dc.description.abstract© 2024 by the authors.Featured Application: This antenna can be used in the receiving front-end Digital TV indoor applications currently under test, where the transmission and reception benefits of MIMO operation are investigated. A broadband and compact planar UHF antenna is presented for use in MIMO Digital TV indoor applications. The choice of the element and its physical implementation is oriented towards a low-profile, low-cost, and single-layer deployment. Since it is intended to be used in a 2 × 1 MIMO array, two antennas were constructed and tested to minimize their coupling to provide larger MIMO gains. Regarding the excitation, two different structures were evaluated to observe their impact on the final impedance profile. The option of an infinite balun provided a 62% fractional bandwidth (394 MHz to 747 MHz), covering the desired band and with good isolation levels when analyzed in the array. Results regarding MIMO parameters are provided herein, such as Envelope Correlation Coefficient and Total Active Reflection Coefficient, proving the potential of the proposed antenna array to be used in MIMO Digital TV applications in covering the UHF band.
