Summary: This study investigates a miniature frequency-tunable slot-loop antenna based on KNN material, which has competitive microwave properties and is suitable for frequency-agile antennas. By fabricating the antenna prototype on an MgO substrate and using laser microetching technique, successful tuning of the antenna center frequency is achieved. The KNN material demonstrates for the first time the potential for application in miniature tunable antennas.

Summary: The proposed single-layered slot antenna system operating at 5.8 GHz aims for in-band full duplex applications without the need for a coupler. High isolation is achieved by strong separation of even- and odd-mode feeds and the use of microstrip-coupled coplanar waveguides. The antenna system also boasts improved isolation with the inclusion of a lumped capacitor and has measured gains of 5.4 and 5.8 dBi at 5.8 GHz.

Summary: In this communication, a novel compact single whip wideband antenna with an improved omnidirectional wideband antenna is proposed. The single whip antenna shows a wide impedance matching performance in a frequency range from 194 to 2124 MHz, while an improved omnidirectional radiation pattern is achieved by co-designing three whipped antennas. The measured performance of the fabricated antenna agrees well with the simulation results.
