Guest Editorial Antenna-in-Package, Antenna-on-Chip, Antenna-IC Interface: Joint Design and Cointegration(IEEE Antennas and Wireless Propagation Letters, Institute of Electrical and Electronics Engineers (IEEE), 2019-11-05) [Article]The twenty peer-reviewed letters in this special section examine the design and cointegration of antenna-in-package (AiP), antenna-on-chip (AoC), and antenna ICs (AIC). The letters are categorized in the four distinctive categories: 1) Fabrication technologies (four); 2) Measurement strategies; 3) Applications; and 4) New design and integration strategies. Fruition of major thrusts such as 5G/6G, high-resolution radar and imaging, autonomous driving, and space technology are highly intertwined with the advance of applied electromagnetics. Miniaturization and seamless integration of microwave components and radio systems can enable superior performance, form factor, and cost efficiencies leading to enhanced proliferation of such applications. Historically, radio frequency front ends, antennas, and microwave components have separately evolved using distinct fabrication and measurement technologies.

Integrated reconfigurable multiple-input–multiple-output antenna system with an ultra-wideband sensing antenna for cognitive radio platforms(IET Microwaves, Antennas & Propagation, Institution of Engineering and Technology (IET), 2015-06-18) [Article]© The Institution of Engineering and Technology 2015. A compact, novel multi-mode, multi-band frequency reconfigurable multiple-input-multiple-output (MIMO) antenna system, integrated with ultra-wideband (UWB) sensing antenna, is presented. The developed model can be used as a complete antenna platform for cognitive radio applications. The antenna system is developed on a single substrate area of dimensions 65 × 120 mm$^{2}$. The proposed sensing antenna is used to cover a wide range of frequency bands from 710 to 3600 MHz. The frequency reconfigurable dual-element MIMO antenna is integrated with P-type, intrinsic, N-type (PIN) diodes for frequency agility. Different modes of selection are used for the MIMO antenna system reconfigurability to support different wireless system standards. The proposed MIMO antenna configuration is used to cover various frequency bands from 755 to 3450 MHz. The complete system comprising the multi-band reconfigurable MIMO antennas and UWB sensing antenna for cognitive radio applications is proposed with a compact form factor.

Miniaturized, low power, wireless transmitter and receiver with on-chip antenna, and wireless coupling of on-chip and off-chip antenna(2010-04-22) [Patent]A miniaturized, low power RF transmitter with a dual mode active on-chip antenna/inductor is disclosed in which antenna also serves as the oscillator inductor. Also disclosed is a miniaturized low power RF receiver with an on-chip antenna; and a RF transmitter system wherein an on-chip antenna is wirelessly coupled to an off chip patch antenna are disclosed. Advantageously, the TX chip is housed in a low loss, e.g. Low Temperature Co-fired Ceramic (LTCC) package with a patch antenna to provide a System-on-Package implementation comprising electromagnetic coupling between a RF TX chip comprising an integrated on-chip antenna and a package antenna. The on-chip antenna feeds the LTCC patch antenna through aperture coupling, thus negating the need for RF buffer amplifiers, matching elements, baluns, bond wires and package transmission lines, and significantly increases the gain and range of the module with respect to the on-chip antenna alone, without deterioration of the circuit performance and power consumption. Exemplary embodiments are disclosed which may be fabricated using standard CMOS technology, for operation in the 5 GHz U-NII band for applications such as miniaturized, low cost, low power wireless devices and sensor systems.
