TL;DR: In this article, a balanced band-notched ultra wideband (UWB) filtering circular patch antenna fed by a microstrip line is presented, which is composed of a λ/4 slotline-resonator-based balanced bandpass filter and a stub-loaded circular radiating patch.

TL;DR: In this paper, a balanced wideband (WB) planar inverted-F antenna (PIFA) integrated with a balanced WB bandpass filter (BPF) is presented in order to improve the differential mode (DM) passband selectivity and upper stopband rejection and meanwhile to increase the common mode (CM) rejection.

TL;DR: In this paper, a balanced diplexer and a balun Diplexers with high common-mode suppression and differential-mode isolation were proposed for the two channels of 2.45 GHz WLAN and 3.55 GHz WiMAX.

TL;DR: In this article, a differentially fed wideband circularly polarized (CP) slot antenna with two opposite-fed C-shaped radiating patches and a stub-loaded corner-truncated rectangular slot was proposed.

TL;DR: In this paper, a balanced single and dual-band bandpass fllters (BPFs) are constructed using two ring resonators, where open-circuited stubs are added to one of the two resonators so that the transmitted commonmode (CM) signals can be attenuated, and source-load coupling is established so that two transmission zeros are generated near the edges of each desired difierential-mode (DM) passband to sharpen the passband selectivity.
