PIFA ANTENNA WITH HIGP STRUCTURE |
摘要 |
An antenna device for a small communication module providing increased bandwidth as well as a method for obtaining such an arrangement are disclosed. The invention combines characteristics of Planar Inverted F Antennas (PIFA) and High Impedance Ground-Plane (HIGP) structures to increase the bandwidth of the PIFA by utilizing a Photon Band Gap (PGB) structure and additionally using an optimized counterpoise size. By inserting a high impedance ground-plane inside a Planar Inverted F Antenna (1) it is possible to increase the bandwidth of the antenna without increasing its height. By additionally optimizing the size of a present counterpoise (10) cooperating with the antenna device, a best possible bandwidth of the device is obtained. By the use of a PBG structure for the embedded high impedance ground-plane in combination with the matched counterpoise it is then possible to obtain a further increased bandwidth. |
