An antenna disposed on a substrate includes a radiating portion, a first coupling and feeding portion, and a second coupling and feeding portion. A length of the radiating portion is substantially equal to a half wavelength of electromagnetic signals radiated by the radiating portion. Each coupling and feeding portion includes a feeding part and a coupling part. The feeding part feeds the electromagnetic signals to the radiating portion via the coupling part so as to achieve effects of a multiple-input multiple-output (MIMO) antenna.

Antenna for achieving effects of MIMO antenna

An antenna disposed on a substrate includes a radiating portion, a first coupling and feeding portion, and a second coupling and feeding portion. A length of the radiating portion is substantially equal to a half wavelength of electromagnetic signals radiated by the radiating portion. Each coupling and feeding portion includes a feeding part and a coupling part. The feeding part feeds the electromagnetic signals to the radiating portion via the coupling part so as to achieve effects of a multiple-input multiple-output (MIMO) antenna. A gap is defined between the coupling part and the radiating portion to improve an isolation of the MIMO antenna.

A compact automatic gain control module for an RF amplifier includes a microchip Tuner for detection of pilot signals in an incoming RF signal. By selectively tuning into pilot signals in response to command from an on-board microprocessor, the module is frequency agile in the selection of pilot signals, selecting specifically advantageous signals for use as a pilot. Use of a microprocessor also enables specific advantages in receiving firmware upgrades to incorporate algorithms for operation parameter monitoring and adjustment of response in accord with monitored parameters. Such monitoring also enables the recording of on-module events that enable storage of a log to enable maintenance and performance enhancement within the module.
