The present invention provides a surge protection module which comprises a carrier board and a probe set. The carrier board is used to carry an electronic component. The probe set is disposed on the carrier board and has a plurality of probes and a short-circuit unit. Each probe is used for contacting the electronic component, and the short-circuit unit is selectively moved to a first position or a second position. When the short-circuit unit is moved to the first position, the short-circuit unit simultaneously contacts and shorts the plurality of probes. When the short-circuit unit is moved to the second position, the short-circuit unit is away from at least one of the plurality of probes.

The present invention provides a probe apparatus, which comprises a signal transmission device, a probe, and a bottom fixing device. The signal transmission device includes a first transmission part and a second transmission part. An end of the probe is connected electrically below the second transmission part. The bottom fixing device is disposed below the signal transmission device. An end of the bottom fixing device includes a first penetrating hole and a first recess is disposed below the end. The probe passes through the first penetrating hole of the bottom fixing device. The probe is located in the first recess. The bottom fixing device reinforces the mechanical strength of the signal transmission device so that the width of the signal transmission device can be reduced. Thereby, the benefit of high-density arrangement of the probe apparatus can be achieved.

A two-dimensional antenna array has n rows of 1&#xd7;m one-dimensional array and each one-dimensional array is composed of multiple single differential feeding antennas. Each single differential feeding antenna has a differential feeding structure and a microstrip antenna stripe. A longitudinal length of the microstrip antenna stripe is no longer than one wavelength in a dielectric medium, so the microstrip antenna stripe is not excited to a high-order mode. An angle of inclination of a main beam aligns with the broadside and a width of the main beam is further concentrated at elevation direction. The differential feeding structure can reduce an even mode to enhance an isolation. The one and two-dimensional antenna array is miniature by using the small single differential feeding antennas. Isolation and gain of a dual-antenna system using the two-dimensional or one-dimensional antenna arrays are further enhanced and increased if more feeding antenna arrays are used.
