An electronic device includes a casing, a first antenna assembly, a second antenna assembly and a third antenna assembly. At least one of the first antenna assembly, the second antenna assembly and the third antenna assembly is rotatably disposed on the casing, and the rest are fixed on the casing.

A compact mobile high-frequency Antenna that quickly and quietly self-adjusts to minimize Voltage Standing Wave Ratio (VSWR). Includes a compact tuning coil and a rolling contact. A Reentrant cap serves as a capacitive top hat. A spiral cut enhances the efficiency is this very short antenna. A tough insulating tube covers the antenna to serve as a radome protect the user from RF burns. The use of rolling contacts on a smooth inside diameter of the tuning coil greatly reduces the force to move the contactor as well as the acoustical noise generated when tuning. A controller drives a servo motor to position the contactor to the optimal position within the tuning coil and selects the impedance to connect between the unused end of the tuning coil and the feed point of the antenna to optimize VSWR.

An array antenna includes a flexible substrate formed by stacked liquid crystal polymer (LCP) layers and has at least one feed point. At least one serial antenna is arranged on the flexible substrate, and a microstrip is extended from the feed point to connect a plurality of radiating elements in series to form the serial antenna. The tail end one of the radiating elements of the serial antenna is connected to one end of a ground microstrip, and another end of the ground microstrip is short-circuited to the ground. The length of the ground microstrip is approximately one fourth of the wavelength of the center frequency of the array antenna. Feeding sections where microstrips feeding to the radiating elements are in a horn and/or groove shape. Desired frequency and bandwidth may be obtained by adjusting lengths and widths of feeding sections respectively.

In some embodiments, a radio frequency identification (RFID) tag system includes a first strap mounting pad of an RFID antenna component, and a second strap mounting pad of the RFID antenna component, the second strap mounting pad being electrically coupled to the first RFID strap mounting pad. At least one of the first strap mounting pad and the second strap mounting pad may extend diagonally with respect to a wide edge direction of the antenna component, thus making the RFID antenna component configured to receive both a strap that is parallel to a wide edge direction of the antenna component and a strap that is perpendicular to a wide edge direction of the antenna component.
