Abstract

A radio frequency (RF) module for use in a communication device of a communication system includes integrated RF circuitry comprising at least one of a transmitter and a receiver, and an antenna element having at least one portion thereof arranged substantially adjacent to and operatively coupled to the integrated RF circuitry. For example, the antenna element may include at least first and second portions having opposing edges arranged immediately adjacent respective first and second sides of the integrated RF circuitry. A plurality of the modules can be used to implement a transceiver in a communication system base station or other communication device.
