Radiation enhancement in PCB plane using novel multi-stub inverted F antenna
2016
In this paper, a novel printed circuit board (PCB) antenna referred to as Multi-Stub Inverted F Antenna is proposed. The proposed antenna has enhanced radiation in the plane of PCB, as compared to traditional Inverted F Antenna. The proposed Multi-Stub methodology is verified in simulation and measurement by designing antenna at 2.45 GHz, which is widely used in portable wireless consumer products. The antenna dimension is 25.3 mm × 16.0 mm with measured gain of 0.8 dBi. Gain variation of the proposed Multi-Stub antenna in the PCB plane is well within 2.8 dB, as compared to 9.2 dB variation in traditional inverted F antenna. The proposed Multi-Stub methodology can be adopted in existing PCB monopole antennas as well, to enhance their radiation, particularly in the PCB plane.
