A passive multi-beam antenna systems with beamforming technology that can be used to increase quality of service, network capacity, and spectrum to meet the current and future demand of data usage and network capacity is presented. The system presented can produce as many as 32 narrow high-gain beams in a 120° sector with beam crossing set to be between 3 to 10 dB. Each beam provides a capacity and throughput multiplication over a traditional cell site. Frequencies can be reused in a sector resulting in a spectrum multiplication of as many as 32 times. With the use of multiplexers several channels can be combined and transmitted in each beam providing multiband/ multichannel transmission with a single antenna system to further increase user capacity and throughput.
Microstrip antennas are widely used in the wireless industry due to their high gain and low profile. Dual polarized antennas can obtain higher data rates, and a more stable link between customer and provider in telecommunications. Conventional dual polarized antennas consist of two independent elements positioned orthogonal to one another, increasing cost, size, and weight. In this paper, we will discuss the design of a dual polarized antenna array which uses dual polarized single element radiators on a very thick substrate material of various εr using probe feeding technique. An ETI patent pending feed line design is introduced to increase cross polarization rejection while scanning, further increasing the reliability of wireless communication.
