node consists of a beam steering antenna that operates at the VHF and UHF frequencies for TV signal reception, a receiver and demodulation circuit, a transcoder to convert the received information for re-distribution, and a transceiver capable of operation at a secondary frequency band for use in re-distributing the information to communication devices in proximity of the node. The secondary frequency band can be the common WLAN (Wireless Local Area Network) system such as Wi-Fi, with the Wi-Fi transceiver also containing beam steering antennas for improved in-building propagation of the re-distributed information.

An antenna structure includes a first antenna, a second antenna, a third antenna, and a first grounding portion. The first antenna and the second antenna operate at a first frequency. The first antenna is disposed side by side with the second antenna, and the first antenna and the second antenna are orthogonally polarized. The third antenna operates at a second frequency, and the second frequency is lower than the first frequency. The first grounding portion includes a first side edge and a second side edge opposite to each other. The first antenna and the second antenna are connected to the first side edge and the third antenna is connected to the second side edge. An electronic device includes the said antenna structure.

A reconfigurable hybrid antenna arrangement is provided that includes an antenna housing, a passive multiband antenna positioned within a first section of the antenna housing, and a passive multiple-input multiple-output (MIMO) antenna that supports 5G wireless services that is removably positioned within a second section in the antenna housing. The second section is reconfigurable such that the passive MIMO antenna can be replaced with a second MIMO antenna to support enhanced 5G services, e.g., to upgrade 5G capabilities, and the replacement MIMO antenna utilizes existing space within the same antenna housing. In this manner, existing antenna structures that include a passive antenna array for supporting legacy wireless services can be reconfigured by adding another antenna to support network upgrades for new wireless services and doing so within the existing antenna structure to obviate any site-related issues, e.g., lack of available space and antenna size restrictions.
