Using injection matching theory as inspiration derived from radio frequency amplifier design, an electrically small antenna is produced. Previously, a one port injection matched antenna was produced and fabricated. In this paper it is demonstrated that by using the injection matching theory, simultaneous matching at both ports can also be achieved, which improves the overall efficiency of the two-port...
Two-port, electrically small, tunable antennas were recently realized based on injection matching theory, inspired by the Doherty radio frequency amplifier design technique. This paper proposes to use injection matching theory to achieve wide bandwidth operation for intrinsically narrowband antennas. The proposed technique is verified through simulation for a miniaturized, proximity-fed patch antenna...
Recently, a new approach, called injection matching theory (IMT), for realizing Electrically Small Antennas (ESA) was reported. This approach was validated by means of port matching improvement through the measurements in an earlier publication. This contribution considers the radiated power from an injection matched antenna. Measurements demonstrate that injection matching significantly improves...
In this paper a novel approach for making Electrically Small Antennas (ESA) is presented. For this purpose a two port configuration is used in which one port is exploited (the secondary port) in order to match the other port (the primary port) to the source. The simulated results shows that the proposed approach not only considerably improves the band width of operation, but also it allows frequency...
In this study, an approach for making electrically small antennas is proposed. In this technique, a two port configuration is utilised in which one port is exploited (the secondary port) in order to match the other port (the primary port) to the source. Based on the proposed approach a microstrip patch antenna is designed and fabricated. The simulated and measured results show that utilising the proposed...
