Patent ID: 8457244

Claim:
An antenna and radio arrangement, comprising: at least a first antenna, having a first antenna port and a second antenna port; a second antenna, having a first antenna port and a second antenna port; at least a first transmitting means, a second transmitting means, a third transmitting means, and a fourth transmitting means, where the first antenna's first antenna port is connected to the first transmitting means, the first antenna's second antenna port is connected to the second transmitting means, the second antenna's first antenna port is connected to the third transmitting means, and the second antenna's second antenna port is connected to the fourth transmitting means; a number of receiving means, such that each group of one transmitting means and two receiving means forms one transceiver unit; wherein at least two transmitting means transmit signals to the corresponding antenna ports, said signals being modulated by the same stream of digital signals and having the same radio carrier frequency, thus accomplishing a spatial combining of the output signals; and wherein the four receiving means of two transceiver units are connected to the first antenna's first antenna port, the first antenna's second antenna port, the second antenna's first antenna port and the second antenna's second antenna port such that a 4-Way Receiver Diversity, 4WRD, receiver functionality is obtained.
