Cavity embedded GPS antenna in GSM wire‐patch radiating element

Abstract

operations. Reconfigurable antennas do not require stringent subsequent filtering stages and have demonstrated better S/N and antijamming features. Reconfigurable antennas can be geared toward either one service at a time to address switchable services or mixed services by using branched structures. In addition, relatively wide band filters can follow these reconfigurable antennas to eliminate any spurious higher order resonances and their associated added noise. Use of these filters would cause minimal insertion loss, and they have drastically reduced requirements compared with those of the RF front-end filters needed for multiband antennas. REFERENCES 1.
