摘要
Antenna systems have an RF connector, a PCB dipole antenna, and a radome. The RF connector provides a direct connection to the PCB and limits PIM. An omni-directional WiFi antenna has a pair of horizontal dipole antennas on a PCB having different wavelengths and same frequency. An omni-directional UMTS dual antenna has a vertical arrangement of two independent antennas on a PCB and has a jumper printed circuit board connecting the RF connector to the upper antenna. Corresponding connectors, radomes, and ways of combining antenna elements on a single PCB are also disclosed. A single frequency omnidirectional antenna includes both half and full wavelength dipole elements. A plus-shaped radome enhances the omnidirectional radiation pattern of the enclosed antenna. A jumper printed circuit board allows independent antennas on a single circuit board without the degradation of internal coaxial connections. The connector provides a direct interface with a circuit board to reduce the number of parts and also reduce passive intermodulation.
