A plurality of first metal sheets parallel to each other are arranged at intervals on a front surface of the substrate, a plurality of second metal sheets parallel to each other are arranged at intervals on a back surface of the substrate, and the first and second metal sheets are correspondingly staggered and coupled by a coupling part running through the substrate. The microstrip line filtering radiation oscillator has functions of signal radiation and interference suppression. The filtering radiation unit includes at least one oscillator and can be used in conjunction with a high-frequency radiation unit, to radiate high-frequency and low-frequency signals simultaneously. The antenna includes at least one filtering radiation unit, and can transmit low-frequency and high-frequency signals simultaneously, thereby effectively improving the integration and reducing the volume of the antenna.

Abstract: An antenna element transfers a radiofrequency signal and dissipates heat. The antenna element includes a periphery and first and second pairs of fins. The periphery has a length and a width with the length approximately equaling the width. The first and second pairs of fins extend in height from inside the periphery. The first pair of fins are separated by a shared gap for transferring a first polarization of the radiofrequency signal, and the second pair of fins are separated by the shared gap for transferring a second polarization of the radiofrequency signal that is orthogonal to the first polarization. An antenna array includes multiple instances of the antenna element for transferring the radiofrequency signal and for dissipating the heat.

Abstract: Antenna waveguide transitions for solid state power amplifiers (SSPAs) are disclosed. An SSPA includes a waveguide channel that is configured to propagate an input signal, such as an electromagnetic signal, from an input port to a solid state amplifier for amplification. The waveguide channel is further configured to propagate an amplified signal from the solid state amplifier to an output port. Waveguide transitions to and from the solid state amplifier are bandwidth matched to the waveguide channel. Additionally, the waveguide transitions may be thermally coupled to the waveguide channel. The waveguide transitions may include antenna structures that have a signal conductor and a ground conductor. In this manner, the SSPA may have improved broadband coupling as well as improved thermal dissipation for heat generated by the solid state amplifier.
